However, the bulk of waste does not biodegrade quickly or ever. By thinking a Premium551 Words3 Pages Ritik.

Normally, BOD5 is used to prove the strength of untreated and treated municipal and biodegradable industrial effluents. COD is used to prove the strength of effluent that is either non biodegradable or contains compounds that inhibit activities of micro-organisms. The pH analysis is a step of the sourness of a effluent sample.

Biodegradable waste includes any organic matter in waste which can be broken down into carbon dioxide, water, methane or simple organic molecules by micro-organisms and other living things by composting, aerobic digestion, anaerobic digestion or similar processes. In waste management, it also includes some inorganic materials which can be decomposed by bacteria.

Water pollution is a major cause of concern these days and our government is taking conscientious efforts to preserve our water bodies and save them from furthe.

Garbage, Recycling, and Waste Management There are already ways of getting rid of garbage so people won’t have to see it or smell it.

The toxins may cause blood clotting, seizures or serious medical issues that can kill animals. The toxic water may also kill off surrounding plant life on riverbanks and the bottom of a.

The removal of COD and BOD are important from an environmental point view since high levels can deplete the level of dissolved oxygen in receiving rivers causing an increased amount of non-biodegradable organic matter.23 Some advantages and disadvantages for the various chemical-physical treatment processes applied for cleaning wastewater is listed in table 3 (edited from babu et al).
