Water Filters

Analytical Technology (ATi) has introduced the innovative new C10/77 Particle Sensor, for the continuous on-line monitoring of particle counts in raw water, filter influent and filter effluent. Based on a laser light blocking principle, this novel sensor can provide particle count data over size ranges from two to 200 microns, with three 4-20 mA analogue outputs and an RS-232/485 digital output supplied as standard. ATi currently has over 75 of these monitors working in various water companies in the UK.

Turbidity monitoring of filtered potable water provides an excellent indicator of water clarity as well as a reliable measure of general filter efficacy.

Recent studies, however, indicate that particle count data can provide additional information concerning filter operation, and often can provide an early warning of filter breakthrough before turbidity values begin to rise.

Each C10/77 Particle Sensor from ATi contains an integral LED display used to indicate either raw count data or differential counts.

The user may select a display of the total particles about a certain size, or differential counts.

The display is operated from sealed membrane switches on the front unit.

Amiad Filtration Systems Ltd said it expects to report full-year results in line with market expectations, with revenues likely to increase by about 5 pct to just over 44 mln usd, compared to 42.4 mln in 2005.

The water filter firm said in a trading update that it experienced a recovery in the second half of the year, with revenues growing by close to 10 pct compared to a year ago, as it delivered its first water treatment project in Russia and began sales in India.

Thread filter sales, while still a small part of the business, look set to achieve ’significant growth’ this year, it said.

Burt Cohen, who has run a pottery studio, has developed ceramic water filters and hopes they will bring clean drinking water to people in underdeveloped countries, a January 24 article in The Morning Star reported.

The filter project is sponsored by Potters Without Borders, an international, non-profit group which aims to help stop waterborne diseases through its ceramic water filters. Cohen is one of its founding members and the principal director, the story said.

The filters remove E. coli, Giardia, cholera and Cryptosporidium and are made with clay and other materials, according to the article.

Cohen will not make filters, but wants to share the methods and information needed to make them, the article said.

Potters Without Borders, which was founded a year ago, has received numerous requests to set up ceramic water filter manufacturing overseas, the story said.

Gippsland residents are being warned to be wary of a scam involving water filters and false claims about the region’s drinking water.

Gippsland Water says a man is selling water filters by telling shoppers in Sale that effluent is about to be introduced into the region’s drinking water supply.

John Mitchell from Gippsland Water says the man is acting dishonestly to promote a product.

“We want to assure people that nothing like that has happened whatsoever, we have not put any treated effluent in the Sale water system or any other water system for that matter and we would not do that,” he said.

The Christchurch couple which invented a water filtration system for use by intetrnational aid agencies say they standing by their product despite tthe hospitalization of two journalists who tested it.

Four reporters from The New Zealand Herald, TVNZ and TV3 suffered serious stomach problems, with two of them requiring emergency treatment in hospital.

All four were covering the launch of Russell and Sue Kelly’s water filtration system which is designed to turn polluted water and raw sewage into drinking water.

Ms Kelly told Radio New Zealand the sample may have inadvertently become contaminated, but she stands by the effectiveness of the filtration system.

PLANNING bosses have given the go-ahead for a disused filter station on the edge of Ilkley Moor to be transformed into a home.

Despite objections and an alternative parish council plan to make the Wells Road building into a tourist visitor centre, members of the Keighley Area Planning Panel followed a recommendation by a planning officer to allow the Yorkshire Water plan.

The filter station used to treat spring water running off the moor but stricter laws governing drinking water quality rendered the station redundant.

A new kind of water cleaning equipment has been made in the Democratic People’s Republic of Korea (DPRK), the country’s official media reported Wednesday.

The magnetizing water filter, which “consists of filter bar, permanent magnet, air-tight gear and others,” was developed by the technical preparation center of the Electrical Machinery Industrial Management Bureau under the Ministry of Machine-Building Industry.

According to the official Korean Central News Agency (KCNA), this equipment can “completely” eliminate the pathogenic germ and provide clean water.

Furthermore, it is useful for prevention and treatment of “diseases in nerves, blood vessel and digestive system and skin,” said the KCNA, adding that it also has a special effect “for health and the prevention of aging.”

Pure drinking water, the most sought after commodity on the planet, could soon be within reach of millions of people thanks to the ingenuity of Kiwi Russell Kelly, backed by space age technology developed for NASA.

His recently designed filter system can turn sewage-polluted water into drinking water. International patents and trademarks protect the various processes.

Having lived in Kashmir on the India/Pakistan border, and having travelled widely through Asia, Kelly and wife Sue set about inventing a simple filter system that was portable, required low maintenance and that could be operated by gravity, bicycle power or a generator.

“We have also had 17 years practical experience in the water treatment business in New Zealand which assisted us in developing the necessary technologies that were efficient, robust and practical, and in most cases did not require electricity to achieve the goal. We were always confident in our ability to come up with the appropriate solution to the problems and knew what was required, but it has taken a long time to get there,” he said.

A water filter system designed by a Christchurch couple is being touted as a tool that can turn sewage-polluted water into drinking water.

Russell Kelly and his wife Sue, who have 17-years of experience in the water treatment business, have spent four years developing the filter system for third world countries.

Mr Kelly says NASA has given them the rights to use the iodine technology which it developed, and also given them approval to use NASA’s logo.

Russell Kelly yesterday put his water filter system to work, with a rough mix of foul water.

He collected water from the Avon River then “took some of the raw sewage from the Bromley sewerage and mixed it and I drank it, and several others did the same thing”.

The system has taken four years to develop.

Kelly and his wife, Sue, say they have had approaches for the system’s use from the nomadic Masai tribes via the Kenyan Government.

Pedal-powered, gravity fed, or generator-driven, his filter systems had no need for electricity, said Kelly.

Having lived in Kashmir on the India-Pakistan border, and having travelled widely through Asia, the Kellys came back to Christchurch to develop the system.
