OXNARD, CA, Oct. 4, 2005 -- Amiad Filtration Systems announced today it has been selected by the California/Nevada chapter of the American Water Works Association (AWWA) to present a formal paper at its Fall Conference being held Oct. 10-14 in Reno, Nev.
Amiad senior application engineer Dr. Marcus Allhands will present his paper: "From Flush to Lush: Water Reuse".
At the National Rural Water Association's Annual Technical Conference and Exhibition, Oct. 9-12 in Sacramento, he'll present his paper: "One step in the treatment of creative water sources in arid climates: a primer on pressurized filtration" on Wednesday, Oct. 12.

"Wastewater treatment plant effluent was once an expensive disposable problem," explains Allhands, regarding his "Flush to Lush" paper. "It is now a valuable asset at many locations in America. As a result, reuse of this water is growing rapidly."
In order to reuse WWTP effluent, two processes must occur: disinfection and the removal of suspended solids. Allhands will outline a number of technologies employed for both of these processes, demonstrating how laborious and energy intensive some of the solutions can be.
He will juxtapose those insights with application samples from California, Florida and Indiana where organic and inorganic suspended solids were removed from WWTP effluent using automatic, self-cleaning filters for reuse in the irrigation of vineyards, golf courses, landscape and residential lawns; as well as other applications, such as pump seal flushing, chemical makeup water and power generation cooling.
Allhands contends that automatic, self-cleaning filters remove a broader spectrum of particles than centrifugal separators, use less energy than granular media filters and require no costly labor associated with replacing filter elements, or shutting down the system during the cleaning cycle.
Following, he will present a review of pressurized filtration methods, including an in-depth textbook-style study of automatic self-cleaning screen filtration since this filtration method is quickly become a leader in the removal of suspended solids due to its small footprint, low water usage for cleaning and energy conservation.

"Rapidly growing populations and restricted water resources are problem conditions many areas of the country are facing today, explains Allhands, regarding his "Pressurized Filtration" paper. "As a result, new and innovative solutions or at least "stop-gap" measures are being derived by resource managers and municipal utilities everyday."
Allhands said his presentation aims to offer attendees a primer for addressing these needs. He noted that whether organizations are reusing WWTP effluent, storing for peak demand during off-peak hours or utilizing less-than-desirable supply sources, water treatment is of prime concern and filtration is invariably a step in the process.
Allhands says he will highlight some actual reuse and augmentation projects in the Western United States including a waste water treatment plant effluent reuse in California and a residential irrigation flow augmentation in Utah.
