Sludgecleaner STRAINPRESS®

Manufacturer: Huber Technologies

Coarse material separator for municipal and industrial sludge and process water
 Screening, dewatering and discharge in one working process
 Continuous coarse material separation under pressure
The STRAINPRESS® is a horizontal pipe-shaped coarse material separator which consists of inlet and driving zone, screening and press zone and finally a discharge section with a conical pressure regulating device. The coarse material is separated continuously under pressure and periodical cleaning of the screening zone by backwashing is not required.

 The STRAINPRESS® system can be integrated in a closed pipeline system.
 Screening, dewatering and transport of the coarse material in one operation.
 No second pump is required for the screened sludge owing to the closed and compact in-line system.
 Continuous coarse material separation under pressure with a loss of pressure between 0.4 and 0.6 bar
 Washing off sludge or backwashing is not necessary.
 The horizontally moveable screw can be re-adjusted to ensure continuously perfect screen cleaning.
 Fully-automatic continuous or intermittent operation.
 Little space required, easy subsequent installation into the pipeline.
 Insensitive to varying feed volumes or coarse material structures
 The automatic pressure requlating conus ensures uniform dewatering even with strongly varying coarse material quality and concentration.
 When handling sludges with heavily varying DS and coarse material content, the pressing screw starts to work in dependence of the operating pressure (filter cake resistance).

Key features:
 Coarse material screening and dewatering to approx. 45 % DS content
 Closed pipework system
 Pressure-fed system (in-line) for any type of sludge including viscous and grease containing sludge
 Reduces plant operation and maintenance costs and increases the operating reliability of downstream sludge treatment systems, such as thickening, digestion, dewatering, hygienisation, drying, etc.
 Perforations of 0.4 to 10 mm for solids/liquid separation also in industrial applications
 Throughput capacity of up to 110 m³/h for sludge, up to 200 m³/h for process water
 Reliable perforated plate cleaning without the need for any external water and without brushes, no back flushing required
 Automatic pressure cone system for maximum dewatering efficiency
 More than 1,000 installations worldwide
