Pure water scheme for reagent preparation
Release date: 09:38:16, December 2, 2019
Pure water for chemical reagent configuration is mainly used in battery solvent, chemical analysis, chemical materials, product cleaning, material separation, concentration, purification, waste recovery and other occasions. The water quality requirements are relatively not too high. The conductivity of pure water from 0.1us/cm-20us/cm can basically meet the requirements. According to the specific requirements of customers for water quality, our company can adopt different combinations of ultra pure water production processes such as reverse osmosis, ion exchange and EDI to produce pure water equipment that is economical and practical and can meet the requirements of customers.
The water purifier process of chemical reagent configuration is roughly divided into the following categories:
1. The process is as follows:
Raw water → raw water pressure pump → multi-media filter → activated carbon filter → water softener → precision filter → cation resin filter bed → anion resin filter bed → anion and cation resin mixed bed → microporous filter → water consumption point
2. Two stage reverse osmosis is adopted, and the process is as follows:
Raw water → raw water pressure pump → multi-media filter → activated carbon filter → water softener → precision filter → first stage reverse osmosis → pH regulation → intermediate water tank → second stage reverse osmosis (reverse osmosis membrane surface with positive charge) → purified water tank → pure water pump → microporous filter → water consumption point
3. EDI mode is adopted, and the process is as follows:
First stage filter → medium filter → medium filter → water pump
Characteristics of water purifier with chemical reagent configuration
The pure water machine for chemical reagent configuration is usually prepared by ion exchange resin, but the use of ion exchange resin usually requires frequent resin regeneration, which is a waste of material resources and labor. After years of practice and combined with the latest membrane separation technology, our company often adopts the combination of reverse osmosis and ion exchange system (or EDI) to prepare ultra pure water Compared with the traditional ion exchange process, the operation cycle of the ion exchanger is greatly prolonged. Compared with the latest technology, it has the advantages of low cost and easy access to consumables. Reverse osmosis technology is advanced and reliable.
