SLOT's Innovative Wedge Wire Screen Solution Sets New Benchmark for Water Efficiency in Large-Scale Agricultural Irrigation

A large farm in the North China Plain has long faced serious challenges with high sand content in well water and frequent screen clogging. When using traditional perforated screens, the system required 6-8 shutdowns for cleaning annually, significantly impacting irrigation stability and crop growth requirements. This issue not only increased maintenance costs but also directly threatened the farm's production efficiency.
SLOT Solution
Addressing this challenge, SLOT provided an innovative solution using 316L stainless steel wedge wire screens. The screen features a unique V-shaped slot design with 0.5mm precision, achieving a "narrow-outside, wide-inside" gradient filtration effect. This design increases the open area to 35% while maintaining 80Bar crushing strength, ensuring both filtration accuracy and product durability.
Implementation Results
After a complete irrigation season of operation, SLOT's wedge wire screen demonstrated exceptional performance. The effluent sand content was significantly reduced from 15% to 0.5%, a 97% improvement; single well yield increased from 50m3/h to 75m3/h, a 50% increase; most notably, annual maintenance was reduced from 8 times to zero, achieving 100% maintenance cost reduction. These data fully demonstrate the effectiveness of the solution.
Client Feedback
Project Manager Zhang commented: "SLOT's wedge wire screens not only completely resolved the long-standing clogging issue but also improved irrigation system reliability by 90%, saving us RMB 120,000 annually in maintenance costs. This investment has delivered returns far exceeding expectations."
Technical Advantages
The success of this solution stems from three core technical advantages: first, the anti-clogging design with V-shaped wires effectively prevents particle jamming; second, the long-life material with 316L stainless steel offers excellent chloride corrosion resistance; finally, the customization capability allows SLOT to deliver non-standard sizes within 7 days.
Industry Application Expansion
Building on success in agricultural irrigation, SLOT has expanded this solution to mine dewatering and municipal water supply sectors. Remarkable results have been achieved in projects including an Inner Mongolia coal mine drainage system and a water plant in Jiangsu province, with over 200 wells successfully deployed worldwide to date.
