Membrane Biocides in Singapore for Non-Oxidizing RO Biofouling Control (NEWater, Pharma & Marine RO)
Innova Corporate (India) supplies non-oxidizing Membrane Biocides in Singapore for NEWater RO post-treatment, pharmaceutical water systems in Tuas and Woodlands, marine vessel RO units in Singapore shipyards, and Jurong Island petrochemical cooling towers. Biofouling is one of the most persistent problems in Singapore RO systems — bacteria, fungi, algae and sulfate-reducing bacteria (SRB) form biofilm layers on membrane surfaces that reduce permeate flow, raise differential pressure and increase energy cost. Chlorine-based biocides cannot be used directly on polyamide membranes because they cause irreversible oxidation damage. Our non-oxidizing biocides control microbial growth without attacking membrane surfaces, making them the preferred choice for Singapore NEWater, pharmaceutical and marine plants.
Our biocide range is designed for continuous feed dosing or intermittent CIP sanitisation of RO, NF and UF membranes used across Singapore. It is highly effective against a broad spectrum of microorganisms — bacteria, fungi, algae, viruses and SRB — at low dosage, reducing chemical consumption cost for Singapore plants. The liquid formulation is easy to dose with standard metering pumps and is compatible with all major membrane brands. For NEWater and pharmaceutical water systems, food-grade formulations are available that comply with PUB water quality guidelines and HSA/PIC-S requirements.
Key Features & Strategic Benefits for Singapore NEWater, Pharma & Marine RO:
- Broad-Spectrum Microbial Control: Rapidly eliminates bacteria, fungi, algae, viruses and SRB that cause biofouling in Singapore NEWater and industrial RO systems.
- Non-Oxidizing Formula: Does not attack polyamide or TFC membranes — unlike chlorine, which causes irreversible oxidation damage in Singapore plants.
- SRB Control: Penetrates anaerobic biofilm zones in Jurong Island cooling systems and kills sulfate-reducing bacteria that produce corrosive hydrogen sulfide.
- NEWater & Pharma Safe: Food-grade formulations comply with PUB water quality guidelines and HSA/PIC-S requirements for potable and pharmaceutical applications.
- Biodegradable & Eco-Friendly: Breaks down into non-toxic components, minimising environmental impact at Singapore discharge points.
- System Compatibility: Fully compatible with all RO, NF and UF membrane types, housings and CIP skids used in Singapore.
- Flux Maintenance: Prevents slimy deposits that cause pressure drop and permeate flow decline in Singapore plants.
- Marine RO Specialist: Effective in marine vessel RO units operating in Singapore coastal waters with high microbial load.
Industries We Serve Across Singapore:
NEWater Plants (PUB): NEWater RO systems use non-oxidizing biocide for continuous feed dosing to control algae and biofilm without damaging membranes.
Pharmaceutical Water Treatment (Tuas, Woodlands): Pharma plants use food-grade non-oxidizing biocide for residue-free sanitisation of purified water systems, meeting HSA and PIC/S guidelines.
Marine Vessels & Shipyards: Marine RO units on vessels and offshore platforms in Singapore use non-oxidizing biocide to control biofilm without corroding system metallurgy.
Jurong Island Petrochemical: Large petrochemical cooling towers use non-oxidizing biocide to control SRB and biofilm without corrosion risk.
Semiconductor Ultrapure Water: Semiconductor fabs in Woodlands and Tuas use non-oxidizing biocide for residue-free sanitisation of ultrapure water RO systems.
Food & Beverage Processing: Food factories across Singapore use non-oxidizing biocide for CIP of process water RO systems between production batches.
Non-Oxidizing Biocide vs Chlorine — Why Singapore Plants Prefer Non-Oxidizing:
| Parameter | Chlorine (Oxidizing) | Non-Oxidizing Biocide |
|---|---|---|
| Effect on Polyamide Membranes | Degrades membrane surface | Safe for polyamide and TFC |
| Effect on Cooling System Metallurgy | Corrosive at high doses | Non-corrosive to steel and copper |
| SRB Control | Limited — does not penetrate biofilm | Penetrates biofilm and kills SRB |
| Dechlorination Step | Required before RO membranes | Not required |
Dosage & Application Guide for Singapore RO Plants:
- Continuous Feed Dosing: 2–10 ppm in feed water, depending on microbial load and system volume. Ideal for NEWater and Jurong Island cooling systems running 24/7.
- CIP Shock Dosing: 50–200 ppm during shutdown sanitisation, followed by permeate flush.
- Injection Point: Before cartridge filter and static mixer, on the feed side of the RO membranes.
- Dilution: Can be fed neat or diluted up to 10% with RO permeate water. Never dilute with raw water.
- Monitoring: Track microbial counts, differential pressure and permeate flow to confirm biocide effectiveness.
Common Biofouling Problems in Singapore NEWater, Pharma & Marine RO Systems:
Biofilm Formation: Bacterial slime layers that resist standard cleaning. Non-oxidizing biocide penetrates and breaks down the biofilm matrix.
Sulfate-Reducing Bacteria: Thrive in anaerobic zones of Jurong Island petrochemical cooling systems and produce hydrogen sulfide that corrodes steel and damages membranes.
Algal Growth in NEWater Intakes: Seasonal algal blooms in Singapore reservoir and coastal intakes introduce organic matter and microbial load.
Marine Vessel Biofouling: Marine RO units operating in Singapore coastal waters face high microbial load from seawater and onboard processes.
Semiconductor Ultrapure Water Contamination: Trace microbial contamination in semiconductor RO systems requires residue-free, non-oxidizing disinfection.
Membrane Flux Decline: Biofilm deposits cause gradual but persistent loss of permeate flow and rising differential pressure.

Frequently Asked Questions (Singapore):
Q: What are membrane biocides used for in Singapore RO systems?
A: They control microbial growth and biofouling in RO membranes at NEWater plants, pharmaceutical water systems, marine vessel RO units and Jurong Island cooling towers. They kill bacteria, fungi, algae and SRB that form biofilm on membrane surfaces.
Q: Why are non-oxidizing biocides preferred for Singapore RO systems?
A: Non-oxidizing biocides do not attack polyamide or TFC membranes, unlike chlorine. This makes them the preferred choice for NEWater, pharmaceutical and marine RO systems in Singapore where membrane integrity is critical.
Q: Which Singapore industries use membrane biocides the most?
A: NEWater plants, pharmaceutical water treatment facilities in Tuas and Woodlands, marine vessel RO systems in Singapore shipyards, Jurong Island petrochemical cooling towers, and semiconductor ultrapure water systems.
Q: How do membrane biocides control sulfate-reducing bacteria in Singapore?
A: Non-oxidizing biocides penetrate biofilm and kill SRB without oxidizing metal surfaces, protecting both membranes and system metallurgy in Jurong Island cooling systems and other Singapore plants.
Q: What dosage of membrane biocide is recommended for Singapore RO systems?
A: Typical dosage is 2–10 ppm for continuous feed dosing, or 50–200 ppm for CIP sanitisation. Our team provides free dosage guidance based on feed water analysis for Singapore plants.
