FULL-SCALE CO-COMPOSTING OF SEWAGE SLUDGE AND WASTE MATERIALS AT VARIOUS MIXING PROPORTIONS AND AERIATION CONDITIONS TO PRODUCE STABILIZED COMPOST
Original language description
Two different sewage sludges were commercially co-composted with wood chips and grass to determine their conversion potential and the extent that it is affected by various operational parameters. A blend of three different SS streams composted more efficiently in terms of temperature than a single SS stream when co-treated with a bulking agent. WCh facilitated materials to obtained a high temperature over the sanitation limit and concurrently to acquire a high decomposition rate for a long period. Further increasing the fraction of WCh in mixture had an insignificant effect on the decomposition rate of organics in SS. The presence of grass in a mixture had a negative influence on composting temperature that retained below the sanitization limits during the entire process. Aeration led to an increment in temperature but the increase remained at levels lower than 20 oC throughout the trials. Concentration of heavy metals in all mixtures was sufficiently reduced with composting regardless of the SS type, mixing ratio, the use of a secondary organic substrate and aeriation.
