Municipal Sewage Sludge

Sludge and residue thickening, dewatering, drying, stabilization and resource-recovery engineering based on verified composition and final outlet criteria.

SLUDGE TREATMENT · SEPARATE ENGINEERING ROUTE

Municipal Sewage Sludge

Primary sludge, waste activated sludge and digested sludge from municipal sewage-treatment plants. It is kept separate from livestock/slaughterhouse sludge and from industrial or oily sludge.

Process Flow

Sludge Receipt / ThickeningPolymer ConditioningBelt Press / Screw Press / CentrifugeCake ConveyingOptional Low-temperature DryingApproved Stabilization, Co-processing or Disposal Route

Preliminary Capacity Range

Configurable range10–500 wet t/day or 2–100 m³/h dewatering feed
Final sizing basisRepresentative samples, minimum / normal / peak flow, operating hours, dry-solids load, required cake moisture, utilities and final output route.

Engineering Boundary

Required analyses include source process, dry solids, volatile solids, pathogens, grit, salinity, nutrients, metals, organic contaminants, calorific value after dewatering and dewaterability. The final route depends on local sewage-sludge regulations and verified acceptance criteria.
