(III)System composition and core functions

1. Preprocessing system

The system integrates multimedia filtration, activated carbon filtration, softening treatment, and precision security filtration units, which can effectively remove sediment, suspended solids, colloids, organic matter, and residual chlorine from raw water, reduce water hardness, and intercept fine impurities. By optimizing the inlet water quality in advance, eliminating various pollution loads, stabilizing the back-end inlet conditions, comprehensively protecting the reverse osmosis membrane components, and avoiding membrane blockage, oxidation, and fouling.

2. Secondary reverse osmosis (RO) system

Adopting a two-stage imported high-pressure reverse osmosis membrane treatment process, utilizing the principles of high-pressure screening and permeation separation, the vast majority of dissolved salts, impurities, bacteria, and colloidal pollutants in water are intercepted step by step. After two-stage deep desalination, the water conductivity is significantly reduced, producing high-purity primary pure water, effectively reducing the back-end EDI processing load, and providing a stable and qualified inlet water source for the ultra pure water precision treatment process.

3. EDI Electrodeionization Precision Processing System

As the core refining unit of the entire equipment, the EDI module combines ion exchange and electric field migration principles to continuously remove trace ions remaining in the reverse osmosis effluent. Relying on an electric field to achieve continuous self regeneration of resin without the need for acid-base agents, it can stably produce 18M Ω· cm grade electronic grade ultrapure water for a long time. It is a key core unit for achieving high-purity, pollution-free, and continuous water production.

4. Terminal sterilization and filtration system

Configure a dual wavelength ultraviolet sterilization device and a terminal precision filter to perform terminal purification treatment on the refined ultrapure water. It can efficiently kill water microorganisms, decompose trace organic pollutants, intercept fine particulate impurities, completely eliminate secondary pollution of water quality during pipeline transportation, and ensure that the final effluent is sterile, high-purity, and clean.

5. Fully automatic intelligent control system

Adopting an integrated control scheme of industrial PLC and touch screen, real-time monitoring of core parameters such as equipment flow rate, pressure, water quality resistivity, conductivity, etc. Equipped with intelligent functions such as automatic start stop, automatic flushing, high and low pressure protection, water shortage protection, fault alarm, data recording and storage, etc., the equipment can achieve 24-hour unmanned fully automatic and stable operation, with simple operation and convenient maintenance.
