Treatment of Sewage Sewage treatment is basically the process involved when wastewater from households is treated by removing any contaminants in it. Biological, chemical as well as physical processes are involved during wastewater treatment in order to remove any contaminants that are present in the sewage. Sludge is the term for the semi-solid waste that is sewage before it has been treated. In order for sludge to be ready for land application or disposal, it has to go through several treatment stages. Another term used to refer to sewage treatment is wastewater treatment. Sewage that is found in sewers is usually produced by industrial, institutional, residential as well as commercial establishments. The water used in most households in showers, sinks, kitchens, showers among others forms the sewage that flows in sewers. Sewage from the sewers is carried into the treatment plant using large pipes put in place. Water treatment is usually a process and it occurs in various stages. The first stage is known as screening where large contaminants such as face wipes, diapers, sanitary, bottles, rags and other wastes are removed. Removal of these contaminants is usually done in the first stage in order to prevent blockage or damage of equipment used in the treatment plant. The grit that is washed into the sewer is gotten rid of by using special equipment. The second stage of sewage treatment is where organic solid matter and wastewater are separated. There are huge settlement tanks where the sewage is passed through in order to get rid of human waste. In doing so, solid waste sinks to the bottom of the and is basically referred to as sludge. There are large scrappers found in the settlement tanks whose purpose is to scrape off the solid waste at the bottom of the tank and get them to another compartment for further treatment. There are aeration lanes in these treatment plants whereby wastewater is put once sludge has been scrapped off. The scrapping stage might cause small bits of sludge to get into the wastewater which are broken down further using bacteria present in the water.
Figuring Out Treatments
During the final treatment stage, the wastewater goes through a settlement tank. The small bits of sludge in the mixture settles at the bottom once the bacteria acts on the wastewater. Once the process is over, the water is devoid of any harmful substances such as chemicals or toxins. The wastewater is then allowed to pass through a wall where it is filtered using a bed of sand in order to get rid of any additional particles.
The Art of Mastering Treatments
The water that is released into the environment after the treatment process is usually devoid of any toxins or contaminants which is why this process is very useful. The water can be purified to be pumped into homes for people to use for domestic purposes without it getting wasted.
