The waste-sludge generated by primary and secondary (biological) treatment of municipal & industrial wastewater needs to be managed at every plant big or small. In the larger sewage treatment facilities waste sludge thickening and dewatering has always been assumed a necessity without the planners and designers thinking twice about the cost requirements.
In the smaller and decentralized STP’s where available investment is always lower, the on-site waste-sludge management (thickening & dewatering) maybe compromis...
The dewatering phases in municipal processes are basically of biological sludge originated from purification processes. Bilfinger Water Technologies has realized many complete installations of sludge purification regarding the processes of water purification, purification of waste waters and SUW (solid urban waste) treatment.
VITONE ECO decanters, together with all auxiliary machinery such as polypreparers, removal dewatered sludge screws, pumps, etcetera, are meant for the following uses: dehydration and thickening of sewage from civil and industrial purification plants; dehydration of vegetable biomasses and zootechnical sludge; waste water treatment for distilleries and fellmongering waste.
