Summary: | Large quantities of sewage sludge are available in Pakistan annually. Nutrient value of the sludge for soil fertilization is recognized. However, technology for conversion of the sludge into bio-solids acceptable for land applications does not exist. This provided bases for development and testing of a sludge treatment cum pelletization machine in the present study. The machine got capacity to sieve, grind, elevate, mix additives and palletize the sludge apart from drying the product to satisfy pathogen as well as vector attraction reduction requirements. The pilot-scale machine developed and tested in the present project can fill more than 160 bags of 20 kg each in a day of 8 hours. Each bag costs nearly rupees thirteen. |
