| Abstract |
A trench method was tested for transporting and placing digested and limed raw (undigested) sewage sludges (8% and 20% solids) in trenches in study soil at loadings up to 1150 dry tons/hectare (500 dry tons/acre) without odor problems or hazard of surface runoff. Field scale trenching was best achieved by digging the trenches on contour not more than 75 cm deep, 60 cm wide, and from 60 to 75 cm apart. The study indicated that the best sludge transport method would employ concrete mixer trucks. Trenches could then be filled directly from discharge chutes or indirectly with a peristaltic pump. A tracked trenching machine with a maneuverable rear-mounted digging wheel dug a new trench and simultaneously backfilled a parallel sludged trench. In 2 years, neither heavy metals nor pollution indicator organisms (coliform and salmonella) have moved more than about 30 cm from entrenched sludge into surrounding soil. Moderate amounts of nitrate nitrogen have moved into underdrainage water but not into the underground aquifier. The lime in the sludge reduced metal movement into soil and availability to crops and metal uptake was modest. Tested agricultural practices included cross ripping, tilling, and cropping, with grasses recommended for the first year. Entrenchment appeared feasible for sludge disposal and improving marginal land. |
