Multi leaf spiral technique

Multiple pages of the external thread can fundamentally solve the shortage of water resources, such as the shortage of existing technologies, such as short service life. External rotary technology can effectively shorten the length of the pure water flow channel, reduce the resistance of water, in the collection process, improve the flow of water, increase the yield of water. To transform the central manifold, and set up a number of internal and external support, so that the membrane tube force uniform, deformation, can effectively ease the pressure inside the membrane bag, so that the use of membrane components more stable, to extend the service life of the membrane element.
