Each and every one across the world needs clean H2O for everyday life. This liquid is always vital for our hygiene, health and even productivity of our community. To obtain it for consumption and other uses, you need to do proper treatment. The treatment process vary across the globe depending on the technology used in the plant and which type of water needs to be processed. For that reason, in the following discussion,
This is the first stage and during water treatment process, liquid aluminum is added to the raw water. The liquid aluminum is very significant at this point since it makes dirty tiny elements in water to clot together or rather form a mass Thereafter, coagulated dirt forms flocs which can easily be removed by filtration.
After floc constituent parts passes through the treatment process by GIA, they move to the sedimentation tank where H2O moves slowly allowing flocks to settle down. The flocks that collect at the bottom of the basin are called sludge which is piped to the lagoon for drying.
In this stage, H2O moves through a filter so that the settled constituent parts can be removed. The filters which does the job are made of elements of gravel and sand and in other cases anthracite. Filtration is very important as it removes impurities and disinfects.
This stage involves the use of chlorine disinfectant. The disinfectant ensures that any disease causing virus, bacteria or parasite is totally eliminated. This stage is very important since it makes sure that no any attempts of biological contamination of water.
The solid constituent parts that are collected and have settled at the bottom of the tank are collected by filtration and sedimentation so that they can be dried by lagoons.
In the stage, lime is actually added to ensure that water PH is correct and importantly, it is used to stabilize the natural softness so that there is no corrosion in the distribution system.
