Water Filter Prevents Clogged Sprinkler Heads

Monday 18 September 2006 @ 7:21 am

As with most golf courses, Atlantis Country Club in Tuckerton, N.J. was plagued with water quality problems. Providing irrigation water for the sprinkler system were two sources, a pond and a canal.

The water from both sources was highly contaminated with suspended solids, including silt, sand, leaves, etc. Due to the lack of filtration, a large number of problems resulted from clogged heads. Not only did this result in increased maintenance requirements, it could result in inadequate irrigation as well.

The solution was to install two ORIVAL self cleaning water filters, one on each pumping station. The filters, one 8 inch, which filters 1300 gpm and one 4 inch, which filters 350 gpm, were both provided with the standard control system OR-E-1, which provides regulation of the filter rinse cycles.

Automatic Self Cleaning Water Filter Makes Manual Filters Obsolete

Monday 18 September 2006 @ 7:01 am

TOYODA TRW is a major supplier of power steering pumps for the automotive market. We have only two downtime periods per year, so facility equipment has to run for six months with no interruption.

Contamination of the cooling water system was a continual problem, as anyone with cooling towers knows. Airborne particulate, microbiological growth, pollen, cottonwood and other materials collected in the cooling tower. Flowing through the pipes, the water picked up rust, iron chips, scale and other corrosion byproducts. Combined, these particles reduced the efficiency of our heat exchangers and machines. It was a full time job for one person to clean individual machine strainers, filters and heat exchangers.

We investigated several types of filtration equipment, including sand filters, centrifugal separators, motorized filters and, finally, the Orival filters. We wanted an automatic, self cleaning filter which requires no external power, is able to remove particles of any specific gravity, even lighter than water, does not interrupt system flow, requires minimal maintenance and offers the lowest operating cost. The Orival filter combines all of these qualities.

Our first purchase from Orival was a 4″ Model OR-04-PE, rated at 350 gpm and equipped with a 120 micron fine screen. We started up this unit with little assistance from the engineering staff at Orival. The filter was in operation for about 4 years, with absolutely no service requirements.

Schroeder Introduces Backflush Water Filter

Monday 18 September 2006 @ 6:59 am

Schroeder Industries, a recognized leader in filtration and fluid conditioning products, introduces the Backflush Water Filter (BWF) designed specifically for water-based fluids requiring backflushing capability.

The BWF is a dual stage filter ideal for extracting solid particles from low viscosity fluids. The system provides continuous filtration throughout the backflushing process, making it ideal for systems requiring continuous operation. Additionally, the filters require little maintenance, thereby providing an increase in efficiency and reduction in operating costs. The BWF boasts minimal pressure drop and is rated for 75 gpm up to 1000 psi.

The rugged BWF features brass construction, stainless steel elements, and a durable steel handle with locking mechanism control.

Nano water filter developed

Monday 18 September 2006 @ 6:58 am

The filter was more effective than others now available, said senior researcher Dr Ngo Quoc Buu.

Importantly, it worked at a very low pressure which also reduced the danger of its failing.

“The filter helps to refine colours in water much better than other filters,” he said.

Project manager Dr Nguyen Hoai Chau said a striking advantage of the nano filter was that is was not necessary to add a chemical or micro-organism to make it more effective.

Abattoir uses reed-bed water filter to save money and local wildlife

Monday 18 September 2006 @ 6:57 am

A Lancashire abattoir will save 4500 a week after creating 10 ponds and lagoons to purify its waste water.

Rose County Foods, part of the Irish meat processor Dunbia, put the bulldozers to work in over 8ha (20 acres) of land surrounding the plant to create a reed-bed water treatment system.

Last week saw the first of the company’s dirty water trickle into the primary lagoon as Environment Agency staff granted persmission for the process to start. In coming months more of the company’s waste water will be fed into the system.

Stan Ayrton of Rose County Foods, who has overseen the project, says he’s been amazed at the influx of birds and wildlife even though the water levels are still low.

3M sues over water-filter patents

Monday 18 September 2006 @ 6:56 am

3M Co., the maker of Cuno and Aqua-Pure water filters, sued units of Clorox Co. and Sears Holding Corp., accusing them of infringing two patents on a cartridge-based purification system.

3M, based in Maplewood, is asking for unspecified damages and an order blocking Clorox’s Brita Products and retailer Sears from selling products that violate the patents. The complaint, filed Aug. 31 in U.S. District Court in Minneapolis, also requests a jury trial.

The patents cover a water-filtering system that allows cartridges to be changed without drips. 3M, the maker of Post-It notes and Scotch tape, added water-filtration systems to its product line when it bought Cuno in August 2005 for $1.29 billion, the company’s biggest acquisition.
