Description

An integrated water treatment system

technical field

The utility model relates to a water treatment system, in particular to an integrated water treatment system.

Background technique

With the improvement of medical technology, advanced and sophisticated medical devices are becoming more and more common in hospitals, so the cleaning requirements for medical devices are also getting higher and higher.

The cleanliness of medical equipment and utensils is very high, so there are certain requirements for the water quality of cleaning equipment and utensils. Since soft water, pure water, and ultrapure water each have different cleaning effects and water consumption on medical devices or appliances, there are currently two types of cleaning processes for medical devices and appliances:

The first one is to clean and disinfect the residues of the instruments with tap water containing disinfectant chemical reagents, then sterilize them, and then rinse the instruments with sterile pure water. For precision instruments and utensils, use ultrapure water After a final rinse, the instruments are sent to a high-temperature oven for drying. Because the tap water cleans the instruments and utensils, and then dries them at high temperature, scale spots will be left on the instruments. They often return to re-clean because they fail to meet the cleaning requirements of the instruments, which will waste a lot of water resources and electric energy.

The second method is to first clean and disinfect the residues of the instruments with pure water containing disinfection chemicals, then perform sterilization treatment, then rinse the instruments with pure water or ultrapure water, and finally send the instruments to a high-temperature oven for drying Dry processing, instruments free of traces of limescale. Due to the extremely low content of metal cations in pure water, the ability to clean residues on instruments is very poor. In order to make the cleaning meet the requirements, a large amount of pure water is used, which requires high processing capacity of the water treatment system. High energy consumption, large consumption of pure water.
