As Shanghai CAMP Environmental Protection Technology Co., Ltd., established in 2015 and serving global markets including North America, Europe, Asia, and Oceania, we present our advanced Industrial DAF System with UV Disinfection. Engineered specifically for rigorous marine ballast water treatment, this integrated solution tackles invasive aquatic species and pathogens effectively. Our system combines proven dissolved air flotation technology with high-efficiency UV disinfection, offering vessel operators a reliable method to meet IMO D-2 discharge standards. Manufactured in Shanghai, this system reflects our commitment to delivering robust environmental technologies to the international maritime industry.
Core Technology & Operation:
Two-Stage Purification: The DAF unit first removes suspended solids, oils, and organic matter through micro-bubble flotation. Treated water then flows through the UV reactor where high-intensity ultraviolet light neutralizes bacteria, viruses, and microorganisms without chemicals.
Synergistic Efficiency: Pre-treatment via DAF significantly improves UV transmittance (UVT), enhancing disinfection efficacy while reducing fouling on UV quartz sleeves and lowering operational costs.
Automated Control: An integrated PLC-based control system continuously monitors turbidity, flow rate, UV intensity, and dosage, enabling real-time adjustments and ensuring consistent compliance.
Technical Specifications & Performance Data:
| Parameter | Specification |
|---|---|
| Typical Flow Rate Range | 50 - 500 m³/h (Customizable) |
| UV Lamp Type & Life | Medium Pressure Amalgam, 8,000-12,000 hours |
| DAF Hydraulic Loading | 5 - 15 m³/m²/h |
| Power Supply | 380V/50Hz (Customizable for vessel requirements) |
| TSS Removal Efficiency | > 90% |
| Disinfection Performance | Meets IMO D-2 Standard ( |
Key Advantages for Marine Operators:
Compliance Assurance: Reliably achieves the strict biological discharge limits mandated by the IMO BWM Convention, preventing port state control issues.
Reduced Chemical Dependency: UV disinfection eliminates the need for hazardous biocides, simplifying crew handling and port discharge regulations.
Compact Footprint & Modularity: Skid-mounted design simplifies installation and integration into newbuilds or retrofits, minimizing engine room space requirements.
Lower OPEX: Combined DAF pre-filtration extends UV lamp and sleeve cleaning intervals, significantly reducing energy and maintenance costs compared to standalone UV systems.
Durability: Constructed primarily with corrosion-resistant stainless steel (SS316L optional) for harsh marine environments and long service life.
Trusted Global Solution:
Backed by Shanghai CAMP's nearly decade-long expertise (since 2015) and proven track record across diverse markets—from Northern Europe to Southeast Asia, Africa to Oceania—this system embodies robust engineering for global maritime applications.

Frequently Asked Questions (FAQ):
Q: Why combine DAF with UV instead of using UV alone?
A: DAF effectively removes suspended solids and organic matter that can shield organisms from UV light and foul quartz sleeves. This pre-treatment significantly boosts UV disinfection efficiency and reduces maintenance frequency.Q: How does this system handle varying water quality (e.g., turbidity) in different ports?
A: The integrated PLC automatically adjusts air saturation in the DAF unit and modulates UV intensity based on real-time sensor feedback (turbidity, UVT, flow), ensuring consistent performance regardless of inlet conditions.Q: What is the typical installation timeframe for a retrofit?
A: The skid-mounted, modular design facilitates installation. Typical retrofit projects take 2-4 weeks, depending on vessel accessibility and integration complexity. Pre-commissioning tests are conducted shore-side.Q: Is the system suitable for both saline and brackish ballast water?
A: Yes, the system is designed to handle the full range of salinities encountered in ballast water operations. Material selection (e.g., SS316L) ensures corrosion resistance.Q: How energy-intensive is the UV component?
A: Medium-pressure UV lamps offer high intensity with efficient power use. The DAF pre-treatment reduces the UV load, making the overall system energy consumption competitive. Specific power draw depends on flow rate and water quality.Q: What maintenance is required, and how often?
A: Key maintenance includes periodic DAF tank sludge removal, UV quartz sleeve wiping (frequency depends on water quality, reduced by DAF), and annual lamp replacement. The control system provides maintenance alerts.Q: Can the system be upgraded if future regulations become stricter?
A: The modular design allows for potential upgrades, such as adding more UV lamps or enhancing the DAF unit. The control system can be reprogrammed for new protocols.Q: Do you provide commissioning support and crew training?
A> Yes, comprehensive commissioning by our engineers is standard. We also provide detailed operational manuals and onboard crew training sessions to ensure smooth operation.
