Sea Water Reverse Osmosis (SWRO) is one of the most widely used and efficient desalination technologies for converting seawater into fresh potable or process water. The process operates by applying high pressure to seawater and forcing it through specialized semi-permeable membranes that allow water molecules to pass while rejecting dissolved salts, minerals, bacteria, viruses, and other impurities. Since seawater typically contains approximately 45,000 ppm of dissolved salts, significant pressure is required to overcome the natural osmotic pressure and achieve effective separation
A typical SWRO system consists of several key stages. Initially, seawater undergoes intake and pretreatment processes, which may include screening, filtration, dissolved air flotation (DAF), ultrafiltration (UF), or media filtration to remove suspended solids and protect the membranes from fouling. Following pretreatment, high-pressure pumps feed the water into reverse osmosis membrane modules where desalination occurs. The membrane system separates the feed water into two streams: permeate (treated fresh water) and concentrate (brine reject stream). Post-treatment processes such as pH adjustment, remineralization, and disinfection are then carried out to ensure that the produced water meets drinking water or industrial quality requirements.
AquaSwiss SWRO plants are highly energy-efficient due to the integration of energy recovery devices (ERDs) and a numbe of Process, Material and Membrane Optimization aspects adopted by us. We are deemed to be the Lowest Carbon Footprint technology in desalination by Swiss Federal Ministry
Our Combination of technology, several hundred man-years of experience on team and pre-fabricated trains in cost effective area of Europe allows us to offer SWRO plants at extremely competitive prices while maintaining Swiss/ European quality standards.
We are open to offering warranties on long term operational costs. Our SWRO technology is extensively used for municipal drinking water production, industrial applications, power plants, and remote communities, particularly in regions with limited freshwater resources. We keep pace with continuous improvements in membrane technology and energy optimization by collaborating with the very best suppliers.
We are able to couple our SWRO offering with Financial Solutions such as BOO and EPC-F models.
Brackish Water Reverse Osmosis (BWRO) System
We offer Brackish Water Reverse Osmosis (BWRO) also from basic to advanced cases of chemistry of water from simple well water to removal of multiple scaling components and chemicals in an industrial environment. Brackish water generally has a salinity range between 1,000 and 15,000 ppm Total Dissolved Solids (TDS), which is significantly lower than seawater. BWRO systems utilize similar membranes and pressure-driven separation processes to remove dissolved salts, organic compounds, suspended solids, bacteria, and other contaminants as in SWRO.
A typical BWRO system consists of several stages including water intake, pretreatment, reverse osmosis desalination, and post-treatment and we can offer recoveries exceeding 90%.
