Wuxi Ouyi Unveils Guide for Optimizing Sludge Dewatering

Wuxi Ouyi Environmental Protection Co., Ltd, a global supplier of wastewater treatment equipment, has unveiled a comprehensive guide on optimizing sludge dewatering in municipal sewage treatment. The company, known for its precision-engineered multi-disc screw press sludge dewatering machine, offers a detailed selection guide to help municipalities and wastewater treatment facilities improve their operational standards.

The guide highlights the importance of evaluating various technical dimensions when selecting an optimal dewatering setup. These include filtration mechanics, energy metrics, chemical dosing, footprint requirements, and wear resistance. Ouyi’s dewatering packages are designed to meet demanding municipal operational standards through five primary technical dimensions:

1. High-Throughput OIDL Series Capacity: The company’s multi-disc screw press lineup can handle dry solids from 10 kg/h to 640 kg/h across 18 specialized industrial models. This wide range ensures that facilities can choose a model that best suits their specific needs.

2. Precision Ring Fabrication and Tight Tolerances: Stainless steel ring flatness is maintained within ±0.02 mm to prevent clogging and eliminate biological floc bypass. This precision ensures consistent filtrate drainage while retaining fine biological floc particles.

3. Three-Chamber Automated Chemical Preparation: Continuous dry powder feeding and controlled hydration maintain solution concentration accuracy within ±2%, saving 10% to 20% on polymer costs. The system features separate dissolving, aging, and storage compartments with gravity overflow.

4. Compact Footprint and Civil Engineering Adaptability: Skid-mounted integration of electrical controls, flocculation tanks, and dewatering bodies occupies 1/3 to 1/5 of the area required by conventional filter press buildings. This compact design allows for efficient space utilization in existing facilities.

5. High-Velocity Thermal Wear Coatings: High-velocity oxygen-fuel tungsten carbide coating achieves HV 1300 microhardness, providing four times the abrasion resistance of untreated steel. Dynamic balancing calibration minimizes rotational vibration, protecting drive motors and reduction gearboxes during continuous duty.

The guide also emphasizes the importance of integrated factory direct sourcing over fragmented multi-vendor procurement. Sourcing a complete dewatering system from a single manufacturer offers distinct operational advantages, including unified engineering standards, streamlined installation support, and reduced costs. Municipal operators can save 10% to 20% on flocculant chemicals, reduce electrical power by 80% compared with centrifuges, and minimize daily wash water demand.
