                            The organic combination of EDI technology and reverse osmosis technology is the key technology of the ultra pure water treatment equipment, which can achieve the continuous removal of salt, simple operation and maintenance, no pollution of acid and alkali. Polysilicon film and semiconductor device in the process of cleaning water to meet national the electronic grade water quality standard "18.2 trillion euro or more, the most effective process of water is pretreated with RO and EDI technology. Ultra pure water treatment equipment has been widely used in polysilicon cleaning industry. Typical process:
