Twin-Tank Sand Media Filter for Irrigation

Prepare pond, reservoir or canal water for crop irrigation with a twin-tank sand media filter arrangement. A media bed retains suspended material throughout its depth, making this type of filtration useful where organic debris places a heavy cleaning burden on a small screen filter. Choose the station around water quality and operating flow, including the water needed to clean the beds.

Two vessels and a shared pipe layout

The pictured assembly has two upright blue vessels, legs, upper horizontal pipes and a lower connection between the tanks. This layout needs a firm, level installation area and room around both vessels for servicing. Allow space for the connecting pipes, isolation valves and a safe backwash discharge route; do not size the installation from the pipe connection alone.

Plan filtration and backwashing separately

During filtration, irrigation water passes through the selected media before continuing downstream. Cleaning reverses flow through a bed to release collected material and discharge it away from the crop lines. Confirm the required backwash flow and pressure with the chosen tank size and media. Two tanks do not by themselves guarantee uninterrupted irrigation while one vessel is being cleaned; that depends on the manifold and valve arrangement.

Choose the configuration for your field

The listed connection range is 2 to 6 inches with a PN10 pressure class. Confirm the selected vessel dimensions, tank pressure limit and connection standard for the actual installation. Check whether filter media, backwash valves, controller and pressure gauges are supplied with your chosen configuration before ordering. Do not assume the photographed pipes include automatic control equipment.

Keep the drip network protected

Record pressure loss across the station and inspect the backwash discharge to assess cleaning. Follow the specified procedure before opening a vessel or servicing its media. For drip irrigation, select downstream screen or disc protection to meet the emitter maker's filtration requirement and help catch media that could escape the station. The filter removes suspended particles; it is not a treatment for dissolved salts.
