Principle of conservation When the plant’s 20-year-old filter needed replacing last year, one major concern was that the new filter operate on a small amount of electricity.“We try to conserve as muchelectricity as we can in addition to conserving the amount of potable city water that we’re using,” said Mike Wagner, operations manager. Wagner’s search for the perfect filterled him to two choices, after which a cost comparison narrowed it down to the Tekleen water filter manufactured by Automatic Filters in Los Angeles.“The Tekleen filter uses 110 currentfor the control box and no motorized parts, so we cut down our electrical usage from before,” says Wagner.Although the actual dollar savings mayamount to only about $50 per year, “it’s the principle of conservation that counts,” he said. According to the manufacturer, theTekleen self-cleaning filters require very little maintenance.As particles collect on the screen, theoutlet pressure drops. When the pressure reaches a preset differential, the backwash cycle begins. Within 10 seconds and without interrupting the main flow, vacuum nozzles aggressively suction the dirt from the inside of the screen.The Watsonville Wastewater TreatmentFacility currently pumps 400 gallons per minute through the filter installed with a 200-micron screen.“The filter is working very well,” saysWagner, “and we’ve received very good service from the company.”Tekleen filters are produced byAutomatic Filters, Inc., a Los Angeles- based company that specializes in industrial and irrigation filtration systems. Tekleen filters have been recognized as the industry’s highest quality self-cleaning water filters. For more information, call 310 839 2828 or visit www.tekleen.com.

Watsonville, Calif. incorporates automaticfilter to recycle treated wastewater

Tekleen Self Cleaning Water Filter in Waste Water - 27095 S

ituated in the heart of theMonterey Bay area in the lush Pajaro Valley, the city of Watsonville lies 95 miles southof San Francisco at the southern end of Santa Cruz County.Long before the federal governmentdedicated the pristine Monterey Bay as a National Marine Sanctuary, the Watsonville Wastewater Treatment Facility was serving as a first line of defense in protecting theBay's precious water quality.First constructed during the 1920s, theWatsonville Wastewater Treatment Facility has seen its mission grow from servicing a small agricultural community to treating wastewater for as many as 50,000 residents, treating an average daily flow of seven million gallons of wastewater originating from residential, commercial and industrial sources.Always a friend of the environment,the Watsonville Wastewater Treatment Facility makes a conscious effort to conserve natural resources.Accordingly, the treatment facility usesits own treated wastewater for general plant purposes such as washing and cooling rather than consuming fresh water from the city.Although Watsonville’s wastewater istreated to the advanced secondary treatment level, and undergoes extensive monitoring and testing to ensure compliance with all state and federal pollution prevention laws prior to being discharged to the Monterey Bayover a mile off shore, it must be filtered before it can be used for plant washdowns and cooling.Otherwise, the accumulationof solids such as algae would clog machinery and make such recycling impossible.
