Product FAQ

Typical dosing is 3–5 ppm based on feedwater flow, adjusted after a scaling-index review. For high-hardness Gulf feedwater we usually start at 4 ppm and confirm with a 30-day membrane inspection. Our technical team will size it for your specific plant free of charge.

Yes. The product is NSF/ANSI 60 compatible at the recommended dose rates and is used on several municipal desalination lines in Oman. Certificates are supplied with each batch.

Yes — it is formulated to protect mixed-metallurgy systems including mild steel, copper alloys and galvanised surfaces. Keep the treated-water pH between 7.5 and 9.0 and maintain the reserve as shown on the dosing chart to avoid white rust on fresh galvanising.

For light carbonate scale, circulate for 2–4 hours at 45–55 °C and monitor free acid every 30 minutes. Stop once the acid strength stabilises (scale fully dissolved). Always passivate and neutralise the exchanger afterwards before returning it to service.

Use the diluted solution (1:10 to 1:20) and do not leave it in prolonged contact with bare aluminium. At working dilution and a normal 5–10 minute dwell it is safe; neat product on unprotected aluminium can cause etching.

Replace reagents 12 months after opening, or by the printed expiry date, whichever is sooner. Store them out of direct sunlight below 30 °C. Replacement reagent packs for kit 311 are stocked locally for next-day delivery.

Shelf life is 24 months in sealed original drums kept between 5 °C and 40 °C, away from direct sun. Stir or roll drums that have stood for more than three months before dosing.
