Any technique that enhances the quality of water to make it suitable for a certain end-use is known as water treatment. Drinking water, industrial water supply, irrigation, river flow maintenance, water enjoyment, and a variety of other applications are possible, as well as being properly returned to the environment. Water treatment removes or reduces the concentration of pollutants and unwanted components in order to make the water fit for its intended purpose. This therapy is essential for human health since it allows people to benefit from both drinking and irrigation. This treatment aids in the production of safe, tasty, clear, colourless, and odourless water. Water must also be non-corrosive, which means it must not harm pipes.

Water is a crucial component in production. Water is essential in industry, and it must adapt to the various needs of various operations. Industrial water includes everything from cooling and boiler feed water in power plants to process water for a variety of industrial applications, as well as ultrapure water for the electronics and pharmaceutical industries. Raw water treatment systems are used to pre-treat and optimise source water, with the goal of increasing production efficiency and process performance for a specific application. Pre-treating cooling tower/boiler feed water, process/production water, and/or drinking water are examples.
Raw water treatment is frequently focused on protecting downstream equipment against pollutants in the source water that cause scaling, fouling, corrosion, and other types of damage or premature wear. Suspended/colloidal particles, silica/colloidal silica, iron, bacteria, and hardness are commonly removed by raw water treatment systems.
Below is a flowchart with described steps, representing several processes included to make water perfect for industrial use:
Intake: Gravity and/or pumps are used to bring raw water into a plant. To keep heavy things out of the system, the water is frequently routed through a metal grate or mesh screen.
Clarification: The water then goes through a multistep clarifying procedure to remove suspended particles from a solution. Coagulation, in which chemical and/or pH modifications lead particles to clump together, is followed by flocculation, in which physical movement encourages the production of bigger particles. The stream next runs to a gravity settler, where sediments settle to the bottom in what is known as a sludge blanket. Finally, a gravity sand filter is used to catch any minute particles in the stream.
Disinfection: If biological pollution and/or water potability are issues, the water can be disinfected to eliminate microorganisms. Chemical disinfectants (such as chlorine), physical disinfectants (such as UV or heat), and some types of membrane filtration can all be used to disinfect water.
Lime softening: It is a term used to describe the process of a lime in streams with significant mineral or sulphate concentration, a lime softening step may be added to minimise hardness. The procedure involves adding lime or lime soda to the stream to elevate the pH, which causes mineral components to precipitate out of solution.
Ion Exchange: An IX unit for hardness removal or other particular treatment needs may be included in the raw water treatment system in some situations. A stream is channelled through a strong acid cation resin that has been "charged" with sodium; as the water passes through, the resin collects the hardness-causing calcium or magnesium ions while releasing sodium ions into the stream.
Distribution: The water is pumped or otherwise directed for use elsewhere in the facility after treatment.
Industrial water includes everything from cooling and boiler feed water in power plants to process water for a variety of industrial applications, as well as ultrapure water for the electronics and pharmaceutical industries, some of the processes are added or eliminated as per the requirements of the industry.
