RO Biocide · UN-611

Fungicide for Reverse Osmosis Film Components

Non-oxidizing biocide for RO membrane systems. Safe for polyamide membranes, controls biofilm and biofouling without degrading membrane material.

Description

UN-611 is a non-oxidizing, broad-spectrum biocide specifically engineered for polyamide composite RO membranes. Unlike chlorine and other oxidants — which destroy polyamide membrane active layers — UN-611 is fully compatible with TFC and CPA membranes. It penetrates biofilm and kills microorganisms by disrupting cell membranes, then is easily flushed out without lingering.

Typical Applications
  • RO membrane biofouling control
  • Shock and continuous dosing applications
  • Post-CIP (clean-in-place) preservation
  • Offline membrane storage
Included in Programs

This product ships as part of one of our productised Water Chemistry Programs — recurring chemistry supply, KPI accountability, and engineering support bundled under a single SLA. If you’re running a program-scale duty rather than buying SKUs ad-hoc, the program path is cheaper and more reliable.

Other chemistries in the range

Complementary products worth specifying together.

Most industrial water programmes use 3–5 chemistries in concert — a coagulant, an antiscalant, a biocide rotation, and a corrosion inhibitor. Here are three from our catalogue that pair commonly with this product.

Common questions

Procurement, dosing, and what to expect.

What is the typical lead time for Fungicide for Reverse Osmosis Film Components in Pakistan?

Stock-spec UN-611 ships from our Karachi warehouse within 3-5 working days. Custom-blend orders or larger volumes (>5 metric tonnes) take 2-3 weeks if drawn from our Innovative Water Technology line, or 4-6 weeks if direct-imported from Shaanxi Ande in China.

What's the minimum order quantity for UN-611?

For Fungicide for Reverse Osmosis Film Components, MOQ is typically 200 kg for stock-spec liquid grades and 1 metric tonne for solid/granular forms. Trial drums (25–50 kg) are available on request for new accounts running pilot tests before committing to a programme.

Do you provide technical support and a dosing programme with UN-611?

Yes. Every order includes a written dosing programme based on your feedwater analysis (LSI/S&DSI for RO, plant capacity for cooling). For ongoing supply contracts, our applications engineer visits the plant on commissioning and reviews KPIs quarterly. Emergency support via WhatsApp at +92 300 823 9990 — same engineer on the line.

How does UN-611 compare to imported alternatives?

UN-611 is produced by Shaanxi Ande Technology (China) — independent IP, international certifications, and a track record across the global power, steel, and oil sectors. Locally blended in Karachi by Innovative Water Technology when needed, which keeps pricing in PKR and lead times under a week. Quality is verified per-batch with COA; we share third-party assay on request.
