BOEEP Sludge Dewatering Solution

BOEEP provides a system that concentrates sewage sludge before final treatment or reuse. The unit first doses the incoming sludge with polymers to bind fine particles. It then presses the mix to drive out free water. The result is a compact cake with high solids content. By cutting water weight, the solution lowers transport and disposal costs. The design fits into municipal and industrial treatment lines and works with standard controls. Operators gain steady output and easier handling of the remaining solids, setting the stage for efficient downstream processing.

Key Features of BOEEP Sludge Dewatering Systems

Energy Efficiency

Screw and belt units lower power use with slow rotation and gravity drainage.

Automation

Linked pumps and PLC keep flow, tension, and wash cycles on track without staff.

Versatility

Equipment processes oily or dilute sludge, handles raw surplus, and mounts on mobile skids.

Low Maintenance

Cloth‑free screws and quick‑swap belts cut service time and extend part life.

Environmental Protection

Closed frames suppress odor and noise, while filtrate returns to headworks to reduce discharge.

Operating Principles of BOEEP Sludge Dewatering Systems

BOEEP offers three sludge dewatering routes. Each route targets a different solids range and plant layout.

Screw Compression

Screw press uses a tapered shaft and rings to squeeze liquid from sludge. Feed enters a thickening zone, then moves to a narrowing pitch zone. A fixed back‑pressure plate sets cake dryness. Typical cake moisture is 75‑85%. Slow rotation lowers wear and power demand.

Gravity + Roll Press

Gravity and roller belt press. Sludge spreads on a permeable belt. Water drains by gravity first. The semi‑solid layer then passes through a set of rollers with rising pressure. The belt holds solids as water leaves. Final cake moisture reaches 70‑85%. The enclosure keeps odor in.

Integrated Pre‑thickening + Pressing

Integrated pre‑thickening and dewatering. A screw unit thickens dilute sludge in its inlet section. The same shaft then presses the mix to form cake. No separate tank is needed. Mobile skids add polymer, feed the screw, and drop cake straight to a truck.

Application Scenarios for BOEEP Sludge Dewatering

These systems serve municipal plants, industrial sites, mobile emergency work, and niche sludge tasks, cutting water weight and easing disposal.

Municipal Wastewater

A South African chemical plant uses a screw press to treat oily municipal sludge. An Australian pharmaceutical site runs a pre‑thickening screw for low‑strength sludge. Both setups cut water weight and reduce haul trips.
Industrial Wastewater

Paper and textile mills run DNY belt presses to squeeze high‑solids effluent. Slaughterhouses and food processors deploy mobile skids at scattered stations, keeping each site self‑contained.
Emergency Treatment

Mobile units roll out after floods. On‑board polymer dosing and screw pressing drain sludge on site. Filtrate returns to the works; cake loads straight into trucks.
