The application of industrial reverse osmosis water treatment equipment (membrane separation) technology makes the reverse osmosis ultra pure water equipment get a progress from the traditional cation exchanger, decarbonization, anion exchanger, composite school drinking water equipment ion exchanger. In recent years, EDI (electrodeionization) technology, which has been popularized and applied abroad, is a revolution in ultra-pure water manufacturing technology. Since then, it has entered into a new industry, which can produce ultra-pure water up to 18M CM without regenerative chemicals, and is used in semiconductor, integrated circuit and other industries. The State Commission for Rural Drinking Water Equipment has also included the application of RO + EDI technology in the national key promotion scope, giving preferential policies to the enterprises used.

Reverse osmosis (membrane separation) ultra-pure water manufacturing technology: Reverse osmosis (RO) is the separation of solvent (commonly referred to as water) in solution through a reverse osmosis membrane (a semi-permeable membrane) under sufficient pressure. The direction is opposite to the osmosis direction. It can be used to separate, purify and concentrate the solution by reverse osmosis method greater than the osmotic pressure. The main separation object of reverse osmosis membrane is the ionic range in solution.
