How does reverse osmosis work to obtain clean drinking water?
The water passes through a pre-filter to remove sediment and larger particles. It is then forced through a membrane that is designed to allow it to pass through, while keeping pollutants contained on the other side of the membrane. The contaminants are sent down the drain with the wastewater. You need to have decent water pressure in your house for the treatment system to work effectively. Reverse osmosis is the most effective of all drinking water treatments systems. Each type of filtering system removes specific contaminants. RO systems remove a wider variety of pollutants than other methods. These filters use a porous membrane to strain very fine particles. The number of chemicals, microorganisms and pollutants removed by this process is large. These systems work effectively by removing 99% of chlorine, fluoride, iron, lead, and organisms such as giardia, e-coli and cryptosporidium.
