Reverse Osmosis
One way to process waste streams into mineral concentrate is through Reverse Osmosis. Circular Values Industries' Reverse Osmosis plant works on the principle of membrane filtration using (high) pressure. Dissolved particles cannot pass through the membrane. So these particles such as ions, viruses, bacteria and other dissolved substances are stopped and enter a concentrated stream. Only water is allowed to pass through the membrane. The outgoing streams from the process are thus a mineral concentrate on the one hand and dischargeable “clean” water on the other. The mineral concentrate that remains may be used as a fertilizer substitute.
The High Pressure Reverse Osmosis (HPRO) from Circular Values industries is modular, meaning that in addition to the pressure tube with membrane, the unit can also be supplied with various pre-filter systems and optionally a manure separator to separate the manure into thick fraction and thin fraction. Each CVI HPRO also optionally includes an automated Cleaning In Place (CIP) system, which cleans the membranes within the system itself.
A regular Circular Values Industries RO has a working pressure of 60 bar, but in some situations this is not enough to dewater the residual stream sufficiently. In these cases, we offer a specially developed Circular Values Industries High Pressure Reverse Osmosis (HPRO). This can be supplied in 100, 120 or 160 bar versions. The pressure tubes are manufactured to withstand these high pressures and the valves and metering technology are of industrial quality. In addition to the working pressure, the RO units are also available in different capacities. Due to the modular features of the system, the capacity can be scaled up to meet your situation. In an industrial environment, several RO systems with different pressures can also be switched back to back. High quality membranes are installed in the pressure tubes to achieve high dewatering and produce a clean permeate.
