We provide fully containerized/mobile reverse osmosis water treatment systems, which are assembled in containers that meet ISO standards. Each container is customized according to specific water treatment applications and has the characteristics of easy installation and operation, high efficiency, small footprint, energy saving and environmental protection.
Brackish & Seawater Treatment System includes multi-media pre-filters, water softeners or antiscalant dosing systems, dechlorination dosing systems, reverse osmosis devices with semi-permeable membranes, and ultraviolet disinfection devices or post-chlorination equipment as post-treatment. These RO units use reverse osmosis technology to first send the incoming water to a multimedia pre-filter to remove particles larger than 10 microns. Next, antiscalants are injected into the water to control hardness fouling that can damage the RO unit membrane. These pre-treatment solutions can remove hardness, chlorine, odor, color, iron and sulfur. The water then enters the RO unit, where a high-pressure pump applies extremely high pressure to the highly concentrated solution to separate out the remaining salts, minerals and impurities that the pre-filter failed to capture. Fresh drinking water flows out of the low-pressure end of the membrane, while salts, minerals and other impurities are discharged from the drain at the other end. Finally, the water passes through a UV sterilizer (or post-chlorination) to kill any remaining bacteria and microorganisms in the water.
Brackish & Seawater Treatment System are cost-effective and use the latest RO technology to remove dissolved salts, particles, organic matter, minerals, tannins, solids and other impurities from the water. Brackish Water RO System manufacturers use RO membranes as the core separation technology to block these impurities. FupengWater uses products from many of the world's leading Brackish & Seawater Treatment System manufacturers.
As part of our Brackish line, RO units have capacities ranging from 1 – 500 m³/h with feed water total dissolved solids (TDS) concentrations ranging from 900 to 5,000 ppm. These RO units come standard with pre- and post-treatment components. In addition, we offer customization options such as higher feed water TDS, lower water temperatures, future expandability, variable pressure designs with VFDs, BMS system outputs, data logging, and remote monitoring.
