Purified water is produced through a carefully-monitored and regulated process that ensures its quality is suitable for human consumption. The treatment process begins with pre-treatment, which includes collecting water from the source, such as a lake, river, or well. This water then undergoes filtration to remove coarse particles such as sand and grit. After this stage, the water then moves on to chemical processes like coagulation, flocculation, and disinfection using chlorine or ozone. At the final step of the tissue process, special equipment may be used to refine it further, such as reverse osmosis systems or deionization systems.
