Most antiscalant recommendations look at feedwater. Liberta calculates the concentrate side.
Product selection depends on feedwater quality, recovery, membrane type, concentrate chemistry, SDI/turbidity, pH, temperature, pretreatment performance and cleaning history.
Analysis First
Water analysis before product recommendation.
TDS, SDS and certificates are shared upon request.
RO and NF membrane problems often become visible as pressure increase, flux reduction, salt passage change, cleaning frequency or premature membrane stress. The root cause may be scaling, colloidal fouling, organic fouling, biofouling, pretreatment carryover or unsuitable chemical selection. Liberta separates feedwater data from concentrate-side risk. The decision is not only what enters the membrane system; it is what happens after recovery concentrates the salts and fouling load on the membrane surface. This page should route the visitor to PureGuard® antiscalants, PureGuard® membrane cleaners, BlancoWT® pretreatment support where applicable and RO-Watel for product and dosage selection.
Typical water-related problems
| Problem | Why It Matters | Response |
|---|---|---|
| Carbonate / sulfate scaling | CaCO3, CaSO4, BaSO4 and SrSO4 risks increase on the concentrate side. | |
| Silica fouling and scaling | Silica risk depends on concentration, pH, temperature and antiscalant route. | |
| Colloidal and SDI load | Turbidity, colloids, metal hydroxides and pretreatment carryover can foul membranes. | |
| Organic and biological fouling | Organics, biofilm tendency and upstream instability can increase pressure and cleaning demand. | |
| Cleaning frequency | Wrong chemistry may increase CIP need, reduce permeate and raise operating pressure. |
