ABSTRACT:
Liquid/solids feed to be filtered is uniformly distributed over a filter surface by (i) initially, continuously introducing said liquid/solids feed into the feeder compartment of a compartmentalized, partitioned feed-distribution box, said feeder compartment having a volume such that no decantation results, (ii) continuing such feed as to effect an overflow of feed from said feeder compartment into a second, distribution compartment, over a partition or common wall member therebetween, via a plurality of outlet openings shaped into the top of said partition along the length thereof and being sufficiently few in number such that the rate of flow of the liquid/solids stream flowing through each opening is high, and (iii) thence uniformly cascading the entire flow of liquid/solids stream to be filtered onto suitable filter surface, advantageously after a change in the downward direction thereof.
