Non oxidizing fungicide FRA2100

FRA2100 Membrane System Non-Oxidizing Biocide is a high-performance, broad-spectrum, environmentally friendly microbial control agent designed specifically for reverse osmosis systems. Its molecular structure rapidly penetrates microbial cell membranes, disrupting key metabolic processes and destroying cellular structures. It effectively eliminates and inhibits common microbial contaminants such as bacteria, fungi, and algae. With excellent biofilm removal properties, FRA2100 is non-foaming, low-toxicity, and fully miscible with water. It is compatible with all major membrane materials and causes no membrane damage. Widely applicated for microbial control for RO systems, as well as in industries such as papermaking, industrial cooling water, metalworking fluids, and more, FRA2100 offers a safe, efficient, and versatile water treatment solution with excellent compatibility and biodegradability.

Product Features

• Broad-Spectrum Efficacy: Provides powerful control against bacteria, fungi, and algae, especially effective against Gram-negative bacteria and Pseudomonas species.
• Superior Biofilm Removal: Efficiently removes biofilms and microbial slimes, restoring system flow and heat transfer efficiency.
• Excellent Water Solubility & Compatibility: Fully miscible with water and compatible with various formulations, unaffected by proteins, surfactants, or other common additives.
• Safe & Eco-Friendly: Low toxicity, non-foaming, and readily biodegradable, minimizing environmental impact.
• Universal Membrane Compatibility: Compatible with all major reverse osmosis membrane types (e.g., Dow, Hydranautics, Toray), with no risk of membrane degradation.
• Multi-Industry Application: Suitable not only for RO systems but also for papermaking, cooling water systems, metalworking fluids, coatings, wood preservation, and other industrial microbial control applications.

Note: FRA2100 is functionally equivalent to Solvay’s ACTICIDELA and Thor Chem’s THOR1209.

Instructions for Use

FRA2100 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 50–300 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 300–600 ppm FRA2100 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

6 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.
• FRA2100 is mildly corrosive. Wear appropriate PPE; rinse immediately with plenty of water upon skin or eye contact.
