Benefits Of Sewage Treatment Process

By Joshua Perry


Water is life and its beyond any reasonable doubt that water is one of the most crucial component in our lives, without water life can not be easy. So any efforts to treat the sewage water and re-cycling it back for re-use is very important. This is where sewage treatment process comes in.

The first stage in sewage treatment is the screening, here floating and suspended objects or solid are removed. These objects may include broken bottles, sanitary items, plastics, rags, nappies and even towels. This process ensures that the incoming waste water BOD is reduced to 20-30% and 50-60% that of suspended solids.

However, the sewerage systems helps in keeping the environment clean since it helps us in managing our liquid wastes. The systems have also relieved the continuous cesspool emptying which was being carried out before the introduction of these systems thus improving the quality of life.

On the other hand, the treatment process helps in improving and promoting healthy living standards. If water from sewage systems is channeled to the rivers and left untreated it can pose massive health risks. This is because these waters act as breeding areas for mosquitoes which are known for transmitting diseases. To reduce the diseases outbreak, stringent measures including proper treatment of this waste should be taken in to consideration when disposing this water.

To achieve this microbes are used which gets involved in the consumption of the organic matter as food which is later converted into water, carbon dioxide and energy. Secondary sedimentation then follows, where further suspended solids are removed. Though not 100% removed, the procedure can remove about 85% of these BOD and suspended solids.

During the treatment process, the odor can be a nuisance to the environment. This is because its very difficult to control the bad smell emanating from the sewage. The situation worsens when certain chemicals are used to treat the waste. This leads to increased pollution of the environment.

Apart from reducing the acidity of water, the purification process is used to remove hardness in water by making it soft and safe or human use. During laundry when soft water is used less detergent and soap is used. This on the other hand reduces the cost compared to when hard water is used.

To remove water particles, water is left to run on a bed of sand to ensure further filtering. After the filtration process has been carried out, the water at this level is always safe to be freely channeled to the river. This water can be re-used in homesteads, for irrigation of plants and also in making the rivers healthy. The quality of water channeled to these rivers is normally controlled by the environment management authority agencies which ensure only clean treated water is piped to these water catchment areas. Water treatment procedure comes along with a lot of advantages in that it ensures that the water we use in irrigating our crops and also re-used in our homes is safe for all our domestic activities we carry out in our homes.
