ABSTRACT:
Improved clarity in treated wastewater is achieved by adding a flocculating agent following screening by fine mesh screening means, preferably a centrifugal screen separator. The effectiveness of the separator is improved, in turn, by preceding it in the direction of liquid flow by a corrugated plate interceptor to remove greases and oils. Preferably, fine mesh screening is carried out by two separate screening devices, one being a high liquid volume centrifugal screen strainer, and the other being a mechanically self-cleaned low liquid volume device. Wastewater is delivered to a thickener, preferably a corrugated plate separator, the thickened product being delivered to the low liquid volume device, and the supernatant being delivered to the centrifugal screen strainer. The corrugated plate interceptor not only acts as a thickener, but also eliminates grease and oil, which would interfere with the operation of the centrifugal screen strainer.
Organic sludge produced in the system is recycled through a carbonization system comprising a loop dryer and a molten salt column to produce a high grade activated carbon adsorbent.
The throughput of an electrolytic flotation apparatus is enhanced by the incorporation of a corrugated plate interceptor in its outlet, in which reverse flow of particulate matter takes place.
