The role of the pressure tank of the ultrapure water machine and what problems should be noticed in the use of RO membrane

Author: Source: Time: 2019-12-05 Category: Technical Articles

With the development of the times, the sewage in laboratories in industry and industry is constantly increasing. In addition to purchasing laboratory sewage treatment equipment , many will also use ultra-pure water machines to treat some sewage. Today I will take everyone to understand Related knowledge of the ultra pure water machine:

Ultra pure water machine pressure bucket:

The ultrapure water mechanism uses pure water, stores it in a pressure tank, and then removes it from the pressure tank. We all know that the water of ultrapure water machine is very small and cannot meet the user's requirements for water. Then, the pressure bucket can come in handy: when the user has no water, or water, the pure water produced by the ultra-pure water machine is stored in the pressure tank. When the user needs water directly from the pressure bucket, the user does not need to spend time waiting for the system water. You can use pure water at any time.

The principle of the pressure bucket is to use the inside of the balloon to expand the air, squeeze the air into the water, so that the water is in the opposite direction under pressure. When the pressure is equal to water, WI.

I will not fill the pressure bucket to continue, and then reach pressure equilibrium. When the faucet is opened, the internal pressure of the pressure bucket is greater than the external pressure, and pure water flows out until the outlet pressure equals atmospheric pressure, and then stops flowing. It can be said that the pressure bucket is an essential part, which greatly facilitates the manufacture of pure water.

The pressure tank can not only prevent secondary pollution caused by sunlight and microorganisms, but also allow the experimenter to use it with purified water, which greatly facilitates the experimenter. At the same time, the designed pressure barrel material will not cause secondary pollution of water, and it is safe and reliable. LTECH ultra-pure water machine fully enclosed vacuum aseptic storage tank can effectively guarantee water quality and water safety.

The process of using ultrapure water machines for pressure buckets plays a very important role. In the purchase of ultrapure water machines, we cannot ignore the pressure buckets. Pressure buckets must be keen to purchase and choose carefully. On the one hand, it guarantees the quality of pure water, and on the other hand, it ensures that no explosion accidents occur when using pressure buckets, and to ensure personnel safety.

What should be paid attention to when using RO membrane:

Ultra pure water machine and pure water machine have become one of the indispensable equipment for life, production, experiment and scientific research. Pure water pure water machine and ultra pure water machine use RO reverse osmosis principle. Reverse osmosis membrane has become one of its main components, which is directly related to the use and performance of the equipment. This article only takes laboratory ultrapure water machine as an example.

The source water is usually tap water or groundwater, and individual places are pure water or mineral water. The source water contains impurities such as organics, inorganic ions, solid particles, and bacteria. In the water purification process, impurities in the water are removed. The reverse osmosis membrane in the ultrapure water machine can theoretically remove various impurities in water, so that the reverse osmosis membrane is blocked and damaged. When the reverse osmosis membrane is abnormal, the water quality of purified water or ultrapure water will decline, and the water quality will not reach the water quality standard. Unqualified pure or ultrapure water can seriously affect the experiment. The maintenance of RO membrane is roughly divided into routine maintenance and troubleshooting.

Routine maintenance refers to the normal operation of the equipment in daily operation, and the water quality does not change much. In three aspects, the RO membrane will accumulate certain impurities in daily use, and will not be cleaned for a long time, which will block the RO membrane and even cause the RO membrane to fail. Therefore, RO membranes are often cleaned in daily use. In the purchase process of ultra-pure water machine, the use of ultra-pure water machine with automatic cleaning function can avoid unnecessary trouble caused by the reverse osmosis membrane cleaning process.

The ultrapure water machine is in a sealed state and has no automatic cleaning function. After cleaning the RO membrane, the water quality of pure water or ultrapure water will be reduced. The cleaning cycle of the reverse osmosis membrane depends on its own conditions. No ultra-pure water machine maintenance for a long time. Every year during the Spring Festival holiday, part of the National Day, due to climatic conditions, the climate does not use ultrapure water machines for a long time to ensure that there is no shortage of water in the interior, the ultrapure water machine can ensure that the bucket is closed before it is filled with water. If conditions permit, you can turn on the water once a week and drain the water from the machine to prevent the heat from freezing.

The working temperature of the ultrapure water machine should not be too high or too low. If the temperature is too high, the diameter of the reverse osmosis pores will increase, the particles will increase, the purification effect will decrease, and the water quality of ultrapure water or pure water will obviously decrease. Ultra-low temperature water is also not conducive to ultra-pure water machines. It is recommended to keep the working temperature of the ultrapure water machine between 15 and 30. 25 degrees is the best temperature.
