As environmental protection gains prominence globally, alongside a rising emphasis on water reuse and sustainable municipal infrastructure development, there's a burgeoning worldwide demand for efficient and cost-effective sewage treatment solutions. Recently, our company successfully delivered a comprehensive sewage sludge treatment system to an overseas client. This system comprises a Slant Plate Clarifier, a Screw Press Dewatering Machine, and an integrated Chemical Dosing Unit, showcasing the growing international acceptance of compact and energy-efficient sludge treatment technologies.

In numerous municipal and industrial wastewater treatment facilities, front-end sludge concentration is pivotal for enhancing overall treatment efficiency. The Slant Plate Clarifier, also referred to as an inclined plate clarifier, serves as a widely adopted pre-concentration unit to elevate sludge concentration prior to dewatering. Compared to traditional settling tanks, slant plate clarifiers occupy a significantly smaller area while offering a much larger effective settling surface. This characteristic renders them especially suitable for overseas projects constrained by limited land availability or high civil construction expenses.
The Slant Plate Clarifier is a liquid-solid separation apparatus designed to boost sedimentation efficiency. When the flocculated sewage stream enters the clarifier's inlet trough, it ascends between a series of inclined plates. Under the influence of gravity, solid particles settle onto the plate surfaces and slide down into the sludge collection hopper. Simultaneously, clarified effluent rises through orifice holes and exits from the unit's top. This design substantially shortens the settling distance and enhances separation performance, even under fluctuating flow conditions.
From a market standpoint, slant plate clarifiers are gaining increasing favor in municipal sewage treatment, industrial wastewater pretreatment, and sludge thickening applications. They are more economical than decanter centrifuges, consume less energy, and are simpler to operate and maintain. These benefits make slant plate clarifiers an appealing option for developing markets and projects aiming to cut operational costs without sacrificing treatment efficiency.

The Dewatering Screw Press, as the central sludge dewatering equipment in this system, plays a crucial role in reducing sludge volume and achieving consistent dry solids content. Operating continuously at a low rotational speed, the screw press ensures low power consumption, minimal noise, and reliable long-term performance. Its clog-free design is particularly well-suited for sewage sludge with high organic content and variable characteristics, which are common challenges in overseas wastewater treatment projects.

To guarantee effective flocculation and stable dewatering performance, the system incorporates a Chemical Dosing Unit for flocculant preparation and dosing. This unit enables precise polymer solution preparation and controlled dosing, optimizing sludge conditioning before both thickening and dewatering stages. This integrated approach enhances sludge cake dryness and reduces overall chemical usage.

This overseas project exemplifies how the integration of a Slant Plate Clarifier, Screw Press, and Chemical Dosing Unit can create a compact, efficient, and cost-effective sewage sludge treatment solution. With the global demand for sustainable wastewater treatment on the rise, such integrated systems are poised to assume an increasingly significant role in municipal and industrial sewage treatment plants worldwide.
