Abstract

Liq. contg. suspended solids and e.g. active charcoal purified, is introduced evenly to the bottom of a tank, in pulsed flow, and passes upwards between parallel partitions inclined at 45-70 degrees to horizontal, which pref. have transverse deflector, plates, obscuring up to 2/3 of flow passages. Deflectors have separation 1-5 times that of partitions, and are inclined downwards at 20-70 degrees tp horizontal. Purified water passes from top of tank, via trough collectors.
