Solar energy is a type of renewable energy with characteristics such as large reserves, clean and pollution-free, renewable, and on-site availability. Therefore, promoting the development of the new energy field, especially the photovoltaic industry, has become a consensus among countries around the world. At present, the main production resources of the domestic solar photovoltaic industry are concentrated in: polycrystalline silicon purification, pulling single crystals, polycrystalline silicon ingots, slicing, solar cells, modules, etc. The main power requirements in these production processes include ultrapure water, power supply, and special gas.

Polycrystalline silicon must undergo strict cleaning with ultrapure water to improve its material properties compared to others, and contamination may lead to performance degradation. The purpose of using ultrapure water for polycrystalline silicon is to clean the impurities on the surface, including organic matter, inorganic matter, and other ions. If ultrapure water cleaning is not suitable, it may cause leakage and lead to various performance defects. Therefore, ultrapure water is necessary for cleaning polycrystalline silicon and photovoltaic panels. Currently, the process of producing ultrapure water can be divided into reverse osmosis equipment and reverse osmosis+EDI ultrapure water equipment, which are two commonly used processes for producing ultrapure water equipment. Polycrystalline silicon has high requirements for water quality, with a resistivity of over 18 megawatts.

Literide has been dedicated to the production process of ultrapure water for many years, and ultrapure water equipment is widely used in chip production due to its significant advantages. Ultra pure water equipment combines reverse osmosis membrane separation technology and EDI technology to prepare ultra pure water. Compared with traditional processes, this process has low operating costs and reliable operation. It has a high degree of integration, is easy to expand, and increasing the number of membranes can increase the processing capacity. High degree of automation, automatic shutdown in case of malfunction, with automatic protection function. The membrane module is made of composite membrane rolls and has high solute separation and permeability. Low energy consumption, high water utilization efficiency, and low operating costs.

The Literide ultra pure water equipment adopts pre-treatment, reverse osmosis technology, EDI technology, and post-treatment methods to almost remove conductive media and non free colloidal substances from water, with low gas and organic content in the water. The Literide ultra pure water equipment has the advantages of continuous effluent, no acid and alkali regeneration, unmanned operation, simple installation, and easy operation. The effluent quality meets the relevant standards of the semiconductor industry.

Literide has multiple core technologies for ultra pure water specialized membranes, which are used to prepare cleaning water for high-precision machinery, silicon wafers, scientific research instruments, and other products, providing users with high-quality ultra pure water!
