Specialized pure water equipment for operating room cleaning-Fornitore globale

3F, Building A6, Building 4, Factory 4, Plot 4, Industrial Concentration Development Zone West, Qingyang District, Chengdu City

Suitable for operating room cleaning water, as the operating room must achieve sterility, the water quality requirements for operating room cleaning pure water are relatively stricter and higher. It is often required that the resistance value of ultrapure water should be above 2M Ω. To ensure the safety of ultra pure water used in medicine, the entire system of the operating room cleaning pure water equipment is made of all stainless steel materials, and a sterilization device must be installed before the water point.

The water quality meets the GMP standard of the 2010 edition of the pharmacopoeia; Electrical resistivity ≥ 2M Ω .cm@25 ℃ (or conductivity ≤ 0.5 μ s)/ cm@25 ℃), ammonia ≤ 0.3 μ g/ml, salt ≤ 0.06 μ g/ml, heavy metals ≤ 0.5 μ g/ml.

Classification of Operating Room Pure Water Process:

1. Raw water → Raw water booster pump → Multi medium filter → Activated carbon filter → Softener → Precision filter → Primary reverse osmosis equipment → Intermediate water tank → Intermediate water pump → Ion exchanger → Purified water tank → Pure water pump → UV sterilizer → Micro porous filter → Water point

2. Raw water → Raw water booster pump → Multi medium filter → Activated carbon filter → Softener → Precision filter → First stage reverse osmosis → PH adjustment → Intermediate water tank → Second stage reverse osmosis (with positive charge on the surface of the reverse osmosis membrane) → Purified water tank → Pure water pump → Ion exchange column → UV sterilizer → Microporous filter → Water point

3. Raw water → Raw water booster pump → Multi medium filter → Activated carbon filter → Softener → Precision filter → Primary reverse osmosis machine → Intermediate water tank → Intermediate water pump → EDI system → Purified water tank → Pure water pump → UV sterilizer → Micro porous filter → Water point

Comparison of Pure Water Processes in Operating Rooms:

The process of cleaning pure water equipment in the operating room is basically based on the above three types, and most of the other process flows are derived from different combinations and combinations of the above three basic process flows. Their advantages and disadvantages are listed below:

1. The first method of using ion exchange resin has the advantages of low initial investment and less space occupation, but the disadvantage is that it requires frequent ion regeneration, consumes a large amount of acid and alkali, and has certain environmental damage.

2. The second method uses two-stage reverse osmosis as a pretreatment and is equipped with ion exchange equipment. Its characteristic is that the initial investment is higher than using ion exchange resin, but the regeneration cycle of the ion equipment is relatively long, and the consumption of acid and alkali is much less than using ion resin alone. But it still has a certain degree of destructive impact on the environment.

3. The third method uses two-stage reverse osmosis for pretreatment and is equipped with an electro deionization (EDI) device, which is currently the most economical and environmentally friendly process for producing ultrapure water. It does not require regeneration with acid or alkali and can continuously produce ultrapure water without causing much damage to the environment. Its disadvantage is that the initial investment is relatively expensive compared to the above two methods.
