Following a brief review of the removal of pollution from wastewaters and the consequent production of primary and secondary sludges, this module examines the characteristics of industrial and municipal sewage sludges and the options available for subsequent treatment and reuse. Sludge removal and consolidation, conditioning, anaerobic (and aerobic) digestion, mechanical dewatering, thermal drying and incineration are explained and discussed together with advanced sludge treatment (AST) options, including pyrolysis and gasification. Combined heat and power and energy from waste issues are also dealt with together with a particular emphasis on land application of stabilised sludges for agriculture, horticulture and reclamation uses. The module also reviews the relevant UK legislative and regulatory framework relating to sewage sludge management/reuse.
By the end of this course you will:
Understand how sludge is produced and measured including key terminology Be able to identify the principle elements of sludge treatment including advanced treatment Have a clear view of the regulations surrounding sludge treatment and recycling Understand the proposed changes from Ofwat for introducing sludge markets.
