Sand Media Filter – Reliable Primary Filtration for Agricultural Irrigation
Shandong Jintian's sand media filter is engineered for high-efficiency removal of suspended solids, organic matter, algae, silt, and fine particles from irrigation water sources.-Using hard, wear-resistant quartz sand as the filtration medium, this filter serves as the ideal primary filtration solution for surface water (rivers, streams, canals, reservoirs, ponds, and lakes) containing high loads of organic materials, silt, and clay.
How It Works:
The filtration process operates on the principle of depth filtration. Raw water enters from the inlet at the top of the tank and passes downward through a thick bed of uniformly graded quartz sand (recommended media size: 2–4 mm).-As water flows through the sand bed, suspended solids, algae, organic matter, and other impurities are trapped within the voids between the media particles.-Treated water then passes through the underdrain system and exits through the outlet, delivering clean, filtered water to the downstream irrigation network.-
Over time, accumulated debris increases pressure drop across the filter. To restore performance, the system initiates an automatic backwashing cycle: flow direction is reversed, fluidizing the sand bed and flushing trapped particles out through a dedicated drain, all without interrupting downstream water supply.
Key Features & Benefits:
-
High Filtration Efficiency – Three-dimensional depth filtration captures a wide range of contaminants, including organic matter, silt, sand, and suspended solids, protecting downstream drip emitters, sprinklers, and valves from clogging.-
-
Automatic Backwashing – Self-cleaning mechanism ensures consistent filtration performance, minimizes manual intervention, and maintains uninterrupted water supply during backwash cycles.-
-
Flexible Multi-Unit Configurations – Modular design allows single-tank operation or multi-tank parallel combinations to accommodate varying flow requirements from small farms to large-scale irrigation districts.-
-
Robust & Durable Construction – Heavy-duty carbon steel or corrosion-resistant materials, with UV protection and industrial-grade coatings, ensure long service life in harsh outdoor field conditions.-
-
Low Pressure Loss – Optimized internal hydraulics and media bed design maintain low head loss, reducing pumping energy costs.-
-
Adaptable Media Options – While quartz sand is standard for irrigation applications, alternative media (e.g., manganese sand, activated carbon) can be used for specialized water treatment needs such as iron or manganese removal.
