Description
HC 90 Antiscalant for RO Systems – High iron content
Product Features: HC 90 is a high-performance liquid antiscalant and dispersant designed to prevent scaling caused by carbonates, sulfates, and iron oxides in membrane systems. It is suitable for various water sources and especially effective for feedwater with high iron content.The formula combines a powerful iron dispersant with polymers to prevent hardness and iron fouling, helping to extend cleaning intervals, prolong membrane life, and reduce operating costs. Widely used in RO systems.
Note: High iron in feedwater may lead to membrane fouling over time. HC 90 is designed to mitigate this issue.
Usage Instructions:
-
Dosing Point: Add before the security filter for best results.
-
Dosage: Refer to software calculation based on feedwater salinity, temperature, and recovery rate. Adjust as needed.
-
Dilution: Can be dosed directly or diluted with RO permeate or demineralized water. Do not exceed 10× dilution.
Key Advantages:
-
Effectively controls scaling from CaCO₃, CaSO₄, BaSO₄, and SrSO₄. No scaling even at LSI up to 3.0.
-
Excellent dispersing power to remove particulate fouling on membranes.
-
Suitable for all major membrane types.
-
Effective within pH range 5–9.
-
Compatible with aluminum and iron oxides in feedwater.
-
Easy to dose directly or after dilution.
-
Liquid form; easy to handle and mix.
