Purified water equipment for medical device cleaning is an efficient, reliable, safe, energy-saving, and environmentally friendly medical water treatment device. Most pharmaceutical companies at home and abroad use pre-treatment+reverse osmosis and EDI combined methods to produce purified water, and extract injection water through distillation. The reverse osmosis membrane achieves a 100% removal rate for microorganisms, pyrogens, viruses, and organic matter in water. Although secondary reverse osmosis can eliminate the need for ion exchange resins, it requires extremely high salt content in the raw water. The requirements for water quality in pharmaceutical pure water are more stringent and high, and the resistance value of ultrapure water is often required to be higher than 15 megabytes. Starting from the characteristics of ultra pure water used in the entire pharmaceutical industry, our factory has adopted new processes such as reverse osmosis and EDI to design a targeted set of high-purity water treatment processes to meet the requirements of pharmaceutical factories, hospitals for purified water production, and large infusion water production.
The pure water quality standards for biopharmaceutical purified water equipment (medical water treatment equipment) are mainly based on the 2020 edition pharmacopoeia standards and GMP standards, including indicators such as resistivity, conductivity, ammonia content, salt content, and heavy metal content. The resistivity should be greater than or equal to 0.5M Ω CM， The conductivity should be less than or equal to 2 μ S, the ammonia content should be less than or equal to 0.3 μ g/ml, the salt content should be less than or equal to 0.06 μ g/ml, and the heavy metal content should be less than or equal to 0.5 μ g/ml.
The preparation of medical device cleaning and purification water equipment, biopharmaceutical purification water equipment, and ultrapure water processes can be roughly divided into four types: medical device cleaning and biopharmaceutical purification water equipment,
1. Adopting primary reverse osmosis, ion exchanger, and purified water tank;
2. Adopting first stage reverse osmosis, pH regulation, second stage reverse osmosis, and purified water tank;
3. Adopting a first stage reverse osmosis machine, intermediate water tank, EDI system, and purified water tank to meet the different requirements of different users for high-purity water.
4. Adopting a first stage reverse osmosis machine, a second stage reverse osmosis machine, an intermediate water tank, an EDI system, and a purified water tank to meet the different requirements of different users for high-purity water.
Comparison of four processes for preparing ultrapure water for the pharmaceutical industry. The current process for preparing ultrapure water for the electronic industry is based on the above three processes, while most other process steps are derived from different combinations and combinations of the above three basic process steps. The first method is to use ion exchange resin, which has the advantages of low initial investment and less space occupation, but the disadvantage is that it requires frequent ion regeneration, consumes a lot of acid and alkali, and has certain environmental damage. The second method, which uses reverse osmosis as a pretreatment and is equipped with ion exchange equipment, is characterized by higher initial investment compared to using ion exchange resin method, but the regeneration cycle of ion equipment is relatively long, and the cost of acid-base is much lower than using ion resin method alone. But it still has certain destructive effects on the environment. The third method is to use reverse osmosis as a pretreatment and then equip it with an electrodeionization (EDI) device. This is currently an economical and environmentally friendly process for producing ultrapure water, which can continuously produce ultrapure water without the need for acid-base regeneration and has little environmental damage. But its disadvantage is that the initial investment is relatively expensive compared to the above two methods.
The characteristics of purified water equipment for medical device cleaning: The water produced by small medical device cleaning purified water equipment should comply with the new pharmacopoeia purified water standards and GMP standards. Adopting stable performance water pumps, imported reverse osmosis membranes and other high-quality components, fully automatic operating system, and efficient automatic flushing. Adopting imported instruments can accurately and continuously analyze and display water quality. Suitable for purified water for medical device cleaning, sterile purified water for medical device cleaning, etc.
