What is the first stage of treatment in a water treatment plant?
In the first stage, the still completely untreated wastewater is mechanically treated; this removes about 20 – 30% of the contained solids. To achieve this, the wastewater is guided into a screening plant, where a screen or sieve drum filters out coarse impurities such as leaves, paper or textiles.

What are the three main stages of water treatment?
There are three main stages of the wastewater treatment process, aptly known as primary, secondary and tertiary water treatment. In some applications, more advanced treatment is required, known as quaternary water treatment.
What is the most important step in water treatment?
It is, however, an important primary step in the water treatment process, because coagulation removes many of the particles, such as dissolved organic carbon, that make water difficult to disinfect. Because coagulation removes some of the dissolved substances, less chlorine must be added to disinfect the water.

Screens or sieves are great for straining larger particles out of water and are a simple, but flexible technology for diverse configurations. … They can be placed at surface water inlets to prevent debris or coarse material from reaching subsequent treatment processes.
Community Water Treatment
Water Fluoridation
- Community water fluoridation prevents tooth decay safely and effectively. Water fluoridation has been named one of 10 great public health achievements of the 20th century 1. For more information on the fluoridation process and to find details on your water system’s fluoridation, visit CDC’s Community Water Fluoridationpage. Top of Page
Consumer Confidence Reports
- Every community water supplier must provide an annual report, sometimes called a Consumer Confidence Report, or “CCR,” to its customers. The report provides information on your local drinking water quality, including the water’s source, contaminants found in the water, and how consumers can get involved in protecting drinking water. 1.
