The residue that accumulates in sewage treatment plants is called sludge (or biosolids). Sewage sludge is the solid, semisolid, or slurry residual material that is produced as a by-product of wastewater treatment processes.
Which of the following will result in accelerated eutrophication when?
Causes of accelerated eutrophication: Runoff of fertilizers from the nearby field to the water body causes algal bloom which leads to eutrophication. Sewage and industrial effluents increase the temperature and BOD of the water body, thereby causing increased biological activity, leading to algal blooms.
Which of the following will result in cultural eutrophication when introduced into streams lakes?
Human-induced eutrophication of freshwaters, also called cultural eutrophication, is largely a result of increased phosphorus inputs from sources such as agricultural fertilizers or partially treated sewage.
