Labor Saving Volute Screw Press Separator
Description
The BOEEP volute screw press separator is a fully integrated sludge dewatering system that combines a screw body, driving device, filtrate receiver, mixing system, and heavy-duty flexible frame into a single compact unit. Unlike traditional dewatering methods that rely on easily clogged filter cloths or energy-intensive centrifuges, our innovative design completes both sludge concentration and dewatering in a single chamber.
This breakthrough technology efficiently handles both low- and high-density sludges, making it the preferred solution for municipal wastewater treatment plants and 8+ industrial sectors. By eliminating consumable parts and reducing manual intervention, the BOEEP volute screw press delivers a lower total cost of ownership (TCO) and faster return on investment (ROI) compared to competing systems.
How It Works & Core Technology
Advanced Dewatering Mechanism
The BOEEP volute screw press operates on a simple yet highly effective principle that combines mechanical pressure with continuous self-cleaning action. The process occurs in two sequential stages within the same chamber:
Sludge Concentration As sludge enters the chamber, the rotating screw shaft moves it forward, separating free water through the gaps between the fixed and movable rings.
High-Pressure Dewatering The variable-pitch screw shaft gradually increases pressure as sludge moves toward the discharge end, squeezing out bound water and producing a dry, compact sludge cake.
Core Components & Technical Innovation
Central Screw Shaft Precision-engineered with a variable pitch design to create progressive pressure along the length of the chamber. This ensures maximum water extraction while preventing sludge compaction and buildup.
Interlocking Fixed & Movable Ring Assembly (Patented Design) The heart of our anti-clogging technology. As the screw rotates, the movable rings continuously move relative to the fixed rings, creating a self-cleaning action that prevents sludge from adhering to the equipment surfaces. This eliminates the need for filter cloths entirely and solves the most common cause of downtime in traditional dewatering systems.
BOEEP vs. Traditional Dewatering Technologies
Technology Type | Core Pain Points | BOEEP Volute Screw Press Advantage |
|---|---|---|
Filter Press | Frequent filter cloth replacement, manual cleaning, long downtime | No filter cloths, self-cleaning, 24/7 continuous operation |
Centrifuge | High energy consumption, loud noise, complex maintenance | 70% lower energy use, low noise, minimal maintenance |
Belt Press | Severe clogging, sludge leakage, constant supervision | Zero clogging, closed system, fully automatic operation |
Key Features & Proven Customer Benefits
Wide Industry Compatibility
Handles sludge from municipal wastewater and 8+ industrial sectors (food & beverage, petrochemical, pharmaceutical). One system meets all your dewatering needs, eliminating redundant equipment investment.
Revolutionary Anti-Clogging Design
Self-cleaning ring assembly prevents clogging even for difficult oily and fibrous sludges. Eliminates costly unplanned downtime for manual cleaning and filter cloth replacement.
24/7 Continuous Automatic Operation
Fully automated PLC control system requires minimal human supervision. The system can run continuously without interruption, increasing processing capacity by up to 40% compared to batch systems.
Significant Operation Cost Savings
Low energy consumption, no consumable costs (filter cloths), and minimal maintenance. Delivers up to 35% lower total cost of ownership (TCO) over the 15+ year equipment lifespan.
Reduced Engineering Investment
All-in-one compact design eliminates the need for separate concentration and dewatering units. Saves 50%+ floor space and reduces installation time and costs by up to 60%.
Enhanced Phosphorus Removal
Optimized dewatering process improves phosphorus retention in sludge cake by up to 25%, helping wastewater treatment plants meet stringent nutrient discharge standards and avoid regulatory fines.
Industry Applications
Municipal Wastewater Treatment
Designed to handle variable sludge loads and compositions from municipal wastewater treatment plants. Our systems efficiently dewater primary and secondary sludge, producing a dry cake suitable for landfilling, incineration, or agricultural reuse.
Petrochemical & Oily Sludge Treatment
Oily sludge is notoriously difficult to dewater, as it quickly clogs traditional filter cloths and causes frequent downtime. The BOEEP volute screw press is specifically engineered for this challenge: its self-cleaning ring design prevents oil and sludge buildup, delivering consistent performance even for high-viscosity oily sludge. This makes it the premier solution for refineries, oilfields, and petrochemical plants.
Food & Beverage Processing
Handles high-organic-content sludge from food processing, beverage production, and brewing. Our systems are made from food-grade stainless steel and can be sanitized to meet strict food safety standards.
Slaughtering & Breeding
Efficiently dewaters high-fat and high-fiber sludge from slaughterhouses, livestock farms, and poultry processing plants. The anti-clogging design prevents buildup of hair, feathers, and other solid debris.

FAQ
How does a volute screw press separator work?
A volute screw press separator uses a rotating variable-pitch screw shaft to move sludge through a chamber surrounded by interlocking fixed and movable rings. As the screw rotates, it creates progressive pressure that squeezes water out of the sludge. The movable rings continuously move relative to the fixed rings, creating a self-cleaning action that prevents clogging.
What types of sludge can the BOEEP volute screw press handle?
The BOEEP volute screw press can handle a wide range of sludges, including municipal wastewater sludge, industrial oily sludge, food processing sludge, pharmaceutical sludge, papermaking sludge, and more. It is particularly effective for difficult-to-treat sludges that cause clogging in traditional systems.
What are the main advantages of a volute screw press over a filter press?
Unlike filter presses, volute screw presses have no filter cloths to replace, require minimal maintenance, and can operate continuously 24/7. They also have a smaller footprint, lower energy consumption, and produce less secondary pollution.
How much maintenance does a volute screw press require?
The BOEEP volute screw press requires very little maintenance. Routine maintenance includes regular lubrication of bearings and inspection of the screw and ring assembly. There are no consumable parts like filter cloths, which significantly reduces maintenance costs and downtime.
