The filter section comprises a filter tray having V or U shaped cross-sections and a loosely fitted recovable filter mat of a chemically resistant material, preferably a polyester coating glass fibre material or polypropylene, with optimum surface. The collected sludge is discharged at intervals through the bottom of the tank unit, the unit cleaning liquid is recirculated continuously after filtration and added with fresh cleaning liquid. The apparatus is equipped with a double-acting suction system for vapours from the cleaning liquid and involves substantial advantages to the working environment.
