What is the process of water treatment industry? ›
The process involves the application of lime or lime soda to raise the pH of the stream, which in turn encourages mineral constituents to precipitate out of solution. Ion exchange (IX). In some cases, the raw water treatment system may include an IX unit for hardness removal, or other specialized treatment needs.
What are the primary water treatment processes? ›
Primary Treatment
As sewage enters a plant for treatment, it flows through a screen, which removes large floating objects such as rags and sticks that might clog pipes or damage equipment. After sewage has been screened, it passes into a grit chamber, where cinders, sand, and small stones settle to the bottom.
