Sewage collection and treatment

Sewage collection and treatment

(p.5) 2. Sewage collection and treatment
Environmental Pollution Studies
Liverpool University Press

This chapter discusses sewerage systems and methods of sewage treatment. There are two types of sewerage systems: ‘combined’ and ‘separate’. In combined sewerage systems, rainwater from roads and roofs and sewage from homes and wastewater from factories are collected in the same pipe system and then transported to a sewage treatment works (STW). In separate sewerage systems, the foul drainage water from homes and factories is collected in one sewer and piped to the STW for treatment. The methods of sewage treatment discussed in this chapter include the percolating filter system and activated sludge. The chapter also describes the chemistry of sewage effluent and then presents a case study on sewage treatment in East Kilbride, Scotland.
