Non oxidizing fungicide FRA2000
FRA2000 is a high-performance non-oxidizing biocide specifically applicated for reverse osmosis membrane systems. Leveraging targeted molecular technology, it effectively combats biofouling by penetrating microbial cell structures and neutralizing bacteria, fungi, and algae. This action significantly suppresses biofilm formation, ensuring stable membrane flux and permeate quality. With exceptional membrane compatibility and eco-friendly properties, FRA2000 is widely deployed across power generation, chemical processing, electronic ultrapure water, food & beverage, and municipal water sectors—delivering a safe, sustainable microbial control solution that supports long-term system reliability and operational cost efficiency.

Instructions for Use
FRA2000 supports three scientifically validated application modes:
- Continuous Low-Dose Dosing (Daily Operation):
- Continuously inject into RO feed water at 1–5 ppm during normal operation to suppress microbial growth. Ideal for systems with moderate biofouling risk; dosage adjusted per feedwater quality and monitoring data.
- Intermittent Shock Dosing (Preventive Maintenance):
- Inject at 50–400 ppm for 30–60 minutes, typically once every 1–2 weeks. Controls biofilm formation without interrupting production.
- Shutdown Cleaning (System Restoration):
For severe biofouling or scheduled maintenance:
- Prepare solution at 400–800 ppm FRA2000 concentration.
- Adjust pH to 4–6 (using citric acid) to protect membranes.
- Recirculate for 45–60 minutes.
Note: Perform standard chemical cleaning first if heavy organic/inorganic fouling is present.
Packing and Storage
Packaged in 25 kg plastic drums. Store in a cool, dark place at room temperature.
Shelf Life
10 months.
Precautions
- Do not use if feedwater contains residual oxidants (e.g., chlorine, hydrogen peroxide), hydrogen sulfide, or high levels of soluble iron/manganese ions.
- FRA2000 is mildly corrosive. Wear appropriate PPE; rinse immediately with plenty of water upon skin or eye contact.
