How should semiconductor ultrapure water equipment be cleaned? In the semiconductor industry, ultra pure water equipment adopts advanced reverse osmosis treatment technology and post purification technology to ensure that the effluent quality meets the requirements of ultra pure water. The equipment is made of advanced stainless steel material, which has strong corrosion resistance and will not cause rusting problems.

Working principle of semiconductor cleaning ultrapure water equipment

The Edi module is divided into cationic and anionic resins, in which the concentrated water is converted into pure or ultrapure water through ion exchange method (depending on the filtration level of the resin). The electrical resistivity of EDI pure water can reach up to 18MQ. cm (25 ℃), but according to the purpose of deionized water and system configuration settings, EDI pure water is suitable for preparing electrical resistivity requirements between 1-18 2 megaohms. cm (25 ℃).

Preparation process of ultra pure water equipment for semiconductor cleaning

1. Pre treatment system, reverse osmosis system, intermediate water tank, coarse mixing bed, fine mixing bed, pure water tank, pure water pump, ultraviolet sterilizer, polishing mixed bed, precision filter, water point.

2. Pre treatment reverse osmosis intermediate water tank water pump ED1 device purification water tank - spicy water system - ultraviolet sterilizer - along with light irrigation bed 0 2 or 0.5 μ= Precision filter water point.

3. Pre treatment first stage reverse osmosis dosing machine (pH regulation) middle water tank second stage reverse osmosis (positively charged reverse osmosis membrane) pure water tank pure water pump EDI device ultraviolet sterilizer 0 2 or 0.5 μ M precision filter water point.

4. Pre treatment reverse osmosis intermediate water tank water pump EDI device pure water tank pure water pump ultraviolet sterilizer 0 2 or 0.5 μ= Precision filter water point.

5. Pre treatment system, reverse osmosis system, intermediate water tank, pure water pump, phase mixing bed, fine mixing bed, ultraviolet sterilizer, precision filter, and water point.
