Description
Biological and chemical processes play a key role in the treatment of domestic wastewater and are becoming increasingly important in tackling the problems caused by industrial wastes. The first edition of this popular text focused on microbial systems and wastewater processes that are implemented in a treatment plant. While maintaining this approac
