Sewage processing reduces the concentration of potentially harmful bacteria such as E. coli and Salmonella in the original sewage as many of them die during the processing because the conditions are not appropriate for them.
2. It is also important to reduce the amount of organic compounds in the effluents released into rivers from sewage works.
3. “If this is not done, then microbes naturally present in the river use the organic compounds as a source of energy and reproduce in huge numbers.”
4. “Since they respire aerobically, they use up much of the oxygen dissolved in the water, leaving little for other organisms such as invertebrates or fish, many of which will die.”
5. Sewage must therefore be treated to reduce the amount of organic matter, and thus reduce the Biological Oxygen Demand or BOD, defined as the amount of oxygen required by the aerobic microbes to decompose the organic compounds in a sample of water.

go site 1. Do we need to worry the same for oceans?
2. Will the pathogenic microbes if multiply in huge number reduce the oxygen level of oceans?
3. Has this happened in recent past and has been the hidden cause of multitudes of deaths of marine animals in oceans?
4. In less level of oxygen do otherwise useful microbes release toxins that kills marine animals?
5. Is there evidence that in the past developing countries near the oceans dumped sewage or waste therein?
6. Death and decay can end anything. Does this mean that if we don’t remove dead material from the bottom of oceans we invite pathogenic microbial multiplication?
7. If E. coli and Salmonella multiply real quick in oceans then will it mean death of marine animals? Can fish resist the microbes that multiply on its own excretion (sewage)?
8. Is there need of reducing organic material from oceans?
9. Is sewage the future of oceans if left untreated and not helped but harmed?
10. How can we change the future of oceans by NOT dumping waste but by removing waste?
