供应 FST系列双程反渗透装置
双级反渗透就是**级反渗透的透过水经调整PH值后，再由第二级高压泵送进第二级反渗透系统处理，从而获得透过水的过程：一级反渗透的系统脱盐率≥99．5％。这样就能是含盐量在1000ppm以下的原水。不经过离子交换直接处理到符合《GB7323?1998》瓶装饮用纯净水标准中的理化指标。
The principle of 2-grade hyperfiltration devicd is 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).
