The forward osmosis separation process is the spontaneous diffusion of water from the side with higher chemical potential to the side with lower chemical potential under the action of osmotic pressure. This separation process does not require external pressure but is achieved spontaneously through the osmotic pressure difference between the draw solution and the feed solution, enabling membrane separation. The realization of this process requires several necessary conditions: (1) a selective permeable membrane and membrane module that allows water to pass through while retaining other solute molecules or ions; (2) a draw solution that provides the driving force; (3) a re-concentration pathway for the diluted draw solution. Forward osmosis technology has been successfully applied in the treatment of concentrated brine and zero discharge systems, as well as in the separation and purification of special concentrated solutions. It effectively reduces energy consumption and reduces pollution, making full plant zero discharge a reality.
The positive permeation membrane pool and positive permeation intelligent integrated testing equipment developed and produced by Wuhan Bona have more accurate and stable data testing results, higher functionality, simpler operation, lower equipment failure rate, effectively improving the experimental efficiency, and supporting customization.
The membrane pool material is resistant to pollution, corrosion, organic solvents and high temperatures.
2. The easy-to-assemble design is elegant and simple. It is not only suitable for laboratory use but also can be used for the testing of reverse osmosis membranes.
3. Low operating energy consumption and low investment cost;
4. The water intake conditions are broad, the water quality of the produced water is stable, and the recovery rate is high. The concentrated water can be directly fed into the crystallizer without the need for high-pressure steam.
5. Low operating costs, high degree of automation in operation, modular design, small floor area, and short construction period.
