Water pollution - Wikipedia
Water pollution - Wikipedia

Water pollution is the contamination of water bodies, usually as a result of human activities.Water bodies include for example lakes, rivers, oceans, aquifers and groundwater.Water pollution results when contaminants are introduced into the natural environment. For example, releasing inadequately treated ,wastewater, into natural water bodies can lead to degradation of aquatic ecosystems.

Being strongly hydrophobic these organic ,pollutants, are efficiently removed during urban ,wastewater, treatment (WWTS) and bind to the sludge solids. However, the increasing body of scientific evidence has not identified a potential harmful impact of these substances on the environment in the context of the urban ,wastewater, system.

The aim of this research was to determine the effect of formic ,acid, on pollutant decompo-sition in textile ,wastewater, subjected to treatment by the Fenton method. To estimate the effect of formic ,acid, on treatment efficiency for different types of textile ,wastewater, tested, COD reduction in mixtures of ,wastewater, and formic ,acid, was calculated.
