RO (Reverse Osmosis) technology is a technology made from a membrane that has a high flux which is operated at low pressure to convert brackish water into fresh so that in its use, the membrane is very easily damaged and causes more water to be wasted due to excessive pressure. RO technology has another disadvantage; it requires a multilevel membrane with larger dimensions to produce maximum results. Therefore, it is necessary to innovate RO technology that has a long RO membrane lifetime, practical dimensions and saves raw water. Incoming water flow will be controlled at 0.5 L/m to prevent membrane damage. The salinity of the product water is set to less than 500 ppm and turbidity to less than 25 NTU. The plant will turn off automatically when the product tank level reaches 20 cm. The results of this study will be used as an advance in the science of making WTS with the RO method and can also be a teaching aid for the use of brackish water into freshwater.
