1, the expansion of the sealing ring in the reverse osmosis device in order to achieve the sealing isolation of each section of the membrane shell, reverse osmosis device, water treatment device needs three kinds of sealing ring, in order to reduce the installation resistance, the system should be installed on each sealing ring surface coated with water or glycerin. Particular attention should be paid to the use of Vaseline or other oil grease lubricants, which would otherwise cause the cracking of freshwater pipelines, especially the sealing ring.
The expansion of the apron generally does not directly affect the operating effect of the system, but will affect the reloading of the system after unloading, that is, the expansion apron in the loading process is difficult to enter the groove.
Water treatment Equipment
2. Basic requirements for effluent quality of purified water equipment Pure water prepared with pure water equipment is used in medicine, biomedicine and other industries. But what are the basic criteria for the quality of pure water? " Both the Chinese pharmacopoeia and the European Pharmacopoeia specify that the raw water for pharmaceutical water must meet at least the drinking water standard.
If the criteria are not met, evolutionary processing is performed until the standard is met. With the exception of Escherichia coli, other bacteria must not exceed 100/ml at the same time. In the process of making water from pure water equipment, internal pollution will also be produced, and all kinds of water treatment equipment in pure water purification equipment may become pollution sources. Therefore, it is necessary to clean and disinfect pure water purification equipment on a regular basis.
In addition, the end of the pure water purification equipment should also be installed sterilization and disinfection device. 3, chemical water equipment water quality characteristics of purifying water equipment effluent quality in line with the health standards set by the state and the actual production standards of enterprises. The effluent from pure water purification equipment & pure water has two characteristics. One feature is the gradual increase in the number of disinfection and sterilization equipment installed on pure water purification equipment. Another feature is that the pipeline distribution system of pure water purification equipment replaces the traditional water supply pipeline with circulating pipe, which is not only to control microbial pollution, but also to control the increase of bacterial endotoxin.
At the same time, attention should be paid to the effect of tube flow rate on microbial reproduction, that is, the pipeline flow rate is too low or clogged, may lead to increased microbial reproduction, affecting water quality. Selection of installation location of softening water equipment The main point of softening water equipment effluent quality is good, the system runs stably, has been used by many enterprises.
When installing softened water equipment, you should pay attention to a few points:
1, softening water equipment should be as close as possible to drainage.
2. If additional water treatment equipment is required, the installation location should be retained. 3, because salt is regularly added to the salt box, so the location of salt should be set.
Softening water equipment to reduce the hardness of water equipment, mainly in addition to removing calcium, magnesium ions in the water, softening water equipment in the process of softening water, can not reduce the total salt content in the water, could be used for air conditioning and other systems of recharge water softening and domestic water treatment.
4, do not install softening water equipment within 3 meters of the boiler, otherwise hot water will return to the softening water equipment, resulting in damage.
5, the softening water equipment placed at room temperature below 1C and higher than 49 ℃. Softening water equipment is a water treatment equipment that removes Ca, Mg plasma, reduces the hardness of water and softens water. After long-term use of softened water equipment, certain precautions should be followed.
