The design of laboratory pure water system needs to comprehensively consider water quality standards, process flow, equipment selection, etc. to meet the differentiated needs of different experimental scenarios. Botai editor will take you to learn about relevant knowledge.

1、 Design principles and core components

1. Pipeline Network Design and Circulating Disinfection

Adopting a circulating water supply network to avoid stagnant water areas and ensure water quality stability. Configure an automatic disinfection module to suppress bacterial and biofilm formation.

2. Matching water quality grading with demand

Ordinary chemical experiments can use Grade II water, trace analysis, cell culture, etc. require Grade I ultrapure water, and glassware washing can be performed with Grade III or Grade I water based on experimental sensitivity.

3. Pure water preparation process

Basic treatment includes processes such as reverse osmosis, ion exchange, and continuous electrodeionization. The system integrates technologies such as ultraviolet oxidation and microporous filtration to reduce microorganisms and organic pollutants.

2、 Key subsystem design

1. The material of the water storage and distribution system water tank needs to be corrosion-resistant, and the capacity can be selected from 25-100 L to adapt to different laboratory sizes. The distributor supports multiple traffic modes and has flexible installation locations.

2. Real time monitoring of electrical resistivity for water quality monitoring and data management TOC、 Microbial and other indicators are automatically stored and supported for export. The touch screen interface simplifies operation, providing fault warning and consumable replacement prompts.

3、 Equipment selection and maintenance

1. Mainstream system comparison to Millipore series: suitable for high-throughput requirements, supporting integrated preparation of RO water and ultrapure water. Shuhuoquan system: multi-stage purification process, focusing on low cost and stability.

2. Consumables replacement and maintenance: Pre purification columns and purification columns need to be replaced regularly. The operation steps include pressure relief, dismantling old parts, and installing new parts. Reverse osmosis membranes need to be regularly flushed to extend their lifespan and avoid scaling.
