20/06/2028 18:25

Choosing the right antiscalant chemical is very important for the long life and efficiency of your RO membrane. Poor quality or duplicate antiscalant can damage the membrane and increase costs. Here’s how you can check the quality:


---

✅ 1. Appearance & Clarity:

A good quality antiscalant chemical is clear and transparent without any particles, cloudiness, or sediment. Any haziness or suspended matter indicates impurity.


---

✅ 2. pH Value:

High-quality antiscalant chemicals have a stable pH range (usually between 5 to 7). If the pH is outside this range, the product may not perform effectively.


---

✅ 3. Density Test:

A standard density should match the supplier's specification (usually around 1.1–1.2 g/cm³). Significant deviation may indicate dilution or adulteration.


---

✅ 4. Certificate of Analysis (COA):

Always ask the supplier for a COA. This document shows the chemical composition, purity, and other important test results.


---

✅ 5. Compatibility Check:

Good antiscalants are compatible with polyamide RO membranes (used in most plants). Verify this with the supplier or technical sheet.


---

✅ 6. Performance Record:

A reliable supplier like Candour Water Solution offers tested and trusted antiscalant chemicals used successfully in multiple RO plants across industries.
