The High-Efficiency Sand-Water Separator is designed to efficiently remove sand, grit, and other heavy inorganic particles from wastewater during the pre-treatment process. By combining gravity sedimentation with a shaftless screw conveyor, the system delivers continuous solid-liquid separation while improving overall treatment efficiency.
The separator features a shaftless spiral conveyor and high-performance gear reducer, ensuring stable operation with minimal clogging and low maintenance. Separated grit is continuously discharged, while clarified water flows back into the treatment system for further processing.
Constructed from corrosion-resistant stainless steel, the equipment is built for long-term operation in demanding wastewater treatment environments. It is widely used in municipal wastewater plants, industrial wastewater treatment systems, food processing facilities, chemical plants, and paper mills.
By effectively removing abrasive particles at the beginning of the treatment process, the system protects pumps, pipelines, and downstream equipment, reduces maintenance costs, and extends equipment service life.
Our engineering team has meticulously refined every aspect of this sand-water separator to solve the most pressing challenges in modern wastewater management. By partnering with a reliable supplier, you gain access to features designed for longevity and supreme performance.
Advanced Drive Mechanism: Equipped with the latest shaft-mounted reducer, the machine operates with a highly compact structure. This eliminates the need for bulky couplings, ensuring a smooth, vibration-free operation that significantly extends the lifespan of the motor.
Waterless Bearing Design: By completely removing underwater bearings from the architecture, we have eradicated one of the most common points of failure in traditional separators. This means zero underwater corrosion and zero need for submerged lubrication.
Whisper-Quiet Operation: The integration of a flexible wear-resistant liner within the U-shaped slot dramatically dampens the acoustic output. Operators will experience a noticeably quieter working environment, free from the harsh scraping sounds of metal on grit.
Effortless Maintenance: The lightweight construction and quick-fitting liner design mean that when routine checks are necessary, your maintenance crew can perform them swiftly without heavy lifting equipment or specialized tools.

To assist your procurement and engineering teams in their evaluation process, we have compiled answers to the most common technical inquiries regarding our solid-liquid separation machine.
The shaftless design eliminates the central axis, which is the primary point where fibrous materials and sticky sludge tend to wrap and accumulate. This open-center architecture allows high-viscosity materials to be conveyed smoothly without causing mechanical blockages, ensuring continuous, unattended operation.
While the exact lifespan depends on the abrasiveness and volume of the incoming grit, our high-grade flexible liners are engineered to last significantly longer than traditional rigid steel liners. Under standard municipal wastewater conditions, they provide years of reliable service and can be replaced quickly to minimize downtime.
The equipment is designed to operate optimally at an installation angle between 20° and 30°. While the specific angle is typically determined during the manufacturing phase based on your civil engineering drawings, minor adjustments can be accommodated during installation using the flexible support brackets to ensure a perfect fit.
No, the separator is designed to utilize the incoming wastewater mixture for its separation process. The axial shift mechanism effectively drains the free water back into the system while pushing the relatively dry sand upward, completely eliminating the need for an external flushing water source.
The drive device, featuring the advanced shaft-mounted reducer, is strategically positioned at the highest point of the equipment, well above the maximum water level. This top-mounted configuration, combined with high-grade industrial sealing, completely isolates the vital electrical and mechanical components from moisture, accidental splashes, and corrosive gases.
