Biodegradable organics (e.g. BOD) which can provide as “food” for microorganisms in the receiving body. Microorganisms combine this matter with oxygen from the water to give way the energy they need to thrive and multiply; Sorry to say, this oxygen is too needed by fish and other organisms in the river. Heavy organic pollution can guide to “dead zones” where no fish can be bring into being; sudden releases of heavy organic loads can guide to dramatic “fishkills”.
Wastewater treatment plant
Wastewater
treatment is directly related to the standards and/or expectations set for the
effluent value. Wastewater treatment processes are intended to achieve
improvements in the quality of the wastewater. The various treatment processes
may reduce Suspended solids (physical particles that can choke rivers or
channels as they settle under gravity)

Pathogenic
bacteria and other disease causing organisms are most related where the
receiving water is used for drinking, or where people would or else be in close
up contact with it; and
Nutrients, including nitrates and phosphates. These
nutrients can lead to elevated concentrations of unwanted algae, which can
themselves become serious loads of biodegradable organic load.
Treatment processes might also neutralize or remove industrial
wastes and toxic chemicals. This kind of treatment should perfectly take place
at the industrial plant itself, prior to discharge of their effluent in
municipal sewers or water courses.
