System for removing particulate matter from wastewater

Abstract

A system for, and method of, removing particulate material from wastewater discharged from an industrial source.

1 . A system for removing particulate material from wastewater discharged from an industrial process, said system comprising:
 a) a wastewater effluent feed path containing an introduced wastewater effluent from a source of wastewater;   b) at least one screening station disposed along said wastewater effluent feed path for filtering large sized particulate material from said wastewater effluent;   c) at least one first sedimentation station disposed along said wastewater effluent feed path for allowing particulate material suspended in said wastewater to settle out of the wastewater effluent;   d) removing a quantity of the wastewater effluent from said wastewater effluent feed path after said first sedimentation station, said quantity of water for reuse in said industrial process; and   e) at least one second sedimentation station disposed along said wastewater effluent feed path for allowing particulate material suspended in said wastewater to settle out of said wastewater effluent.   
     
     
         2 . The system of  claim 1 , further comprising a coagulation station disposed along said wastewater effluent feed path after said second sedimentation station for addition of a coagulant to said wastewater effluent to cause suspended particulate material to form a floc. 
     
     
         3 . The system of  claim 1 , further comprising a skimming station disposed along said wastewater effluent feed path after said coagulation station for skimming said floc from the surface of said wastewater effluent. 
     
     
         4 . The system of  claim 3 , wherein wastewater effluent passing out of the skimming station is discharged from said wastewater effluent feed path.
