Novel antiscalant dosing control

Using the automatic control, the antiscalant dose was within 4-0.5 ppm of the target dose at all times (Fig. 6). The results show that the extremes of under- dosing and overdosing were removed, which means that the RO membranes were more effectively protected against scaling and fouling. The long-term results of this trial were: Operating …

In general, the antiscalant dose recommended by the antiscalant suppliers lies in the range between 2 to 5 mg/L in the feed water [21]. In this study, antiscalant doses of 2 mg/L and 5 mg/L in the feed water were tested which corresponded to 13.3 mg/L and 33.3 mg/L in the synthetic concentrate of 85% recovery, respectively.

RO Antiscalant Dosing Calculation

DEFINITION. Antiscalant chemicals are utilized as pretreatment when injected into untreated water before it is sent to reverse osmosis systems. Antiscalant is important in helping the membranes used in the RO system from being exposed to scale forming (causing fouling) by delaying the reaction of magnesium, bicarbonate, and calcium.
