ABSTRACT:
Apparatus for draining of muddy liquids, especially of sludges and slurries in sewage clarification plants, where first of all an ionic coagulant, eg., an anionic or cationic coagulating agent, is added to the muddy liquid in a first ionic coagulating means to obtain an aqueous sludge which is separated from the muddy liquid in a first coagulating chamber by sedimentation in a straining zone and wherein the aqueous sludge is subsequently filtered and pressed, whereafter the liquid is treated in a second coagulating or mixing chamber.
The apparatus to carry out the process comprises in addition to the first coagulation chamber coagulation chamber for the muddy liquid, a revolving screening belt constituting the filtering means for the straining zone and a series connected revolving screen belt press which aids in dewatering the filtered solids. This second coagulation chamber apparatus is located at the delivery end of the screening belt and constitutes the straining zone for the addition of the ionic coagulant of opposite charge to the aqueous slurry and includes the mixing chamber which has a slit outlet lying transversely above the receiving screen belt of the screen belt press whereby the dried filter cake leaves the screen belt press to provide as complete as possible transfer of the slurry cake from the revolving screen belt and belt press.
