Nothing affects RO performance more than feed water quality. Proper pretreatment protects membranes from chlorine damage, scaling, biofouling, and particulate fouling.

Pretreatment
5-Micron Sediment Pre-Filter
Removes sand, silt, rust, and particulates from feed water before RO membranes. Essential for any water with turbidity. Extends membrane life significantly.

Pretreatment
GAC Carbon Pre-Filter
Removes chlorine and chloramines from feed water before RO membranes — chlorine degrades TFC membranes rapidly. Coconut-shell or coal-based GAC available.

Pretreatment
Carbon Block Pre-Filter
High-contact-time carbon block removes chlorine, VOCs, and organics that GAC may not capture fully. Better for heavy chlorination or chloramine treatment.

Water Softener Pre-Treatment
Ion exchange softening removes calcium and magnesium before RO membranes. Prevents carbonate and sulfate scaling. Required for hard water above 15 GPG.

Ultrafiltration (UF) Pre-Filter
0.01-micron hollow fiber UF membrane removes bacteria, viruses, colloidal particles, and high-SDI content before RO stage. Recommended for surface water sources.

Membrane Cleaning Solution
Acid and alkaline cleaning solutions for RO membrane restoration. Removes carbonate scale, biofilm, iron fouling, and organic deposits. Extends membrane life.
