Siltbuster

Siltbuster specialises in treating construction site wastewaters and has worked on some of the world's biggest construction projects. Through tests Siltbuster's experts recognised that the effluent would not quickly settle in a settlement tank. So Siltbuster devised a special filter press system with a cycle time fast enough to cope with dewatering the large volumes of slurry. The press connects to a Siltbuster PMPU20 unit which provides a two-stage continuous pH treatment for the residual water. This includes an initial pH adjustment, a clarification stage for the recovery of settled solids, followed by a final pH correction using carbon dioxide. During the treatment process the dry solids are recovered for off-site disposal. The remaining water's alkalinity is reduced from 12, which is the equivalent of bleach or oven cleaner, to a neutral 7 - making it compliant with Thames Water and safe to discharge to the sewer.
