a to z of sewage On daily basis, thousands of tons of sewage from domestic, industrial and commercial institutions are generated. This sewage could have physical, chemical and biological contaminants that can't be allowed to flow in to clean water. Sewage treatment plants ( click here ) treat this waste in such a way that the dangerous waste is separated from other fluids and waste and then send the remaining safe waste to water bodies like river and sea. Mechanism of sewage treatment plant We can roughly divide the process of sewage treatment in three segments. These processes help us understand the working of sewage treatment plant easily. - Clarification or sedimentation: The first process is of separating the solid sludge and waste that settles on the bottom and the liquids and oils that float on the top. This is done with the help of clarifiers or clariflocculators. This is a very important process, as it reduces biological oxygen demand (BOD) and the loading time, so that there is considerably less material left for treatment in the next process. - Aerobic treatment: The next process is known as aerobic treatment and they help by increasing the oxygen content in the tank, thus increasing the speed of sewage treatment. Aerobic treatment is done with the help of aerators and they are very crucial to sewage treatment as the waste matter have a high level of demand for oxygen. - Disinfection: The last process is known as disinfection. It involves physical or chemical disinfection of toxic waste so that it becomes safe to be discharge into the local water bodies. This is also a very important process for industrial and commercial institutions. Sewage treatment plants handling domestic waste focus more on the above two processes. Importance of sewage treatment Every process has its own set of benefits. Let's take sewage treatment for instance, this process helps in curbing the dangerous air emissions, stopping the mixing of toxic waste in local water bodies, managing the ever-increasing waste and above all limiting the water-borne and air-borne diseases that can arise from untreated sewage. Proper sewage treatment It is very necessary to manage the sewage treatment plant effectively and use only the highest quality equipment and machineries that meet the industrial standard. Low quality machinery will


hamper the process at every level – for instance the solid sludge and liquid waste won't be separated effectively, leading to deposition of sewage in tanks. Improper aeration will build up toxic waste in the long run and make the nearby surrounding areas too dangerous to live in. This can not only invite action from government organizations but also make it dangerous for everyone involved. Moreover, sub-standard products will consume more energy leading to high utilization of resources and electricity bills. Here are a few pointers that can help you avoid potential disasters later. * Take care heavy crusts are not formed in the base * Check for growth of biological matter * See if there is any growth of filaments in aeration tank All in all, sewage treatment plants ( visit here ) must not be taken lightly and care must be taken of the above-mentioned points to avoid contingencies.
