How to solve the filter element problem of purified water equipment?

 

The purified water equipment can meet the high quality water requirements of pharmaceutical factories and hospitals, such as purified water preparation, large infusion preparation and so on. It is widely used in medicine, biochemistry, chemical industry, hospital and other industries. In recent years, China's pharmaceutical industry has developed rapidly. Some data predict that by the end of 2020, the market scale 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 enterprises also put forward higher requirements for the water quality of purified water equipment.

 

Filter element is the heart of water purification equipment, which plays a decisive role in the quality of effluent, so it is necessary to effectively protect all levels of filter elements. It is understood that a purified water equipment is usually composed of PPC, activated carbon, RO membrane and other filter elements. All levels of filter elements have different functions. For example, the first level of pretreatment can remove large particles, residual chlorine, calcium ions and magnesium ions in water to achieve better pretreatment effect; the second level of reverse osmosis can filter most pollutants including inorganic ions; the third level of ion exchange can remove ionic substances.

In order to ensure the quality of produced water, the filter element problem of purified water equipment should be solved in time. On the one hand, it needs to be installed correctly, otherwise it may not be able to ensure the stable operation of pharmaceutical purified water equipment, causing 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 position is safe; during installation, all pipelines, valves, instruments and large parts shall be assembled according to the specifications and standards, and relevant signs shall be pasted.

 

On the other hand, if the filter element is used for a long time, it will absorb a lot of impurities, which may cause blockage and greatly weaken the ability of purifying water quality. Therefore, it is necessary to replace the filter element regularly to avoid secondary pollution to water.

The author learned that due to the high cost and price of the filter element, many users will want to take out the filter element and clean it, and then install it back. So is this scientific?

 

In this regard, some technicians pointed out that this approach is not desirable. The reason is that the structure of the filter element is complex. After absorbing too many impurities, the filter element will change color. Simple flushing can not remove the residual impurities in the filter element, and can not guarantee the filtering effect. Therefore, in order to improve the water purification capacity of purified water equipment, it is necessary to replace the filter element regularly.

So, how often does the filter element of purified water equipment need to be replaced? The technician said that according to the different filter element, the replacement time cycle is not the same. Under normal circumstances, the replacement cycle of ultrafiltration material filter element is 12-24 months, that of activated carbon filter element is 6-18 months, and that 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 very critical, which also reminds manufacturers to consider not only the price factor, but also the product quality when choosing the filter element, so as to avoid bringing hidden dangers to subsequent production and causing economic losses.
