1. Solid liquid mixture concentration meter
2. Why is a flow monitoring device added to the total return water outlet of the purified water system
When designing the purified water system, the flow rate of the purified water in the pipeline should be considered. Under normal water supply conditions, the purified water flow rate in the return pipeline is generally the lowest speed in the system pipeline. Research has shown that when the purified water flow rate is less than 0.9144m/s, it will be retained on the inner wall of the purified water pipeline, and there is a high chance of producing microorganisms. Therefore, a flowmeter is added to the return pipeline for monitoring to confirm that the return water flow rate is greater than 0.9144m/s.
3. Hospital Central Pure Water System
The hospital central pure water system can be understood as the core module designed for medical pure water demand in the hospitals central quality water supply system. Its essence is to provide pure water that meets medical standards for different departments through centralized water production and quality water supply mode, combined with multi-level water treatment process and intelligent control system.
. The following is a specific analysis:1. System Definition and Core Functions The hospitals central quality water supply system integrates pre-treatment, reverse osmosis, EDI (electrodeionization), ultraviolet disinfection and other processes to convert municipal tap water into medical water of different purity levels (such as purified water and injection water), and transports it to various departments through a circulating pipeline network.
. Its core functions include centralized water prod
II. System Composition and Operation Logic: Pre treatment Stage of Water Treatment Process Module: Remove suspended solids, residual chlorine and other impurities through sand filtration and activated carbon filtration.
. Core processing stage: Reverse osmosis (RO) technology: removes over 95% of soluble salts and microorganisms. EDI module: further desalination to produce purified water with a resistivity of ≥ 15M Ω· cm. Post processing stage: UV sterilization and ozone disinfection ensure sterile water quality at the terminal. The circulating water supply network adopts 304/316L stainless steel pipes to form a closed-loop circulation system and avoid stagnant water areas. Equipped with pressure sensors and flow meters, dynamically adjust the water supply pressure to ensure stable pressure at the water point. Intelligent control system operates fully automatically: automatically adjusts parameters such as reverse osmosis membrane cleaning cycle and EDI current based on water quality testing results. Safety interlock: When the water quality exceeds the standard (such as conductivity>1 μ S/cm), the water supply will be automatically cut off and an alarm will be triggered. Network visualization platform: Real time display of data from various links through IoT
