Quality Tank Construction: All tanks are constructed of high quality welded 304 stainless steel and designed for a 100psi operating pressure, where higher pressure is available as an option. Standard tanks are equipped with inlet and outlet connections, and top mounted loading port; tanks are also sandblasted form the inside and out.
   Underdrain: Hub and lateral distribution system is designed to utilize the entire bed area during operation. This minimizes channeling during periods of low flow. The underdrain is constructed of schedule 80 PVC laterals.
   Automatic Diaphragm Valves: To have a trouble free system, we design the ultimate water filter using a "Nest" of corrosion resistant diaphragm valves. The angular design, high lift, and large seat opening of the hydraulically operated valves provide a minimum restriction to flow. In a manual filter, a butterfly valve is used for backwash.
   Timer/Controller: The standard method of control for automatic units is a stager with and integral clock timer. The control has a built in manual override in case an off schedule backwash is needed.
