RO is used to remove dissolved solids and contaminates from water used in both commercial and industrial applications by applying pressure to move water through a semi-permeable membrane.

In comparison to other methods of filtration such as nanofiltration, ultrafiltration or microfiltration, reverse osmosis can effectively remove contaminants as small as 0.0001 microns, including salts, ions and other materials.

RO systems can be used to remove low-molecular-weight resins and dissolved salts from things like electrocoat paint ultrafiltrate and can play a major role in reducing the consumption of DI water and generating less wastewater. It can be used to create a closed-loop system for a variety of surface finishing applications.

In electrocoat applications, it is not uncommon for a process to use a 2nd stage pass of RO in order to polish the product within tight tolerances. Afterwards, the water can be re-used in any part of the cycle. The systems can also help electrocoaters with paint recovery, reducing amount of wasted paint...READ MORE.
