Water Treatment Plant is a system that is functioned to treat water from polluted raw water quality (influent) in order to get standard effluent quality that is desired/determined or ready for consumption.
Water treatment Indonesia, basically divided into several stages, namely:
1. Filtration and Precipitation
Filtering and settling aims to separate raw water from substances, such as: garbage, leaves, grass, sand and others based on the specific gravity of the substance.
Coagulation is the process of mixing chemicals into water so that impurities in the water in the form of suspended solids such as organic dyes, fine mud, bacteria and others can clot and settle quickly.
Flocculation is the process of floc formation as a result of the combination of colloids in raw water (river water) with coagulant. The formation of floc will occur well if the coagulant is added to the raw water (river water) then slow stirring is carried out.
After the process of coagulation and flocculation, the water is allowed to stand until all the lumps of dirt that occur settle. After the dirt settles the water will look clearer.
In the deposition process, not all lumps of dirt can be deposited. The large and heavy lumps of dirt will settle, while the small and light ones will still float in the water. To get really clear water, a filtering process must be carried out. Filtering is done by flowing water that has been deposited with impurities into a filter tank consisting of a silica sand filter or using membrane technology.
Provision of disinfectant (chlorine gas) in filtered water aims to reduce the concentration of bacteria in general and eliminate pathogenic bacteria (disease-causing bacteria).
The following is the water filter technology in the Water Treatment Plant:
Reverse Osmosis, Sea Water DesalinationTreatment, Brackish Water Treatment, Ultrafiltration Water Treatment, Mineral Water Treatment, Ozonation WaterTreatment, Demineralizer Water Treatment
Physical Parameters of Water
Physical parameters of water are usually seen from elements related to the human senses such as sight, touch, taste and smell, which include turbidity (turbidity), color, smell, taste and temperature. The treatment systems that are commonly used are the Sedimentation System, Filtration and the addition of disinfectants.
Chemical Parameters In Water
Chemical compounds that are often found in water are Fe, Mn, Ca, Mg, Na, SO4, CO3. If the water contains excessive chemical compounds (not included in safe consumption standards), the processing can be carried out with a filtration system using certain media such as the Reverse Osmosis system or Demineralier and Softener.
Biological Parameters in Water
The parameters are seen based on the presence of microorganisms in the water. If the number of micro-organisms in the water is excessive, it will usually interfere with health when consumed. Treatment can be carried out using a disinfectant or commonly used tools, such as Chlor injection, System UV and System Ozone (O3).
