This water purified machine used in drink water.easy to operate.  hollow ultra-filter device:

working principle :The ultra-filter technique is a type of film separating method which use the pressure as the thrust and make use of the permeance( semi-permeance) film. When the pressure of the system larger than the certain value, the water molecule, medium and other small molecule will through the film and flow out from one terminal through the water path and the general pipeline. The others including the large molecule, bacillus and the virus will be blocked at the inlet and will flow out from the thick water outlet. By this, the water will be purified . the ultra-filter differs from the signal screen separating process which can condense
