Principle of ultrafiltration membrane filtration Hollow fiber ultrafiltration membrane is an important branch of membrane separation technology. It is characterized by separation at room temperature and low pressure. It has the advantages of low energy consumption, high filtration precision, large ...

1. The tools required for replacing quartz sand and activated carbon in water treatment equipment include pipe clamp, sand suction pipe and raw tape. 2. Before replacing quartz sand and activated carbon for water treatment equipment, the equipment shall be thoroughly inspected to see whether the cu...

Due to its advanced technical and economic characteristics, reverse osmosis system has formed a huge user group in various industries in China. As a deep filtration means, the surface of reverse osmosis membrane element will inevitably remain colloids, microorganisms, impurity particles and insolub...

1. Problems existing in the application of reverse osmosis equipment Compared with other desalination devices, such as evaporator, electrodialysis and double bed, reverse osmosis desalination has unique characteristics and advantages, and the localization of reverse osmosis has been paid more and m...

Technical points of using new RO reverse osmosis membrane: 1. First, wash the quartz sand and coconut shell activated carbon, and wash the newly installed quartz sand and coconut shell activated carbon for a long time. 2. Check whether there is residual chlorine. If the residual chlorine exceeds t...

Reasonable selection of water treatment equipment is the knowledge that every designer needs to master. As the core equipment of transportation and lifting, pumps are everywhere in water treatment projects. Therefore, how to select the pump is also very important! Usually, when selecting the type of...

We all know that the filtration accuracy of RO membrane is 0.1nm (i.e. 0.0001) μ m) It can filter out bacteria, heavy metals and plasma in water. Then the problem comes. Benzene molecules can be killed at about 0.5nm and Ca + ions can be killed at about 0.3nm. We can fully understand it. But w...
