De-watering sludge using optimal procedure for different dry-matter contents - where circular filter troughs rotate past sludge inlet and outlet, and sludge is subjected to filtration and vibration and is compressed by pressure plates

摘要

In a new device and procedure for de-watering sludge, the sludge is treated in accordance with its consistency or dry-matter content with the most effective de-watering process for this condition, whereas previous de-watering procedures have made use of only a single process. USE/ADVANTAGE - Esp. for de-watering sewage sludge. Mfg. costs are low, a high degree of de-watering is achieved, and standing and filling periods are kept to a minimum
