Abstract
STUDIES INDICATE THAT STRAIGHT SEPTAGE INTRODUCTION TO ACT IVATED SLUDGE PLANTS CAUSES SHOCK LOADING AND SUBSEQUENT VIOLATION OF EFFLUENT PERMIT STANDARDS. THIS PROJECT INTENDS TO EVALUATE DEWATERING OF SLUDGE BY THEUSE OF WIRE CLOTH SCREENING TO DETERMINE IF THE DEWATERED SLUDGE MEETS LANDFILL ACCEPTABILITY STANDARDS. IT INTENDS A ALSO TO DETERMINE IF THE RETURN OF THE FILTRATE TO THE S SEPTIC TANK OF ORIGIN OR ANOTHER SEPTIC TANK IMPAIRS THE FUNCTION OF LEACHING FIELDS, OR IF POTENTIAL PATHOGEN TR TRANSFER FROM ONE TANK TO ANOTHER CREATES A PUBLIC HEALTH R RISK. THIS STUDY WILL PILOT TEST FILTRATION OF SEPTAGE WITHA SUBSEQUENT PHYSICAL AND CHEMICAL ANALYSIS OF THE SLUDGE AND FILTRATE. AN EVALUATION OF EXISTING DATA WILL OCCUR TO ASSESS THE IMPACT OF FILTRATE ON THE FUNCTION OF THE LEACHI ING FIELD IN ADDITION TO THE REDUCTION OF THE RESTING PERIOD. VARIOUS CHEMICALS AND POLYMERS WILL BE EVALUATED FOR E EFFECTIVENESS IN THE STRAINING OF SEPTAGE. THE TECHNOLOGIESIN QUESTION ARE (1) MOBILE VACUUM FILTER AND (2) MOBILE M MICRO SCREENS. THIS WILL ALSO INCLUDE AN ECONOMIC ANALYSIS. IT IS EXPECTED THAT THIS TECHNOLOGY WILL IMPROVED THE OUTF FLOW CHARACTERISTICS OF STP'S OF DESIGN FLOWS 5 MGD BY REM REMOVING THE SHOCK LOAD TO SEPTAGE FROM THE HEADWORKS. V VACUUM FILTRATION AT THE PLANTS SHOULD IMPROVE, AND FILT FILTRATE SHOULD CONTAIN LOWER BOD, TSS, AND VSS. IN ADDITION, IT IS EXPECTED THAT THIS TECHNOLOGY WILL HAVE NO ADVERSE IMPACT ON THE LEACHING CHARACTERISTICS OF RESIDENT IAL SEPTIC SYSTEMS, AND WILL ACTUALLY INCREASE THE PUMPING FREQUENCY DUE TO THE COST SAVINGS TO THE HOMEOWNER.
