    Seawater Purifier from NEWater

    NEWater seawater purifiers perform the purification work in three stages. Firstly, the pre-treatment method separates solids, seaweeds, and other coarse elements from the seawater. Then, the treated water is propelled through semipermeable membranes for the isolation of sodium chloride or salt, ions, and microorganisms. Pre-treatment is crucial so that the 0.0001-micron pores do not get clogged.

    Finally, the water passes through a post-treatment stage for maintaining the pH balance and making the water ready for consumption. Our seawater purifiers can further adjust minerals in the water to replenish dietary deficiencies in humans.

    Our seawater purifiers primarily work on reverse osmosis technology. However, we also manufacture ultrafiltration and Nanofiltration seawater purifiers.

    So, if you are looking for the most powerful and budget-friendly seawater purifier, call NEWater today!
