Abstract
Liq. from the bottom of dumping tanks for solid when refuse is treated by drawing off settled percolate. This is conc. pref. by mixing with a stream of hot air to evaporate some of the water and volatile organics. The conc. percolate sepd. from the vapour phase is returned to the percolate settling tank. The vapour phase is oxidised. Periodically residual sludge is extracted from the settling tank for toxic waste storage. In the percolate concentrator, percolate from the settling tank is sprayed upwardly from nozzles countercurrent to a stream of hot air introduced via inlet. A downwards spiralling movement is induced by blades. The mixt. of air, water and volatile organics is driven to the lower section of the concentrator from where it is withdrawn through an elbow extractor pipe. Non-evaporated liq. consisting of percolate with a high concn. of heavy pollutants is collected on sloping base from where it is returned to the settling tank.
