The LSF Sand-Water Separator is designed for:
Urban Sewage Treatment Plants: Integrated with cyclone grit degreasing tanks or bridge-type sand suction machines.
Grit Tank Processing: Separates sand-water mixtures discharged from preliminary treatment systems.
Municipal Infrastructure: Ideal for wastewater facilities requiring efficient grit removal and dewatering.
Shaftless Screw Design:
The sand-water mixture enters from the top of the separator.
Grit settles by gravity in the U-shaped separation tank.
Efficient Transport:
A shaftless screw rotates at ≈4.8 r/min, moving grit along the 25° inclined trough toward the discharge outlet.
Separated grit falls into a collection barrel for disposal.
Water Discharge:
Clarified water overflows from the tank’s top, reducing environmental impact and simplifying transport.
High-Efficiency Drive:
Shaft-mounted helical gear reducer ensures compact, stable, and safe operation.
Superior Performance:
Recovers ≥96% of particles ≥0.2mm with post-separation water content <65%.
Durable Construction:
U-shaped trough lined with wear-resistant material extends service life and simplifies maintenance.
Closed-Loop System:
Fully enclosed design improves hygiene and reduces odor.
Frame secured with expansion bolts (no embedded parts required).
Flexible Control:
Compatible with central automation systems or optional local control boxes.
Proven Reliability: Optimized for 24/7 operation in harsh wastewater environments.
Low Operating Costs: Energy-efficient motors (0.37–0.75 kW) and minimal maintenance.
Regulatory Compliance: Meets municipal wastewater treatment standards for grit removal.
Quick Installation: Pre-assembled components reduce on-site labor.
We offer tailored solutions based on:
Flow rate requirements (5–35 L/h).
Integration with existing grit removal systems.
Material upgrades for corrosive environments.
