Damage-Resistant Operation: The slow rotational speed ensures that any hard objects or debris entering the system will not cause structural damage to the screen or internal mechanisms.
Gravity-Assisted Dewatering: As the slag is transported upward, gravity naturally pulls excess water back into the channel, reducing the weight and volume of the final waste product.
Intelligent Flushing: Equipped with a grid frame flushing system meticulously controlled by a high-grade solenoid valve for precise water usage.
Facility managers understand that the lifespan of water treatment equipment is dictated by its resistance to harsh, corrosive environments. This machine is constructed with premium-grade materials designed to withstand continuous exposure to acidic, alkaline, and highly reactive industrial effluents.
Advanced Underwater Bearing: The system utilizes a specialized copper alloy sliding bearing for all submerged rotational points.
Self-Lubricating Technology: This unique bearing material slides effortlessly in water without the need for added lubricating oil, completely eliminating the need for hazardous underwater maintenance tasks.
Superior Wear Resistance: The structural integrity of the copper alloy prevents degradation from grit and sand, ensuring long-term stable operation and drastically prolonging the overall service life of the unit.
Protecting expensive downstream equipment, such as MBR membranes and high-pressure pumps, is the primary goal of any initial screening phase. This unit delivers exceptional precision, ensuring that microscopic threats to your infrastructure are neutralized at the intake.
Micro-Gap Customization: Available with ultra-fine grid gaps ranging from 0.5mm to 5mm, allowing operators to tailor the filtration level exactly to their specific effluent profile.
Maximum Interception: Highly effective at capturing notorious troublemakers like short fibers, hair, plastics, and floating scum that typically bypass standard bar screens.
Elite Separation Rate: Through advanced fluid dynamics and mesh design, the solid-liquid separation efficiency consistently reaches over 97%, guaranteeing a pristine output for secondary treatment stages.
Flow Rate Stability: Maintains a steady flow rate of approximately 1.0m/s, preventing bottlenecks and backups in the intake channel.
Screen clogging is a universal pain point that drains labor resources and threatens plant overflows. We have engineered a comprehensive self-cleaning ecosystem within the drum that operates autonomously, freeing your workforce for more critical tasks.
As the drum rotates at its fixed, deliberate speed, heavy-duty nylon brushes mounted on the interior continuously sweep the mesh surface. This physical brushing is paired with a high-pressure flush water spray nozzle located above the drum. Together, they dislodge stubborn dregs and immediately export them via the spiral lifting mechanism. Because the system cleans itself dynamically during operation, the screen net remains permanently unblocked, ensuring consistent hydraulic throughput without a single moment of manual intervention.
Space is a premium commodity in any industrial or municipal facility. Traditional setups require separate machines for screening, conveying, and pressing, leading to massive footprints and complex electrical routing. This equipment revolutionizes plant layouts by combining four critical processes into one streamlined unit.
Four-in-One Functionality: Seamlessly executes dreg interception, dreg removal, spiral lifting, and pressing dewatering simultaneously.
Footprint Reduction: By consolidating these steps, it drastically reduces civil engineering costs and saves valuable floor space.
Volume Reduction: The Shaft Screw Conveying Presser vigorously squeezes the lifted slag. The resulting dewatered dregs are significantly lighter and smaller in volume, which directly slashes transportation and landfill disposal costs.
Modern regulatory standards and community expectations demand that treatment facilities operate without negatively impacting the surrounding air quality. Open-air screening processes are no longer acceptable due to the release of volatile compounds and foul odors.
To address this, our equipment features a meticulously engineered fully sealing structure. Every access panel, joint, and discharge port is designed to lock in gases. This complete containment prevents the leakage of raw sewage odors into the working environment. Not only does this keep your facility compliant with strict environmental protection laws, but it also creates a significantly safer, more hygienic, and more pleasant working environment for your on-site personnel. The entire screening and pressing process remains entirely out of sight and smell.
Long-term operational expenditure (OPEX) is a decisive factor for any facility upgrade. While the machine performs heavy-duty extraction and pressing, its energy footprint is remarkably small, ensuring a rapid return on investment.
Ultra-Low Power Draw: Driven by a highly efficient 1.1kw motor, the system consumes a fraction of the electricity required by traditional multi-stage screening setups.
Acoustic Comfort: The precision engineering and slow rotational speed result in exceptionally low noise emissions, contributing to a safer auditory environment for workers.
Minimal Maintenance Costs: The combination of self-lubricating bearings, automated cleaning, and durable stainless steel means that replacement parts and maintenance labor are virtually eliminated from your annual budget.
No two water treatment sites are exactly alike. Whether dealing with the heavy organic loads of a food processing plant or the high-volume flow of a municipal grid, this system is designed for supreme adaptability.
Mounted at an optimal 35-degree angle, it is specifically tailored to fit into low-depth channels where traditional vertical screens would fail. It has proven its exceptional reliability across a vast array of sectors, including urban wastewater networks, complex industrial effluent streams, the rigorous food and beverage process industry, and the heavy-duty paper manufacturing sector.

The underwater bearing is crafted from a specialized copper alloy that utilizes the surrounding water as a natural lubricant. Because it does not require manual greasing or oiling, facility operators never have to halt operations, drain the channel, or send personnel into hazardous confined spaces for routine bearing maintenance. This significantly lowers labor costs and improves site safety.
Yes. We offer grid gaps ranging from 0.5mm to 5mm. For industries like paper manufacturing where fine pulp fibers are present, a smaller gap (e.g., 0.5mm or 1mm) is ideal. For municipal intakes dealing with larger debris, a 3mm to 5mm gap ensures high flow rates while still protecting downstream pumps. We assist in selecting the exact specification based on your unique solid waste profile.
The equipment is specifically engineered to operate at a slow, controlled rotational speed. If a hard object, such as a rock or a piece of heavy timber, enters the drum, the slow kinetic movement prevents high-impact collisions. The object is gently intercepted by the grid and eventually lifted out by the spiral mechanism without tearing the mesh or damaging the internal nylon brushes.
Raw screen slag is incredibly heavy because it retains a massive amount of water. The Shaft Screw Conveying Presser actively squeezes the slag as it is lifted out of the channel. By forcing the water to drain back into the system via gravity, the final discharged waste is highly compacted and relatively dry. This drastic reduction in volume and weight directly translates to fewer hauling trips and lower landfill tipping fees.
The fully sealing structure is highly effective at containing standard nuisance odors, hydrogen sulfide, and general wastewater aerosols, preventing them from escaping into the facility. While it provides an excellent barrier that drastically improves the working environment and aids in environmental compliance, facilities dealing with extreme concentrations of explosive VOCs should consult with our engineering team to ensure the integration of appropriate external ventilation and gas-scrubbing connections.
