The Automatic Shallow Sand Filter provides reliable water filtration through intelligent automatic backwashing and modular filter tank design. The system continuously removes suspended solids while minimizing maintenance requirements, making it an ideal solution for industrial water treatment and large-scale irrigation systems.
The Automatic Shallow Media Filter is designed to provide reliable filtration for industrial and municipal water treatment systems. By combining shallow filtration media with intelligent automatic backwashing, the system efficiently removes suspended solids while maintaining stable hydraulic performance.
Its modular vessel configuration and compact footprint make it particularly suitable for projects requiring high flow rates, continuous operation, and easy maintenance.
Technical Highlights
Shallow Media Technology
Short filtration depth improves cleaning efficiency while maintaining excellent particle removal performance.
Automatic Sequential Backwash
Each vessel is cleaned independently without interrupting the filtration process.
Low Hydraulic Resistance
Optimized internal water distribution minimizes pressure loss and reduces pumping energy consumption.
Reliable Construction
Available in carbon steel, SS304, or SS316L with corrosion-resistant coatings.
