ABSTRACT:
The invention provides a multi-stage apparatus for continuous waste water filtration, comprising a first tank provided with a waste water inlet pipe to supply waste water containing suspended solids to the tank, means for adding a coagulant to the waste water and an outlet pipe, a second tank receiving the mixture of waste water and coagulant from the outlet pipe, the second tank being sufficiently large to allow larger suspended solids to settle and being provided with a lower, openable port for discharge of the settled solids and having an upper weir for discharge of partially-cleared water, a continuously-driven, non-taut perforated belt, having a surface positioned to receive, at a first location, a stream of the discharged, partially-cleared water, the belt perforations being sized to enable the passage of clear water therethrough while retaining fine and coagulated solids on the surface for subsequent discharge at a second location, and the belt being non-taut to form a trough for retaining a body of water above the surface thereof, a load sensor in contact with the belt to determine the combined weight of the belt and the water retained thereon and to control a motor of the belt and the speed thereof as a function of the weight, whereby a microcake of less than 1 mm thickness of fine and coagulated solids is formed and retained on the surface of the belt thereby improving the filtering capacity of the belt, a water collection body being provided under the first location for water passing through the belt perforations, and a solids collection bin being provided at the second location, for collection of particles falling off the belt at the second location.
