Engineering & Process Design

Application-specific engineering for optimal dewatering results

Engineering Approach

Proper engineering is the foundation of successful sludge dewatering. Our approach combines process knowledge with application-specific data to deliver systems that perform reliably under real operating conditions. Every project begins with a thorough assessment of sludge characteristics, throughput requirements, operational constraints, and site conditions — before any equipment is selected.

Design & Engineering Topics

Screw Press Design

Screw press design fundamentals: screw geometry, screen configuration, zones, and how design parameters drive dewatering performance.

Design Criteria

Key design criteria for screw press selection: dry solids load, feed concentration, cake target, polymer, and material of construction.

Sludge Dewatering Design

Designing a complete sludge dewatering system: from sludge source and conditioning to dewatering, filtrate return, and cake handling.

Process Design

Process design for screw press dewatering: mass balance, operating strategy, control philosophy, and integration with the treatment plant.

Process Flow

The screw press dewatering process flow: sludge feed, polymer dosing, flocculation, dewatering, filtrate return, and cake discharge.

Hydraulic Design

Hydraulic design for screw press systems: feed pump selection, pipe sizing, filtrate drainage, and gravity return lines.

Solids Loading

Solids loading is the mass of dry solids processed per hour — the primary basis for screw press capacity engineering.

Dry Solids Loading

Engineering the dry solids load: measurement, design margins, and how DS loading maps to RF series capacity.

Polymer Conditioning

Polymer conditioning engineering: selecting flocculant type, charge, dose, make-up concentration, and dosing point for optimal flocs.

Flocculation Design

Flocculation design for screw press systems: reaction tank volume, mixing energy, residence time, and floc protection.

Filtrate Handling

Filtrate handling engineering: drainage, return routing, TSS quality, and impact on the wastewater treatment plant.

Cake Handling

Cake handling engineering: conveying, storage, and disposal routes for dewatered sludge cake — screw conveyors, skips, and silos.
