Title: Method for distributing a sludge to be filtered over the upper surface of the filter cloth of a rotating belt filter

Abstract: The present invention is concerned with a method of distributing sludge to be filtered, to the filter surface of an endless-belt filter, so as to maintain a uniform solids content of said sludge. The incoming sludge is in this connection charged to a sludge receiving means in which the sludge is divided into two part-flows such that one of said part-flows contains a higher percentage of solids than the other, whereafter the two part-flows are united and the resultant flow discharged to said filter surface.
