Filters

Filtration should be determined by the system flow rate, emission device, water quality, and system operation. The filter size will be determined by the system flow rate and load. The emission device determines the degree of filtration needed to prevent mechanical plugging (most drip and micro systems require a minimum of 120 mesh to 150 mesh). Water quality will determine the type of filter. Clean water will not require as much as a dirty water source. The filter should always be selected for the highest load during operation (time of year). Last the operation of the filter (manual vs automatic) will be determined by backwash frequency (how often filter needs to be cleaned) and system operation. Filters should be cleaned based on a pressure differential no greater than 8 PSI. This means when the inlet pressure is 8 PSI higher than the outlet pressure it is time to clean the filter. Media filters need to be set on a timed backwash as well as a pressure differential due to the nature of the filter media (no longer than 6 hours). We have an experienced staff to help with your filter selection.

Media Filters

The Modular Sand Media Filter is an advanced fifiltration system, designed from the ground up, especially for media filtration, to provide the ultimate Sand Media Filter.

Light Weight No Rust - Glass Filled Nylon and UVR PVC Construction Modular Design - 15-25GPM per Tank - Add as Many Tanks as Needed Minimal Back Flush Water - Individual Back Flush Valves Two Wire Back Flush Controller - 96 Station Back Flush Controller Pressure Switch Similar Foot Print As Existing Sand Media Tanks Back Flush Water Recovery System Available No Pressure Sustaining Valves Needed for Back Flush No Forklifts Needed - Easy Installation Only 5 Gallons of Media Per Tank Available with Groove Inlet / Outlet or Union Connections Supplied with Air Release Valves and Pressure Gauges

Fail-Safe type of filtration and easy to maintain. Use when source is an open body of water and (or) organics are present. Large surface area prolongs backwash cycles. Need at least two filter tanks to backwash with clean water. Can be used on well water or where excess amounts of sand are produced. Backwash the filters every 3-6 hours of operation (time interval) to prevent channeling of the media, or when there is a drop in the discharge pressure (pressure differential).
