Portable seawater desalination machine

With nearly 97% of Earth’s water locked in the oceans, access to fresh, potable water remains one of humanity’s greatest challenges. Over 2 billion people still lack safely managed drinking water, while only 1% of global freshwater is readily available for human use.

Seawater desalination offers a vital solution - transforming saltwater into high-quality drinking water through advanced reverse osmosis (RO) technology. While most desalination methods are energy-intensive, expensive, or immobile GOODWATER Solutions seawater RO desalination systems utilize premium membranes from leading international brands, achieving a salt removal rate exceeding 98% and a filtration precision finer than 0.0001 microns.

These membranes efficiently remove salt, organic compounds, bacteria, and microorganisms, delivering water that meets international drinking water standards. Each system integrates a high-pressure pump designed specifically for seawater applications, along with high- and low-pressure protection devices to ensure safety, reliability and long-term operational stability. The result is an energy-efficient, high-performance desalination unit that provides consistent output - even under challenging marine conditions.
