Sewage Water Treatment - Impurities in Sewage Wastewater
Sewage Water is polluted by a variety of organic matter.
Members of the animal and plant kingdom, and humans are the starting points of natural or synthetic organic compounds. Detergents, cosmetics, food, agricultural products, human excreta, and paper products, and wastes from commercial activities are all organic in origin and considerable in quantity.
Organic compounds yielded by the above sources are made up of trace elements such as hydrogen, carbon, nitrogen, oxygen, and sulfur. Organic compounds including carbohydrates, proteins and fats are degradable by organisms; still, they can contaminate the medium in which they occur.
Large concentration of degradable organics in wastewater is dangerous to springs, seas and lakes since organisms use up oxygen in solution in water, to break down the wastes. This can deplete the supply of oxygen in the water required by aquatic life forms, causing the death of large numbers of fish, causing the rotten smell of decomposed matter, and causing overall deterioration of water quality.
Certain organic compounds are less volatile than others and cannot be decomposed instantaneously by bacteria. This calls for additional effort in treatment of wastewater. This is true with many synthetic organic compounds targeted at the farm and manufacturing sectors.
It is sad but true that some of the manually synthesized organic compounds and that belong to fried oils, and fried meats are poisonous to fish, humans and water plants alike but are frequently discarded in polluting ways by mixing with rain water harvested in storm water drains.
Hence, the receiving water bodies of tainted wastewater, such as lakes, seas, and oceans, kill or contaminate fish, rendering them uneatable. Such pollutants can bring down the success rate of the chemical treatment processes.
Contamination of wastewater by organic substances thus invites more efforts in waste effluent treatment.
