2018-11-8 · Sewage sludge treatment describes the processes used to manage and dispose of sewage sludge produced during sewage treatment. Sludge is mostly water with lesser amounts of solid material removed from liquid sewage.
2009-9-9 · The question of sludge handling and treatment of P in side streams is also being addressed. EBPR the P content is even higher. Thus sand filtration or other method of TSS removal (e.g., merane, chemical precipitation) is likely necessary for plants with low effluent (<0.1 mg/L) effluent P levels at modest cost and with minimal
