sand washing silo sludge process

Handbook of Water and Wastewater Treatment Technologies

Sludge or solid waste is unavoidably produced in the treatment of water containing suspended solids. One can select different technologies that will concentrate the solids, and thereby reduce the volumes that must be disposed of ultimately. This chapter focuses on sludge processing and post-processing technologies.

Handling and Storage

from storage silos to work areas. Transfer piping between the silo and the processing machines should optimally run no more than 200 feet to 300 feet. Keeping to that mea-sure may mean much longer lengths of transfer piping on the front end from the unload-ing area to the storage silo. One mistake often made in the design of a

Wastewater treatment

This recirculation is a key feature of the activated sludge process. The recycled microbes are well acclimated to the sewage environment and readily metabolize the organic materials in the primary effluent. The remaining 70 percent of the secondary sludge must be treated and disposed of in an acceptable manner (see Sludge treatment and disposal).

Importance of removing grit from wastewater
