Multi Mode Dosing RO Biocide Protecmbc1560 for Desalination Membrane Protection

Oxidizing biocides use chemical oxidation to kill microbes, providing rapid, broad-spectrum control. Non-oxidizing biocides disrupt microbial metabolism without oxidation, offering longer residual protection and better compatibility with polyamide membranes. Oxidizing biocides may require neutralization with a reducing agent before contact with polyamide membranes.

Selection depends on: Membrane type: Polyamide membranes require non-oxidizing biocides or properly neutralized oxidizing biocides Water quality: High organic content may require shock treatment with oxidizing biocides System design: Continuous dosing systems often use non-oxidizing biocides for residual protection Regulatory requirements: Local discharge regulations may influence selection Contact our technical team for a free water analysis and customized recommendation.

Typical dosage ranges: Non-oxidizing biocides: 50-200 ppm for shock treatment; 1-5 ppm for continuous dosing Oxidizing biocides: 1-5 ppm for pre-treatment (must be neutralized to <0.1 ppm residual before membrane contact) Application methods include: Continuous injection into feed water Shock treatment (batch dosing) for severe contamination Membrane preservation during system shutdown Always follow the product-specific technical datasheet for precise dosing guidelines

Yes, ProtecMBC series biocides are generally compatible with most RO antiscalants, coagulants, and flocculants. However, we recommend: Avoid mixing oxidizing and non-oxidizing biocides directly Maintain proper contact time between chemical additions Conduct compatibility testing when using new chemical combinations

Key monitoring parameters: Microbial counts: Regular ATP or plate count testing of feed Transmembrane pressure (TMP): Stable TMP indicates effective biofouling control Biocide residual: Use appropriate test kits to ensure target residual levels Membrane performance: Maintain consistent flux and salt rejection rates
