How Biological Treatment of Wastewater Cleans Our Water Naturally

Ever wondered what makes dirty water fit for the rivers or lakes again? biological treatment of wastewater is based on using millions of natural microorganisms that collaborate to degrade the organic waste. Based on the amount of oxygen, this takes place aerobically, anaerobically or anoxically, and each method deals with certain types of pollutants such as nitrogen and phosphorus. Methods including activated sludge basins, trickling filters and aerated lagoons make microorganisms do their work in an effective way. This is a biological process that is quite important for the purity of our waters.
