Abstract :
Background and purpose: Purified water is one of the most important elements in the health of human societies, so trying to purify water through water treatment plants is justifiable even with high costs. Surface waters often have a greater variety of pollutants than underground waters, and for this reason, treatment processes may be more complicated for such waters. In water treatment plants, the purification process starts through the inlet pipe to the treatment plant and enters the urban water stream by passing through garbage collection structures, aeration, microstrainer, rapid mixing, superpulsator, sand filter and tank. Like the concentrator, the recycling tank and the contaminated mechanical dewatering are divided into two parts that can be treated and cannot be treated, and the non-degradable solids are directed out of the tank.
Research method: This article has investigated the construction method and performance of different parts of water treatment plants in an executive and scientific way by reviewing reliable scientific databases and the experiences of the authors.
Findings: The performance of different parts of the treatment plant and their construction methods have been analyzed and the importance and position of each part has been discussed.
Discussion and conclusion: The process of water purification from the time of entering the water treatment plant to the time of its exit was investigated in detail, including the construction method, which provides useful information for planners, designers and activists in this field
