Bipolar reverse osmosis host

Reverse osmosis device

The reverse osmosis host is mainly composed of a booster pump, membrane housing, reverse osmosis membrane, control circuit, etc. It is the core part of the entire water treatment system, and the quality of the produced water mainly depends on this part. As long as the membrane model and booster pump model are selected properly, the reverse osmosis host can achieve a filtration capacity of over 99% for salt in water, and the effluent conductivity can be guaranteed to be within 10us/cm (25 degrees).

Place dilute solutions (such as fresh water) and concentrated solutions (such as seawater or saltwater) of the same volume on both sides of a container, separated by a semi permeable membrane in the middle. The solvent in the dilute solution will naturally pass through the semi permeable membrane and flow towards the concentrated solution side. The liquid level on the concentrated solution side will be higher than that of the dilute solution by a certain height, forming a pressure difference and reaching osmotic equilibrium. This pressure difference is the osmotic pressure. The magnitude of osmotic pressure depends on the type of concentrated solution, and the concentration and temperature are independent of the properties of the semi permeable membrane. If a pressure greater than the osmotic pressure is applied on the concentrated solution side, the solvent in the concentrated solution will flow towards the dilute solution, and the flow direction of this solvent is opposite to the original direction of permeation. This process is called reverse osmosis.
