This time we will discuss about "Water Treatment Plant (WTP) or Water Treatment Plant (IPA)", which is a building or main construction of a clean water treatment system. In clean water treatment, in general, there are 3 buildings or constructions, namely: Intake, Water Treatment Plant (WTP) or Water Treatment Plant (IPA), and Reservoir. Intake Intake is the first building or construction for the entry of water from a water source. In this Intake building or construction, there is usually a bar screen that functions to filter out objects that are also inundated in the water. Then the water will be pumped to the next building or construction, namely the Water Treatment Plant (WTP). Water Treatment Plant (WTP) or Water Treatment Plant (IPA) Water Treatment Plant (WTP) or Water Treatment Plant (IPA) is a system or facility that functions to treat water from contaminated raw water (influent) quality to get the desired water quality treatment according to quality standards or ready for consumption. Water Treatment Plant (WTP) or Water Treatment Plant (IPA) is an important facility around the world that will produce clean and healthy water for consumption. Usually this building or construction consists of 5 processes, namely: coagulation, flocculation, sedimentation, filtration, and disinfection.
