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.
