Tekleen Water Filter
Though seldom part of the original design, irrigationsystems need filtration to rid contaminants from the lines. This ensures thatplants are being watered properly and reduces the frequency of irrigationsystem maintenance by preventing small particles from progressing through thenozzles to plants.
“Filtration is a must with drip systems,” saysGideon Brunn, president of Automatic Filters Inc. “Otherwise, the nozzlesare constantly clogged.” Tekleen Water Filters take the maintenance outof the process because they are self-cleaning.
The line pressure at the filter outlet drops after dirtsettles on the screen. As the pressure reaches a pre-set differential, ittriggers the backwash cycle to begin. The vacuum nozzles suction dirt from theinside of the screen and flush it out into the drain. All of this is donewithout interrupting the main flow and requires only two gallons of rinsewater, making it both production- and environmentally-friendly.
“You are not flooding the area with a lot of backwashwater like a lot of other filters. For example, a 2-inch filter would use twogallons of water per rinse. Other filters with a 2-inch flushing valve woulduse 20-30 gallons of water,” explains Brunn.
Installation is simple — attach the filter to the lineand turn it on. Aldridge Nursery, Von Ormy, Texas, purchased three additionalTekleen filters after being so impressed with its first one. Its oldest filterwas purchased in 2000 and has not needed any upkeep. “We did some thingswhen we first got it that we thought we needed to do, like take it apart andclean it, and we found out it wasn’t necessary,” says RalphSimnacher, owner. “We thought we knew more than the instructions.”
Ulery Greenhouse, Springfield, Ohio, has had the filter forabout 1 1/2 years, with no major problems. “They only thing you have todo is change the battery in it once a year, because it automaticallybackflushes,” says Ashley Smith, grower.
The only required maintenance is to keep an eye on it.”To make sure the machine is functioning correctly, you have to make surethat you monitor your inlet and outlet pressures. Make sure that the flushingsystem is working correctly. It’s fully automatic, but you should keep aneye on it to make sure that it’s properly working,” says RickRuggeri, part owner of Silver Terrace Nursery in Pescadero, Calif.
Silver Terrace Nursery uses three Tekleen filters to back upthe sand filters at the reservoir that serves as the nursery’s main watersupply, and they report no problems to date. “We haven’t had tomaintain them up to this point,” says Ruggeri. One thing Silver TerraceNursery did decide to do was to take out the battery and use 110-voltcontrollers. “So they’re basically self-sufficient, and youdon’t have to mess with a battery,” Ruggeri says.
With advance notice, Automatic Filters can provide filtersthat are pre-fit for controllers. Options include 220-, 110-, 12- and 9-voltcontrollers. Automatic Filters Inc., Los Angeles, Calif. (310) 839-2828.
