Wastewater is polluted by various organic substances.

Vegetable Plants, animals and human beings comprise the origins of natural or synthetic organic compounds. Food, agricultural products, human excreta, paper products, detergents, and cosmetics, and wastes from households are all ample in volume and organic in nature.

Organic compounds built up from the above sources are made up of carbon, hydrogen, oxygen, nitrogen, sulfur and other trace elements. Organic compounds including fats, proteins and carbohydrates are degradable by organisms; still, they can contaminate the medium in which they occur.

Large concentration of degradable organics in wastewater is lethal to streams, lakes, and oceans because organisms consume oxygen dissolved in water, to degrade the wastes. This can deplete the dissolved oxygen in the body of water necessary for survival of water based life forms, causing the death of large numbers of fish, adding to the putrid smell, and leading to blanket lowering of water quality.

Some organic compounds are less volatile than others and cannot be decomposed instantaneously by bacteria. This requires some extra input while treating. This holds true with varied lab formulated organic compounds targeted at the farm and manufacturing sectors.

It is sad but true that some of the synthetic organic compounds and that belong to dyes, and pigments are toxic to humans, fish, and aquatic plants but often are poured off unheedingly in the environment in drains or carried in storm-water.

Thus, the large water bodies into which tainted wastewater flows, such as lakes, seas, and oceans, pollute fish, making them unfit to eat. Similar dissolved organics can further decrease the efficacy of the processes in treatment.

Pollution of wastewater by organic substances thereby marks the next area for innovation in waste effluent treatment.
