The forward osmosis separation process is the spontaneous diffusion of water from the side with high chemical potential to the side with low chemical potential under the action of osmotic pressure. This separation process does not require external pressure, but relies on the osmotic pressure difference between the draw solution and the feed solution to achieve membrane separation spontaneously. There are several necessary conditions for the implementation of this process: (1) selective permeation membranes and membrane components that allow water to pass through and intercept other solute molecules or ions; (2) Extracting fluid that provides driving force; (3) Reconcentration route for the diluted extract. The forward osmosis technology has been successfully applied in the fields of concentrated brine treatment and zero discharge systems, as well as the separation and purification of special concentrated liquids. Effectively reducing energy consumption and pollution, making zero emissions a reality for the entire factory.

The forward osmosis membrane pool/forward osmosis intelligent integrated testing equipment developed and produced by Bona has more accurate data testing, higher stability coefficient, stronger functions, simpler operation, and low equipment failure rate, effectively improving experimental efficiency and supporting customization.

1. Membrane pool materials are resistant to pollution, corrosion, organic solvents, and high temperatures;

2. Easy to disassemble and simple in design, suitable for both laboratory use and forward osmosis membrane testing;

3. Low operating energy consumption and low investment cost;

4. Wide inlet conditions, stable water quality, high recovery rate, and concentrated water can directly enter the crystallizer without the need for high-pressure steam;

5. Low operating costs, high degree of automation in operation, modular design, small footprint, and short construction cycle.
