Menm jan solisyon asid yo pa bon pou manbràn, solisyon mordan se menm domaje anpil manbràn eleman. pouvwa Asid piki dwe enkòpore nan sistèm lan PRETREATMENT RO kontwole pH epi minimize chans pou tandans nan echèl-fòme nan dlo a manje. se Asid piki endike si echèl fòme tandans nan nan kouran an sèl pi wo pase +0.3 lè yo mezire LSI la. ka swa silfirik oswa asid HYDROCHLORIC gen pou itilize pou objektif sa a.

Just as acidic solutions aren't good for membranes, caustic solutions are equally damaging to membrane elements. Acid injection may be incorporated into the RO pretreatment system to control pH and minimize the scale-forming tendency of the feed water. Acid injection is indicated if the scale forming tendency of the brine stream is above +0.3 as measured by the LSI. Either sulfuric or hydrochloric acid can be used for this purpose.
