How Spectra desalination worksReverse osmosis is a process that converts seawater or contaminated water into fresh, portable water by removing dissolved salts and harmful substances. The seawater membranes filter out salt, bacteria, viruses, protozoa, and cysts, producing clean drinking water.
Spectra's unique energy recovery technology controls pump pressure through the membrane, allowing our systems to operate at lower pressures than conventional systems, improving energy efficiency, extending membrane life, and reducing the need for descaling.
Reverse osmosis removes up to 99% of dissolved solids, making it ideal for purifying water in marine and remote environments. Spectra's innovative design minimizes energy consumption while ensuring optimal desalination performance in energy-limited settings. |
