In 1974 Congress passed the Safe Drinking Water Act (SDWA) that set forth specific water quality standards, required monitoring for contaminants and required water suppliers to submit data and water quality reports that would be available to the pump. Since then many changes have been made to the SDWA – primarily related to adding additional parameters to be monitored and regulated. Many of these regulated contaminants are difficult to treat with conventional softening or filtration treatment technologies. Membrane treatment has become invaluable to help cost-effectively meet these increasing regulations for contaminants such as metals, fluoride, radionuclides, organics/trihalomethane precursors, and more. The ion rejection characteristics of reverse osmosis membranes makes them likely to be able to continue to meet more stringent water quality treatment goals – whether federally mandated or voluntarily adopted on a local level.
The federal government identifies Best Available Technologies for addressing regulated contaminants. Reverse Osmosis is listed as the Best Available Technology for twelve out of the seventeen regulated inorganic chemicals. It is the only water treatment technology designated as ideal for treating that many of the regulated chemicals. Reverse Osmosis is also the only designated Best Available Technology for removing combined radium, uranium, gross alpha and beta and photon radioactivity.
Membrane treatment is known as the first choice for salinity reduction for brackish water treatment, it is also cost-effective for softening and color and organic removal. Keep in mind it can be the best choice for other new regulations as well. Please contact Harn R/O for further information about what membrane treatment can do to meet your water treatment needs.
