Every day, we use clean water, from bathing, washing, cooking, and so on. But do you know how the journey that has to be passed by clean air from what is in the air, river, mountain or mountain to our house? What about the people who process the water? Let’s learn the explanation about rand water vacancies in the article below.
Rand Water Vacancies to Get Clean Water
Raw water from water utilities originating from air sources cannot be directly used for buildings. The water must first meet the requirements of quality, quantity, and continuity. To maintain the quality of the air, usually, the air will undergo processing. This processing can be done in 3 ways: physics, chemistry, and biology. There are many rand water vacancies involved to produce clean water.
In many countries, they generally use water and chemical water treatment plants. Basically, processing the air is divided into 3 parts, namely:
1. Intake Development
As the name implies, this building is used as the first place for air to enter. This building is equipped with a bar screen that serves to filter objects in the air. Then the air will enter a large tub before being pumped to a water treatment plant.
2. Water Treatment Plant
One of rand water vacancies is the team that will do the water treatment plant. This is a job where they will install the main installation of clean water treatment. Are there some processing parts in the STP that make the air turn off. This activity also has some sections which are:
The first part we know is the coagulation bath. In this tank, the air will be destabilized from colloidal particles. The destabilization process can be carried out chemically by observing substances and by means of physics, namely by fast mixing), hydraulics and mechanically (stirring rods) so that alum mixes with the air.
The people in these rand water vacancies will do flocculation that consists of flocculation to form and enlarge floc. The process of the air will be stirred slowly so that the alum mixed in the air can connect dirt particles and a larger form of floc to make it easier to settle.
After the flock is formed (usually the form of mud), the air will enter the sedimentation basin where the heavier floc density will automatically settle in the bottom of the tub and clean air can separate from the mud.
After the water is clean from mud, the air will be filtered again to be completely clean by entering the filtration tub. Filtration tanks can use membrane technology, but can also be substituted with other media such as sand and silica gravel. This process is carried out with the help of gravity.
After the processing is complete, it is usually carried out a process which is the addition of chlorine, ozonation, UV, draining, and others to avoid the potential of germs and bacteria contained in the air.
After the water has been processed, water will be put into a temporary shelter in the reservoir before being distributed to homes and buildings. To drain water, HDPE and PVC pipes are usually used.
To save more on construction and operational costs, the Water Treatment Plant is built in a high area so that it can save the use of a water pump because it can flow with gravity. To reach a wider area, usually, the water will be accommodated in reservoirs in each area before being pumped to homes and buildings. After you’ve known the process of clean water, do you still want to apply in rand water vacancies?
