+86 15936525232Clogged Drip Emitters: Sediment, algae and suspended solids in irrigation water will damage precision irrigation systems, resulting in uneven water supply, crop loss and high maintenance costs.
High Maintenance Cost & Water Waste: Manual filter cleaning is time-consuming and labor-intensive. Poor water quality also leads to resource waste and lower irrigation efficiency.
Risks of Unstable Water Quality: Turbid water corrodes water pumps, valves and pipelines, shortening equipment service life and raising operating costs.
Excellent Filtration for Complex Water Quality Adopting deep-layer quartz sand media, it removes sediment, organic matter and algae via physical interception and adsorption. It consistently supplies clean water and fully protects your irrigation system from clogging.
Automatic Backwashing with Zero Downtime The dual-tank structure enables one tank for filtration while the other for backwashing. No need to suspend irrigation or conduct manual disassembly and cleaning. The PLC control system ensures continuous operation and greatly cuts labor costs.
Sturdy Structure & Long Service Life Built with anti-corrosion carbon steel, the filter resists harsh outdoor conditions and high water pressure. Its robust construction guarantees years of stable performance with minimal wear.
Low Operating Cost & High ROI
Quartz sand media is cost-effective and easy to replace, with a service life of 3 to 5 years.
The equipment features low power consumption and no expensive consumables, keeping running costs to a minimum.
It effectively prevents emitter clogging, pump damage and water waste, helping you save a great deal on maintenance and resources.
Eco-Friendly & Sustainable No chemicals are added during filtration, so the treated water is harmless to crops, soil and the surrounding environment. It also improves irrigation efficiency to reduce water consumption, supporting sustainable agricultural development.
Flexible Configurations for All Scales Available in single-tank, dual-tank and multi-tank (2–6 tanks) parallel setups, suitable for small farms, large agricultural bases and industrial facilities. Custom sizes and flow rates are available to meet your specific requirements.
Agricultural Irrigation: Protect drip, sprinkler and micro-irrigation systems against emitter clogging.
Industrial Water Treatment: Pre-filtration for process water and wastewater.
Landscaping & Golf Courses: Provide clean water for large-scale sprinkler systems.
Municipal Water Supply: Pre-treatment for surface water sources.
