Reverse osmosis water treatment is a standard process used in areas where water supply comes from brackish water. Estuaries, lakes, bays, and lagoons in the country are the most common sources of this type of water. As a product of its environment, brackish water needs to be effectively treated to be safe for human use, and reverse osmosis is known to be an effective treatment method.
What does Reverse Osmosis remove?
An RO system effectively eliminates water impurities that are larger than its membrane pores (approximately 0.0001 micron in size). Among the minute particles removed are microbes, including Giardia, E. coli, Salmonella, Hepatitis A, and Rotavirus. Aside from these parasites, bacteria and viruses, hard minerals, and chemical contaminants are also filtered out. The treated water will also have significantly reduced harmful particles like arsenic, radium, and excess salts.
Is RO water safe for drinking?
Technically, RO water is safe to drink. Supplied to homes as tap water, brackish water treated by RO is, by itself, clean, but any impurities along the supply system and residential pipelines can diminish the cleanliness. Residential reverse osmosis systems are also available to further filter tap water in homes. Supplementation can also replenish the minerals lost during filtration.
However, some brackish water sources may be more contaminated than others, especially those more exposed to industrial or environmental wastes. Water chemistry analysis need to be done to determine the right RO specs, as well as the water quality that can be expected after the treatment.
