Water Treatment
Water Treatment
Onnovo provides advanced biocidal solutions like Bronopol, DBNPA, CMIT/MIT, Glutaraldehyde, PHMB, and Quaternary Ammonium Compounds, effectively controlling biofilm and microbial growth in various water systems. Our recommendation process starts with fully understanding your water system’s unique challenges to ensure the RIGHT CHEMISTRY.
Understanding Water Treatment & Its Microbial Challenges
Water is a critical resource in municipal, industrial, and commercial applications, requiring strict microbial control to ensure safety, regulatory compliance, and system efficiency. Bacterial, fungal, and algal contamination in water systems can cause biofilm buildup, corrosion, fouling, and health hazards.
Without proper microbial management, water treatment systems can become breeding grounds for harmful bacteria, leading to equipment failure, public health risks, and regulatory violations.
Key Microbial Challenges in Water Treatment
- Biofilm Formation in Pipelines & Equipment – Bacteria form protective biofilms, reducing flow efficiency and increasing clogging & corrosion.
- Pathogenic Bacteria & Legionella Risk – Harmful microbes like Legionella, E. coli, and Pseudomonas pose severe health hazards in drinking water and cooling systems.
- Algal & Fungal Growth in Reservoirs & Cooling Towers – Algae and fungi reduce water clarity, disrupt chemical balance, and lead to foul odors & discoloration.
- Scaling & Corrosion Due to Microbial Activity – Sulfate-reducing bacteria (SRB) produce hydrogen sulfide (H₂S), accelerating metal corrosion & infrastructure damage.
- Regulatory Compliance & Environmental Concerns – Water treatment processes must comply with EPA, WHO, and local health standards while using sustainable biocides that minimize environmental impact.
Types of Water Treatment Systems & Their Microbial Risks
Water treatment applications require specialized antimicrobial strategies to ensure clean water, prevent contamination, and extend system lifespan.
| Water Treatment Type | Common Applications | Microbial Risks & Required Protection |
|---|---|---|
| Cooling Water Systems | Industrial cooling towers, HVAC, power plants | Legionella risk, biofilm fouling, scale formation |
| Boiler & Process Water | Steam generation, energy production, manufacturing | Corrosion by sulfate-reducing bacteria (SRB), scale deposits |
| Wastewater Treatment | Industrial effluent treatment, municipal wastewater | Sludge formation, odor control, effluent microbial contamination |
| Closed-Loop Water Systems | Chilled water circuits, heating systems | Biofilm growth, microbial-induced corrosion (MIC) |
| Municipal Drinking Water | Public water supply, desalination, potable water processing | Pathogenic bacteria, biofilm buildup, regulatory compliance |
Risks of Microbial Contamination in Water Systems
Without proper microbial control, water treatment systems face severe operational, financial, and health risks:
- Public Health Hazards & Legal Liability – Contaminated water can cause outbreaks of Legionnaires’ disease, E. coli infections, and other waterborne illnesses.
- Pipeline & Equipment Fouling – Biofilm formation leads to blockages, reduced water flow, and increased maintenance costs.
- Corrosion & Infrastructure Damage – Microbially influenced corrosion (MIC) weakens pipelines, storage tanks, and heat exchangers, leading to costly repairs and downtime.
- Reduced Efficiency in Cooling & Boiler Systems – Scaling and microbial fouling lower heat exchange efficiency, increasing energy consumption and operational costs.
- Regulatory Non-Compliance – Water treatment facilities must meet EPA, WHO, and ISO standards to ensure safe and legally compliant water supply.
