Method for treating water containing suspended solids from a sanitarysystem
Abstract
Abstract THE INVENTION PROVIDES AN IMPROVED METHOD AND APPARATUS FOR TREATING WATER CONTAINING SUSPENDED SOLIDS FROM A SANITARY SYSTEM. IN CARRYING OUT THE METHOD, THE WATER IS AERATED AND DELIVERED TO A SCREEN WITH A DIRECTIONAL COMPONENT ACROSS THE SCREEN SURFACE AND A DIRECTIONAL COMPONENT THROUGH THE SCREEN. THE SCREEN HAS OPENINGS LARGE ENOUGH TO PASS THE MAJORITY OF THE SOLIDS SUSPENDED IN THE WATER, AND HAS THE ABILITY TO HOLD A COATING OF THESE SOLIDS ON ITS UPSTREAM SIDE. THE FLOW OF WATER IS CONTROLLED SO THAT A COATING OF THE SUSPENDED SOLIDS FROM THE WATER IS FORMED ON THE SCREEN SURFACE. THE DELIVERY OF WATER CONTAINING THESE SUSPENDED SOLIDS TO THE SCREEN IS CONTINUED WITH A DIRECTIONAL COMPONENT ACROSS THE SCREEN AND A DIRECTIONAL COMPONENT THROUGH THE SCREEN, WHEREBY TO FILTER SOLIDS FROM THE WATER PASSING THROUGH THE COATING AND SCREEN. THE RELATIONSHIP BETWEEN THE DIRECTIONAL COMPONENTS ACROSS AND THROUGH THE SCREEN IS CONTROLLED TO MAINTAIN THE COATING ON THE SCREEN. THE WATER THAT IS PASSED THROUGH THE SCREEN IS STORED, AND IS RECYCLED TO THE SANITARY SYSTEM.
