It is used to remove the sludge from sewerage ponds (oxidation ponds) and sediment ponds. Sludge is pumped into the bag, and the water slowly seeps out, and the solids are collected in the bag. Sludge is typically injected into the bag at about 3% suspended solids and accumulates to approximately 15 – 25%. At this point, it can be removed from the site.
EnviroSieve Dewatering Tubes are made to order. We can make any circumference tube up to 36m and any length tube up to 50m long. For each job, we size the tubes to ensure we maximise the effectiveness of the tubes while maintaining an allowable factor of safety.
