The mobile RO system is a cart-mounted system that can be installed anywhere there is a water supply. The system draws water with a raw water pump and sends it through sand and carbon filters, a pressurized sand filter to remove turbidity, an activated carbon filter to remove odors and colors, and an antiscaling agent to be injected into the reverse osmosis system. With its help, the membrane does not clog. The system includes a PLC base for the electrical panel and instrument panel. Mobile RO is cart-based and can be moved from one location to another.
