Reverse Osmosis Treatment Process

Reverse osmosis is the process of forcing water through a semipermeable membrane to reduce impurities and additional contaminants. It does this in four separate stages. To begin, pressurized water passes through a particle filter to remove salt, sand and sediment. The water then moves through an activated carbon filter, which traps minerals and contaminants such as chlorine, mercury, copper and pesticides. The pressurized water is pushed through the semipermeable membrane where the smallest impurities are removed. In the final stage of reverse osmosis, contaminants are flushed away as the treated water moves to a storage tank and undergoes a final activated-carbon filtration to improve quality before use.
