摘要

对存在和不存在的软化系统作为水的预处理，通过反渗透膜进入分离过程进行了比较。对反渗透的以下参数进行了评价:进水pH值;流动的渗透;第一级和第二级膜内进水压力;以及废品的压力，在没有和有软化系统的情况下。结果表明，在反渗透过程中加入软化系统作为预处理，防止了二氧化硅的过早沉积，从而增加了膜的使用寿命

STUDY OF PRODUCTION OF REVERSE OSMOSIS DEMINERALIZED WATER FOR BOILERS

A comparison of the presence and absence of a softening system as a pretreatment of the water that is fed into the separation process by reverse osmosis membranes was performed. The following parameters of the reverse osmosis were evaluated: the pH of the feed water; the flow of the permeate; the pressure of the feed water in the membrane in the first and second stages; and the pressure of the reject, both in the absence and the presence of the softening system. The results indicated that the inclusion of a softening system as a pretreatment for feeding the reverse osmosis process prevented the premature deposition of silica, thereby increasing the useful life of the membranes
