ABSTRACT:
An integrated unitary comminuting system adapted for wastewater channel use is provided with devices which include a stationary single or dual semi-cylindrical-like sizing and sweeping screen member each having a rotating sweeping mechanism of interactive slotted comb bars or blades with tynes or teeth, so as to sweep and clear lodged or agglomerated solids adhering to the outer circumference surface of the semi-cylindrical-like screen member, disposed in spaced apart contiguous parallel relationship with a twin shaft shredder device having two parallel shafts with shredder or grinder teeth along the length thereof that rotate in opposite senses. The unitary system of devices may be positioned perpendicular between the influent and effluent side of the wastewater flow in a channel so that solids therein will encounter the semi-cylindrical-like sizing and sweeping screen members or the twin shaft shredder as the wastewater flows through the channel. Both the single or dual stationary semi-cylindrical-like screen devices cause solids which do not flow directly therethrough to be forcefully swept and diverted from the outer surfaces of the stationary sizing screen members by the rotating sweeping interactive blades mechanism of the system into surrounding the wastewater flow so as to cause and divert or direct the solids to flow into the twin shaft shredder device, aided by circulating wastewater currents generated in the wastewater flow near the entrance to the twin shaft shredder which is generated in part by the rotating sweeping interactive blades of the screening devices, whereupon the removed solids are efficiently channelled into the twin shaft shredder device along with the other wastewater and solids flow where they are reduced in particle size.
