Safe Disposal of Wastewater – A Crucial Step Towards Happy Environment Treatment and safe disposal of wastewater is done by packaged sewage treatment plant to contribute to the environment. Sewage treatment facilitate protection of environment and environmental conservation since the wastewater collected throughout the towns and cities must be returned to receiving land or to water body. Once the organic matter, pathogens, and other concentrations of solids are removed to attain the set standards, the treated water is then released into water or land to sustain the environment.
The job of the design engineer is to intend the process that ensures the technical feasibility of the treatment process, considering other factors like construction and maintenance costs, the availability of the equipment and construction materials, and experienced labor. Most of the sewage treatment plants use aerobic metabolism to remove the organic matter. The widely used aerobic processes are the activated sludge process, trickling filter, oxidation ditch, and aerated lagoons. Stabilization ponds apply both aerobic and anaerobic mechanisms.
