Title: Apparatus and method for treatment of waste water sludge
Inventor: KEW ALAN S
IPC: C02F3/12
Filed: 1993-02-17
Granted: 2001-01-16
Abstract: A method and apparatus for treating liquid waste water sludge after its generation and separation from the waste liquid involves propelling a plurality of separate streams of sludge via, for instance, a rotor (37) and then forcibly impacting sludge particles and microbial cells contained in the propelled streams of sludge against a contact surface such as a stator (59), for recirculation of sludge along toroidal paths (62) and (64), to thereby fragment the particles into smaller sized particles and break apart the organic cells. As a result of such a fragmentation process, water located in the pores of the sludge particles is released, thereby enhancing a subsequent dewatering process performed on the sludge. The destruction of the cells permits a subsequent solids digestion process to work more efficiently, while also permitting a more complete conversion to dissolved sugars, proteins and carbon dioxide.
