Abstract

A sludge distribution plant which receives a plurality of trucks either simultaneously or singly which bring in dried sludge in granular form and effluent both of which are separated between origin pickup and the distribution plant as shown in U.S. Pat. 4,046,689. At the plant site there are means for discharging the dry granular material containing debris into a sieve type shaker arranged over a conveyor belt both of which are on an angle of delination from the truck toward a central collector and conveyor system positioned to receive the non-liquid discharge contents of a plurality of trucks and which will separate the dry granular material from the debris and discharge each separately. There is means at each truck discharge area for discharging the concentrated effluent from each vehicle and storing same in underground tanks for further processing into urea fertilizer, bin storage means is positioned to receive the dried granular material and bin storing it until it is further processed for conversion into fertilizer, and bagging and storing means for the granular material is in communication with the bin storage means. Conveyor means are positioned to convey said granular material in said bin storage means to said bagging and storage means.

  1. 1.1. For use with a truck which converts sludge and effluent into a dry granular material forming a base for fertilizer and concentrated effluent in liquid form for making urea fertilizer, a sludge handling and distribution plant comprising:(a) means for receiving a plurality of truck bodies at a plurality of discharge areas;(b) means for discharging the dry granular material containing debris into a sieve type shaker arranged over a conveyor belt both of which are on an angle of declination from the truck toward a central collector and conveyor system positioned to receive the non-liquid discharge contents of a plurality of trucks and which will separate the dry granular material from the debris and discharge each separately,(c) means at each truck discharge area for discharging the concentrated liquid effluent from each vehicle and storing same in underground tanks for further processing into urea fertilizer;(d) bin storage means positioned to receive the dried granular material from said central collector and conveyor system and bin storing it until it is further processed for conversion into fertilizer, and(e) bagging and storing means for said granular material, in communication with said bin storage means,(f) and conveyor means positioned to convey said granular material from said bin storage means to said bagging and storage means.
