What affects the deterioration of the water quality of the ultra-pure water machine?

Most of the Water Tanks used by ultrapure water machines on the market are pressure barrels or industrial Water Tanks. Many users of ultrapure water machines will find that the water quality cannot meet the initial standard after long-term use of the water machine . Bacteria, heat sources or TOC have exceeded the water quality standard stated by the water machine, and one of the reasons for this is that the water machine uses pressure barrels or industrial Water Tanks as water storage equipment!

This is the unspoken rule of the ultrapure water industry today, one of the rules that everyone obeys by default, but why is this?

Because pressure barrels and industrial Water Tanks are cheap, low-cost, and easy to operate, manufacturers of ultra-pure water machines can use them directly, but the consequences are paid by users.

pressure tank

First of all, let us understand the principle of the pressure tank, so that you can know how "ultra-pure" the water produced by the ultra-pure water machine you are using now is!

The pressure tank includes an upper cover, a lower cover and an inflatable diaphragm. The upper cover is provided with a water inlet, and the lower cover is provided with an inflatable valve. pressure. By using it in conjunction with a high voltage switch, it will operate actively.

However, due to the sealed nature of the pressure tank, it gives the impression that it has the characteristics of protecting the water quality from being polluted. However, when using the pressure tank to store water, some water will not be transported by the pressure tank to form stagnant water because of the pressure. The flowing stagnant water will breed bacteria and form a biofilm on the inflatable diaphragm, and the sealed pressure tank cannot be cleaned, which will only make the pressure tank a hotbed of water quality deterioration in the end!

Industrial Water Tank

Industrial Water Tanks are made of cheap industrial plastic buckets, which have poor airtightness and are prone to secondary pollution to the water quality. Separated, it is easy to form a safety hazard, and the groundwater pipeline connected to the overflow will also make the water quality unable to be guaranteed.

The ultrapure water machines sold on the market today basically use these two types of Water Tanks as water storage devices, but the disadvantages of these two types of Water Tanks are obvious.
