The principle of 2-grade hyperfiltration devicd is used to adjust the PH-value of water through first grade device, then let second grade high pressure pump delivery liquid into the second grade hyperfil system to treat, and get the cleaned water at lawt. The desalt ratio of the 1-trade hyperfittration system is over 99.5%. It needn't flow through the way of direct exchange treatment and it can be up to the standards of bottled drinking water(GB1723-1998).
