How to resolve the "core" of purified water equipment?

[Pharmaceuticals.
com technical article] Purified water equipment can meet the high-quality water requirements of pharmaceutical factories and hospitals for the production of purified water and the preparation of large infusions, and is widely used in medicine, biochemistry, chemicals, hospitals and other industries
.

In recent years, China's pharmaceutical industry has developed rapidly.
Some data predict that by the end of 2020, the market size of China's pharmaceutical industry will reach 1.
79 trillion yuan, which also brings opportunities to the purified water equipment industry
.

At the same time, with the increasingly strict supervision of the pharmaceutical industry, pharmaceutical companies have also put forward higher requirements for the water quality of purified water equipment
.

The filter element is the heart of the purified water equipment and plays a decisive role in the effluent quality, so it is necessary to effectively protect the filter element at all levels
.

It is understood that a purified water equipment is usually composed of PP cotton, activated carbon, RO membrane and other filter elements
.

The filter elements at all levels have different functions, such as the first-level pretreatment, which can remove large particulate matter, residual chlorine, calcium ions, and magnesium ions in the water to achieve a better pretreatment effect; the second-level reverse osmosis can filter out most of the inorganic ions.
Contaminants included; tertiary ion exchange to remove ionic species
.

 　　The "core" of the purified water equipment can be resolved in time to ensure the quality of the produced water
.

On the one hand, correct installation is required, otherwise the stable operation of pharmaceutical purified water equipment may not be guaranteed, resulting in water pollution
.

Before installation, it is necessary to pay attention to whether the installation site is flat, whether the environment is clean, and whether the installation location is safe; during the installation process, all pipes, valves, instruments, and large parts should be assembled according to specifications and standards, and relevant signs should be pasted.

.

 　　On the other hand, the filter element has been used for a long time and absorbed a lot of impurities, which may cause blockage and greatly weaken the ability to purify water.
Therefore, it is necessary to replace the filter element regularly to avoid secondary pollution to the water
.

 　　The author learned that due to the high cost of the filter element, many users will think about taking the filter element out and cleaning it, and then putting it back
.

So is this approach scientific? In this regard, some technical personnel pointed out that this approach is not desirable
.

The reason is that the structure of the filter element is complex, and the filter element will change color after absorbing too much impurities
.

Therefore, in order to purify the water of the pure water equipment, it is necessary to replace the filter element regularly
.

 　　So, how often does the filter element of the pure water equipment need to be replaced? The technician said that the replacement time period is also different depending on the filter element
.

Under normal circumstances, the replacement cycle of ultrafiltration material filter element is 12-24 months, the replacement cycle of activated carbon filter element is 6-18 months, and the replacement cycle of reverse osmosis membrane filter element is 18-36 months
.

 　　In addition to the need to pay attention to the protection of the filter element, the quality of the filter element is also critical, which also reminds manufacturers to consider not only the price factor, but also the product quality when choosing a filter element, so as to avoid hidden dangers to subsequent production and economic losses.

.

 　　At present, improving purified water quality and water production efficiency can be said to be the pursuit of major pharmaceutical companies
.

In this regard, some purified water equipment manufacturers are also constantly strengthening research, introducing new technologies and new processes, and improving and upgrading purified water equipment
.

For example, the purified water equipment built by some enterprises adopts new technologies such as single-stage or double-stage reverse osmosis, EDI, etc.
as its core technology.
requirements for the production of purified water or distilled water for laboratory diagnostic reagents
.

According to another introduction, the entire system of this product is made of SUS304L or SUS316L all-stainless steel material, and must be equipped with ultraviolet and ozone sterilization devices before the water point, and pasteurization can also be used
