Information on Acid Neutralizers for Home Well Water Treatment Systems

by

Gerry BulfinOn private water systems, one of the most common causes of corrosion is acidic water. Water that has a pH value of less than 7.0 is considered to be acidic. The ideal pH for most domestic supplies is between 7.0 and 8.0 on the pH scale.Signs of acid water are corrosion of fixtures, pinhole leaks in plumbing, and blue staining (from copper pipes) or rust staining (from iron pipes). Often these waters are great for drinking or household use, but are low in buffering calcium minerals, and contain dissolved carbon-dioxide gas, which can cause a low pH and acid condition. Without treatment, these waters can be contaminated with copper, lead and other metals from piping, fixtures and appliances, turning good water into contaminated drinking water.Treatment is accomplished by neutralizing the water with the use of an automatic neutralizer filter. These are water filter tanks filled with a media blend of calcium and magnesium carbonates made from naturally occurring minerals. This media, one brand of which is called Calcite, slowly dissolves into the water, raising the pH and making it less corrosive. More mineral can quickly and easily be added as needed to the filter tank. This is typically done once per year for most residential applications. No special tools are required. This type of neutralizer also acts as a filter removing sediment and small amounts of iron.Calcite MediaCalcite is a crushed and screened white marble media which can inexpensively be used to neutralize acidic or low pH waters to a neutral, less corrosive effluent.Calcite is a naturally occurring calcium carbonate media. One of the advantages of Calcite is that it will only dissolve until the water reaches a neutral pH. It does not over-correct under normal conditions. Upon contact with Calcite, acidic waters slowly dissolve the calcium carbonate to raise the pH which reduces the potential leaching of copper, lead and other metals found in typical plumbing systems. Periodic backwashing will prevent packing, reclassify the bed and maintain high service rates. As the calcium carbonate media neutralizes the water, it will increase hardness and a softener in some rare cases becomes necessary after the neutralizing filter. However this is unusual and only occurs on water that is very low in hardness and alkalinity. Most homeowners rarely find they need a softener. Calcite can be effectively combined with Clack Corosex to combine the high flow neutralization properties of Corosex, along with the slower reacting low flow properties of Calcite, increasing the ability to correct low pH.How to Install Calcite Neutralizer FiltersCalcite neutralizer filters are easy to install. They need to be located in the piping after the pressure tank on a well water system, but before the copper household piping. If the pressure tank is piped with copper, it is best to remove any copper piping before the neutralizer and replace with PVC, PEX, or stainless steel piping, in order to avoid the corrosive effects of the acidic water.Neutralizer filter tanks for home water systems typically measure 10 or 12 inches in diameter and 48 to 54 inches in height. The tanks have a center tube about 1 inch in diameter, called the distributor tube, which have a screen at the bottom of the tube. When the neutralizer tanks are assembled, the distributor tube is first placed in the tank and some tape or a cap put on the top of the tube to prevent media or gravel from entering the tube when the filter is built. Approximately 10 to 20 pounds of aquarium gravel 1/4 inch in diameter is first poured into the tank to cover the bottom distributor screen. The calcite media, which looks like white sand, is then poured in until the depth of the media reaches about two-thirds of the tank.The top one third of the tank is left as free space. This free space allows the media to expand when the neutralizer is backwashed. Neutralizer filters need to be connected to a drain to allow the filters to backwash. The backwashing is done automatically based on a simple timer typically once every one to two weeks. This flushes out any sediment or iron that the neutralizer filter has trapped and keeps the calcite clean and properly settled so it can filter and raise the pH in an optimum manner.Up-Flow Neutralizers An effective neutralizer filter uses an automatic backwash control valve, which allows the owner to have the neutralizer tank be automatically cleaned every one to two weeks. In some cases, no backwash control valve is used and instead of the water first flowing down through the media and up the distributor tube, the piping is installed so the water flows down the distributor tube and up through the media. This is called an “up-flow neutralizer” and they are not backwashed. There are some disadvantages to up-flow neutraliers despite the lower costs. In some cases calcite media can wash out of the neutralizer and enter the home water piping system causing damage. If the water flow is not sufficient the media can become solidified in places, causing the water to bypass the media.

Bangladesh security tightened following Pilkhana massacre and Bashundhara City fire

Friday, March 20, 2009

Following the Pilkhana massacre which occurred February 25 and 26 leaving 74 dead and the inferno at the Bashundhara City shopping mall complex March 13 leaving seven dead, Prime Minister Sheikh Hasina said security measures are being tightened countrywide across Bangladesh.

Fire drills will be enacted at all key-point installations (KPI). Fire fighting systems will be examined by the fire brigade and the public works department (PWD) to ensure functionality. Security measures will be enhanced supplementing areas under private security such as at the Bashundhara City Complex.

The Fire Service and Civil Defence Department requires modernization and needs new equipment to fight fires past the sixth floor of buildings. The Fire Brigade says it needs turntable ladders, snorkels, foam-tenders, lighting units, emergency tenders, fireproof uniforms, and rescue ropes for fire fighting and rescue operations. Transportation to fires is also an issue due to narrow roads, low electrical wires and congestion.

The Bangladesh National Building Code requires fire fighting equipment installed in buildings over seven floors. This code is to be monitored by authorities to ensure compliance with the new guidelines and to make sure buildings are being maintained.

The Bashundhara City Complex opened Monday for shoppers two days after Friday’s blaze. A probe is underway to determine the cause of the fire and to assess structural damage.

Loss of life was minimized as the blaze broke out on a Friday, the beginning of the weekend in Bangladesh, so offices in the upper floors were empty. The lower eight floors are used for shopping and the upper floors are all Bashundhara Group offices.

The mall is valued at Tk 7.0 billion (US$100 million). It is not known if the complex is covered by fire insurance.

It is estimated that it will take over two years to rebuild the area damaged by flames which were burned down to a skeleton. Bashundhara City’s technical advisor, Latifur Rahman, estimated damages at Tk 2.0 billion (US$29m).

Only one television cameraman has been allowed in to film the burnt area. None of the 2,500 shops, cinemas or cafes were burnt by the inferno. The seventh and eighth floors still experience smoke damage, and there was water damage to merchandise.

A three member committee is currently investigating the cause of the fire which will consist of Iqbal Khan Chowdhury, joint secretary of the ministry, representatives of the police, IGP Noor Muhammad, and fire brigade, Director General Abu Nayeem Md Shahidullah. The committee is required to report within the week with their findings. The forensics department is also sifting through the burnt remains.

The Dhaka Chamber of Commerce and Industries has also formed a committee which has begun interviewing witnesses and recording their testimony alongside the government committee.

It has been discovered that 150 closed circuit cameras were not being used when the fire started. Another mystery is why the mall fire fighting system has been found unused.

Why the fire burnt so fiercely is a matter to think….These matters seem to be mysterious

“In the shopping mall there is an ultra-technology elevator which runs even without electricity but we have found that locked,” Iqbal Khan Chowdhury, joint secretary (Police) of the home ministry, said. “Why the fire burnt so fiercely is a matter to think. We have to see if there was any incendiary substance there. These matters seem to be mysterious.”

Mall management has been asked to submit substances and items which would have been in the upper floors when the fire started. The fire erupted on the 17th floor and spread quickly to the two floors above and engulfed the three floors below. The aerial ladders belonging to the Fire Service and Civil Defence reached as high as the 13th floor of the 21-storey building.

Videos have been sent to the United States (US) for examination to assist in determining the cause of the fire and to help in the damage assessment. Experts from the US are expected to arrive soon.

Firefighters were brought to the rooftop of the 20-storey tower by helicopter. The only fatality in this operation was Baki Billa, a firefighter of Bashundhara City firefighting department, who fell when climbing down a rope from a helicopter to the roof of the building. Three other firefighters made the transition safely. At this same time, the chief security officer was safely rescued by the Bangladesh Air Force helicopter, a Bell 212. Six security officers of the complex also lost their lives.

Migrant workers in Dominos Pizza ‘slavery’

Friday, August 10, 2007

Eight Hungarian migrant workers sacked from a Domino’s Pizza franchise in Derby, England are said to have taken home virtually no pay for months because of illegal deductions.

The claim is refuted by the company who said in a statement “We have begun a thorough investigation during which we have scrutinised the franchisee’s employment practices. This took place with his full co-operation. The franchisee concerned is confident that he possesses the evidence required to refute these allegations. To the extent that we have been informed of all allegations and have reviewed all available evidence, we also believe this to be the case.”

The sacked workers are being supported in their claim by the workers union Unite. The union say the “there appeared to be a deliberate strategy of keeping the workers in debt to the company through a series of crippling deductions. The deductions included payments to cover the contract purchase of a car from their employer, insurance for the vehicle provided through their employer, and exorbitant rent for substandard accommodation, again provided through their employer. In addition, some workers had to pay fees of up to £180 for an “introduction” to the company. One worker earned just £5 in four months because of the constant and hefty deductions out of his wage packet. When the workers protested they were sacked.”

Puerto Rico power company cancels US$300 million Whitefish contract

Monday, October 30, 2017

At the request of Puerto Rico Governor Ricardo Rosselló, the Puerto Rican Electric Power Authority (PREPA) yesterday announced it has cancelled a US$300 million contract with a Montana-based company called Whitefish Energy Holdings amid concerns it may have been awarded improperly and the prices may be unusually high. Whitefish was to have rebuilt parts of the United States commonwealth’s energy infrastructure, which was recently destroyed when Hurricane Maria struck the island.

According to Whitefish spokesperson Chris Chiames, Whitefish was “very disappointed” and may consider a lawsuit. He also said about 350 Whitefish employees have been working on Puerto Rico for the past month, and their efforts will restore power to much of San Juan soon. He noted, “We will certainly finish any work that [PREPA] wants us to complete and stand by our commitments.” According to Governor Rosselló, Whitefish has already been paid eight million dollars.

The U.S. Federal Emergency Management Agency (FEMA) questioned whether the prices negotiated were reasonable and how Whitefish came to be awarded the contract. Whitefish is two years old, when the contract was signed only two people worked for it full-time, and it has connections to the current U.S. Secretary of the Interior. According to PREPA head Ricardo Ramos, FEMA approved the Whitefish deal, but FEMA officials said they did not.

Whitefish is based in the town of Whitefish, Montana, the hometown of Ryan Zinke, who is currently serving as U.S. Secretary of the Interior in the administration of the US President Donald Trump. Zinke and Andy Techmanski, Whitefish’s chief executive, are acquaintances, and Zinke’s son worked for Whitefish one summer. The founder of one of Whitefish’s financial backers, HBC Investments, has made nontrivial campaign contributions to Republicans and specifically to Trump.

Zinke told the public, “I had absolutely nothing to do with Whitefish Energy receiving a contract in Puerto Rico[…] Any attempts by the dishonest media or political operatives to tie me to awarding or influencing any contract involving Whitefish are completely baseless.”

Zinke also posted online, “Only in elitist Washington DC would being from a small town be considered a crime.”

The head of the U.S. House of Representatives natural resource committee, Republican Rob Bishop, has sent PREPA a letter requesting documentation of the deal and an explanation of the means by which it was made.

Maria Cantwell, a Democrat serving on the Senate Committee on Energy and Natural Resources called for “an investigation to determine how we got into this situation in the first place,” saying “taxpayers should pay a fair rate for the emergency repairs Puerto Rico desperately needs, […] not be gouged by Whitefish Energy or anyone else.”

According to the Associated Press, in one copy of the Whitefish contract, each employee would be paid a US$80 food allowance each day, and US$1000 each time they fly to or from the mainland U.S., with hourly pay rates for foremen, linemen and mechanics in the hundreds of dollars.

The federal control board in charge of Puerto Rico’s finances recently said they had appointed retired Air Force Colonel Noel Zamot to oversee the restoration of Puerto Rico’s power infrastructure, but Governor Rosselló said Puerto Rico’s own government is responsible for the power company, which has debts in the billions.

The category 4 Hurricane Maria struck Puerto Rico several weeks ago with high winds and intense rain. About 70% of Puerto Rico still has no electricity.

Puerto Rico was colonized by Spain and came under U.S. control in the Spanish-American War in 1898, along with Guam and the Philippines. Every person born in Puerto Rico is a United States citizen by birth. Puerto Rican residents do not participate in national elections, and have a non-voting representative in the U.S. congress. Mostly, they are exempt from federal income tax but not other federal taxes.

Rio Tinto Group, the world’s third-largest miner, say they will return a record annual profit of over AU$5.32 billion to shareholders, following surging commodity prices – doubling the group’s profit. Earnings from operations jumped 118 percent last year.

The London-based company unveiled a net profit of 58 per cent on the previous year. The result was boosted by increases in commodity prices driven by demand from China. Chinese interests account for around 15 percent of Rio Tinto’s sales.

Rio Tinto’s CEO, Leigh Clifford said demand for iron ore remains strong. Prices for the steelmaking raw material and metalshave climbed to records amid rising demand from China.

“China clearly continues to have a major impact on what they are doing,” said Tim Barker at BT Financial Group. “With commodity prices as strong as they are at the moment, and not showing any signs of a change of direction, one would think there is still room for some improvement in earnings in 2006,” he said.

The company produced 65 million tons of iron ore in the second half, 15 percent more than a year ago. Rio and other miners last year secured a record 71.5 percent price increase.

Rio Tinto say they are studying further mine expansion and will invest around $9 billion to meet the global demand led by China. Projects include expanding WA iron ore mines, its coal mine in NSW and copper interests in the USA.

Other investments would see the expansion of a titanium dioxide project in Madagascar and Canada, in the Cortez Hills gold venture in the USA, and in the Argyle Diamonds underground mine development in North West Australia.

In the 18 months since Andrea Muizelaar was crowned winner of the reality TV series Canada’s Next Top Model, her life has been a complete whirlwind. From working in a dollar store in her hometown of Whitby, Ontario, to modeling haute couture in Toronto, she had reached her dream of becoming a true Top Model.

But at what cost? Unknown to casual television viewers, Muizelaar had been enveloped in the eating disorder anorexia nervosa, which inevitably became too much for her to bear. She gave up modeling and moved back to Whitby, where she sought treatment for her disorder, re-entered college, and now works at a bank. Where is she now? Happy and healthy, she says.

Recently Andrea Muizelaar sat down with Wikinews reporter Mike Halterman in a candid interview that stretched to nearly two hours, as she told all about her hopes and aspirations, her battle with anorexia, and just what really happened on Canada’s Next Top Model.

U.S. Representative Patrick J. Kennedy (DRI), son of Massachusetts Senator Edward Kennedy, was involved in a traffic accident near the U.S. Capitol in Washington, D.C.

Capitol Hill Police reported that Kennedy was alone his 1997 Ford Mustang when the accident occurred Thursday at about 2:45 a.m. EDT (0645 UTC) near the 100 block of C Street SE. Police say his eyes were red and watery, and he was unbalanced and had slurred speech. Police also say that Kennedy had received three “notices of infractions” that are connected with the crash.

According to the police report, Kennedy drove his car into a security barrier near the Capitol building. When questioned by the police, he told them that he was “headed to the Capitol to make a vote,” when no votes were scheduled for that time of the morning.

Kennedy said in a written statement that he had returned home around midnight and had taken the sleep aid Ambien and the anti-nausea drug Phenergan, both of which are known to cause drowsiness and sedation. He awakened a couple hours later and was “disoriented” when the incident occurred. He also said that “at no time before the accident” did he take alcohol, and pledged to cooperate in any investigation.

Today, Kennedy said, “Apparently, I was disoriented from the medication” and that he “never asked for any preferential treatment.” He also announced that he is checking himself into the Mayo Clinic in Rochester, Minnesota.

“I know I need help. As in every recovery, each day has its ups and downs.,” added Kennedy. This is not the first time Kennedy has been to the Mayo Clinic. Last Christmas, Kennedy spent time at the clinic and went back to work after he was “feeling focused and in good shape.”

However; Robin Costello, spokeswoman for Kennedy said, “we have no knowledge of any citations,” but she did admit that a report was filed.

Capitol Police have not commented on the report or allegations, but Sgt. Kimberly Schneider, Capitol Police spokeswoman did say, “The United States Capitol Police are continuing to investigate.”

It is not known whether any sobriety test or arrest was made. Kennedy was not injured.

Apple Inc. today has introduced the much-anticipated iPhone at the Macworld Conference in San Francisco.

The iPhone is claimed to be “a revolutionary mobile phone” as stated on the Apple website. The device appears to be running a mobile version of the Apple operating system Mac OSX. It is approximately the same size as a 5th generation iPod, it has a 3.5-inch LCD touchscreen display that is used to access all features of the phone including number dial, as well as making phone calls. The iPhone plays music, movies, displays pictures and is able to connect to a wireless network.

Apple CEO Steve Jobs unveiled the device by walking onto the stage and taking the iPhone out of his jeans pocket. During his 2 hour speech he stated that “Today Apple is going to reinvent the phone, We are going to make history today”.

Today Apple also released their Media Center device – Apple TV. It will directly compete with Microsoft’s Media Center operating system. Apple has taken a different approach to the media center market; rather than storing content (such as movies, music and photos) on the device, Apple TV connects to a computer (Mac and Windows) over a wirless network connection and plays all content stored on that computer. This makes it substantially easier for users to organize their media content.

The Icelandic internet bank, Icesave, has suspended all 300,000 of its UK customer accounts, leaving account holders in the United Kingdom unable to withdraw or deposit any funds. A message on its website posted this morning states:

“We are not currently processing any deposits or any withdrawal requests through our Icesave internet accounts. We apologise for any inconvenience this may cause our customers. We hope to provide you with more information shortly.”

The internet bank, owned by the Icelandic bank, Landsbanki (Landsbankinn), which was recently nationalised in an attempt to rescue it, has been hit by the global financial crisis. Reports from the United Kingdom suggest that the traders and city are preparing for the parent company to be declared insolvent, leaving customers to recover their monies through a financial compensation scheme being backed by the Icelandic Government. The plan will cover the first € 20,887 (Approx £16,300 / $28,720), the remainder of the customers funds being recovered through the UK’s own financial compensation system.

Following the decision to nationalise Landsbanki, the Icelandic Prime Minister, Geir Haarde, who introduced and signed the emergency legislation into law, stated:

“What we are doing here is saving a banking system – saving the domestic banking system – and making sure that it can function properly. And I think, also, through our declaration on domestic deposits in these banks and saving institutions, we have been able to avoid a run on the banks here, and therefore prevent it.”

In describing and explaining its actions in nationalising the bank, the Icelandic Financial Supervisory Authority issued this brief statement:

“Based on new legislation, the Icelandic Financial Supervisory Authority (IFSA) proceeds to take control of Landsbanki to ensure continued commercial bank operations in Iceland. Domestic deposits are fully guaranteed, as declared by the government. Landsbanki’s domestic branches, call centres, cash machines and internet operations will be open for business as usual.”

In response to the deepening world financial situation, the Dutch government has this afternoon increased its savers protection from €38,000 to €80,000 effective immediately, to help secure the financial status of its savers within Holland. Icesave also has a Dutch branch, icesave.nl – their website was unreachable at the time of this article.
