Solids' Handling

Highly versatile devices that can provide conveyance, dewatering and compaction of solids retained from wastewater, stormwater or potable water flow stream applications.

John Meunier ROTOPAC® Type RPW Screw Washer Compactor

The single stage design is based on the use of a slow rotating spiral inserted into a perforated tube suitable for filtrate drainage. The screw receives solids from the screen, conveys them from one end to the other to provide dewatering, washing and compaction to finally expel them in a non dripping dry state. The quality of the finished product depends strongly on the initial product.

The addition of wash water increases the rate of return of washable organics with the filtrate to the main flow stream through a common drainage point. This pre-assembled unit eliminates problems associated with foul odour and unsanitary handling.

John Meunier ROTOPAC® Type RDW Shaftless Screw Compactor

The single stage design is based on the use of a slow rotating shaftless spiral inserted into a trough provided with perforated area suitable for filtrate drainage. The screw receives solids from the screen, conveys them from one end to the other to provide dewatering and compaction to finally expel them in a non dripping dry state. The quality of the finished product depends strongly on the initial product. The addition of wash water increases the rate of return of washable organics with the filtrate to the main flow stream through the common drainage point. This pre-assembled unit eliminates problems associated with foul odour and unsanitary handling.

John Meunier ROTOPAC® Type RCW Batch Washer Compactor

The dual stage design is based on the use of a slow rotating spiral inserted into a perforated tube suitable for filtrate drainage. The screw receives solids from the screen, conveys them from one end to the other to provide dewatering, washing and compaction to finally expel them in a non dripping dry state. The quality of the finished product depends strongly on the initial product. The forward-reverse motion of the screw plus the addition of water into the feed hopper increases the rate of return of washable organics with the filtrate to the main flow stream. This pre-assembled unit eliminates problems associated with foul odour and unsanitary handling.
