Service Water TreatmentĀ involves various procedures that separate the various types of contaminants from the water. During the water treatment process, water is made slightly basic so that the metals that are present in the water will be precipitated. This process also removes organic matter. It is an ancient technique that was used by the Romans and Egyptians. It is one of the most common methods in water treatment. It is also one of the most common processes used to remove the suspended solids from wastewater.
During the different processes, different chemicals are added to the water to achieve the desired results. These chemicals may include disinfectants, corrosion inhibitors, and pH balance agents. These chemicals are required to meet specific standards set by the EPA. The process is highly effective at removing many kinds of bacteria and viruses from water. The EPA’s site contains more information about water treatment. Its effectiveness is dependent on the raw water quality and seasonal variations. For example, water that is highly contaminated with microbial pathogens and has a high coliform count may require pre-treatment before undergoing conventional treatment. For low coliform counts, however, conventional treatment is sufficient.
Water treatment can also include biological processes or mechanical methods. Water treatment is essential to ensure that water is safe for human use and meets environmental standards. The process relies on science and engineering to ensure that the technology works as intended. The art of presenting a clean, safe water source is also important in the water treatment process. Some of the most common technologies for water treatment include ultraviolet irradiation, disinfection, and ozonation. In addition to disinfection, water treatment can also remove suspended particles that can harm human health.
The process of water treatment starts with flash mixing of the primary coagulant and polymer. After that, the water is put into a flocculation basin where it is turned slowly. The mixture of the chemicals creates a coagulate or floc which settles at the bottom of the flocculation basin.
Water treatment technologies for potable water are well developed. Many private companies offer patented technological solutions for a variety of contaminants. In the developed world, water treatment is often automated. However, capital and operating costs can be influenced by the source water’s quality. The end-use of treated water can also determine the quality monitoring technologies needed. The degree of automation required can also depend on local skills and availability.
Public drinking water systems use a combination of different water treatment methods. Some of these methods include coagulation, sedimentation, filtration, and disinfection. The coagulation process is often the first step in water treatment, and it involves adding chemicals with a positive charge to the water. The chemicals then adhere to dissolved particles and form larger particles. Common chemicals used in this process include specific salts and aluminum.
The next step of water treatment is flocculation. This process involves gently stirring the water to create larger, heavier particles. This step is followed by sedimentation, which involves the sedimentation of the flocs. During sedimentation, the flocs settle to the bottom of the water supply. There, they are then removed from the water.
