High Solids Pre-Treatment Unit
As we are continuously being presented with the more difficult and challenging sludges that require treatment and recovery we’ve found it necessary to develop a pre-treatment process to enable us to deal with these complex obstacles.
The High Solids Pre-Treatment Unit (HSPU) has been specifically designed to handle a wide range of sludge and other materials particularly the difficult unpumpable sludges found in open pits or lagoons.
The aim is to keep the sludge in suspension, add heat to aid processing and remove any heavy debris prior to centrifugation. The HSPU can also be used to wash contaminated stone following a spill, allowing it to be re-used rather than disposed of. In conjunction with the centrifuge system this now enables us to maximise oil recovery from the waste sludge.
