Abstract

The effluent is drained through textile filter pockets in the form of suspended cylindrical sleeves. Pref. the sleeves hang down from the base of a tank raised aloft on a supporting structure. The tank is divided into compartments by partitions which can be underflowed so that effluent can pass from a compartment feeding sleeves which have become blocked to a compartment with clear sleeves. Each compartment pref. has a separately controlled inlet valve for effluent and compartments are interconnected through valved pipework. The tank discharges purified effluent via overflow and, even when the filter sleeves are blocked, accelerated sedimentation in the tank is sufficient to deposit most of the metal hydroxides est. Each sleeve is pref. cleared internally by an axially movable scraper cable-suspended from a reversing pulley. Device is used for purificn. of effluents from electroplating, metal pickling and other metal surface treating processes, partic. to prevent metal hydroxides etc. reaching waterways and drainage systems. The sepd. sludge is easily collected for disposal.
