Thelatter is form-ed by the in-clined surface, a, ha\-ing trans-verse ribs. 6, and slots orperforations, d, so arrangedthat the liquid flows over theupper edge of one transverse rib,and falls into the gutter formedby the rib below, being cooledby the air which is drawn inthrough the slots or perforations,d.

Pekforated hoods of inverted V-shape are fittedover the inlet pipes for the cleansing liquid to formseparating chambers, the washing liquid escapingthrough the lower and the air through the upperperforations, and thence passing upwards throughthe fUtering medium.
