Detecting oil slicks on the water surface, especially in raw water sources, is a pressing issue for water supply plants. Oil is a complex pollutant that is difficult to treat and completely remove from water.
Oil contamination in water not only disrupts water treatment but also poses a significant threat to human health. Early and automated detection of oil spills is essential to prevent pollution and protect public health.
Tác Hại Của Váng Dầu Trong Nguồn Nước
Oil is a particularly serious pollutant when present in raw water sources. It not only causes unpleasant odors but also reduces water quality, harms ecosystems, and endangers human health.
Oil in water hinders gas exchange, reduces dissolved oxygen levels, severely damages aquatic plants and animals, and disrupts ecological balance.
In terms of health, the chemicals and heavy metals in oil can cause cancer, endocrine disorders, and skin and respiratory problems when people come into contact with or consume contaminated water. For water treatment processes, oil causes many difficulties, clogging equipment and increasing operating costs.
Overall, the presence of oil in raw water sources not only reduces water quality but also causes significant economic damage due to high treatment costs and negative impacts on the environment and public health.
Therefore, for a water supply plant using surface water, how to quickly detect oil slicks on the water surface, even with very small amounts of oil, is crucial to take timely action before the water enters the treatment process. váng dầu trên mặt nước dù là với lượng dầu rất nhỏ để kịp thời hành động trước khi đưa vào quy trình xử lý nước cấp.
Recognizing this as a critical issue, Viet An has presented a solution to customers for the rapid detection of oil slicks from a height of up to 10 meters above the water surface without human supervision.
This device operates based on UV principles and detects any oil slicks, from diesel to vegetable oils and even jet fuel.
When detecting oil on the water surface, this device will quickly send an alert through the plant's SCADA system or through the IoT Platform iLotusLand. This helps the plant's operators to quickly detect oil spills, stop the pumping system, and respond promptly to the incident.
What Standards Should an Oil Film Detector Meet?
To effectively detect and manage oil spills on the water surface at the raw water source, an oil film detector must meet the following stringent standards and requirements:
High Sensitivity and Accuracy
- Ultra-thin oil film detection: Capable of detecting oil films as thin as 1 µm, ensuring even the smallest oil quantities are detected.
- High accuracy: Provides precise results, minimizing false alarms to guarantee timely and efficient response.
Continuous and Automated Operation
- Hoạt Động 24/7: Thiết bị cần hoạt động liên tục cả ngày lẫn đêm mà không cần sự giám sát của con người.
- Automation: Automatically detects and sends alerts upon oil film detection, preventing timely pollution.
Rugged Design for Harsh Environments
- Weatherproof: Operates effectively in all weather conditions, including extreme temperatures, humidity, and harsh environments.
- Durable construction: Constructed from durable materials like anodized aluminum or stainless steel, corrosion-resistant, and designed to withstand explosive atmospheres (ATEX certified).
Easy Installation and Low Maintenance
- Non-contact measurement principle: Minimizes fouling and reduces maintenance requirements.
- Simple installation: Easy to install and adjust to various conditions, from 0.3m to 10m above the water surface.
Connectivity and Data Transmission
- Diverse connectivity: Integrates with management and monitoring systems like SCADA or IoT platforms through protocols such as RS-485, 4-20mA, Ethernet, Wi-Fi, GSM, etc.
- Real-time data transmission: Sends alerts and data in real-time to ensure a swift response to oil spills.
International Certifications and Standards
- CE and US EPA certifications: Ensures compliance with international quality and safety standards.
- IP68 protection: Completely waterproof and dustproof, suitable for harsh environments.
Long Lifespan and Low Operating Costs
- 5-year LED lifespan: Ensures long life and reduced maintenance frequency.
- Low maintenance costs: Optimizes operating costs, ensuring cost-effectiveness for users.
LDI ROW Aluminum Oil Film Detector: The Optimal Solution
Recognizing the importance of this issue, Viet An introduces the LDI ROW Aluminum oil film detector for water surface detection. This device is designed to operate automatically and continuously 24/7, even in harsh environmental conditions.
Operating Principle
The LDI ROW Aluminum device operates based on UV detection. A UV LED beam excites the oil molecules in the water, producing natural fluorescence. A telescope within the system collects this fluorescence signal and transmits it to the controller for data processing. The received signal is analyzed immediately, allowing for real-time detection and alerting of oil presence on the water surface.
Outstanding Advantages
- Continuous 24/7 operation: The device can operate continuously, day or night, and in harsh environmental conditions.
- No human supervision: The device operates fully automatically, minimizing the need for human supervision.
- High sensitivity: Capable of detecting oil films as thick as 1 µm, ensuring high sensitivity and accuracy.
- Non-contact: The device uses a non-contact measurement principle, making it easy to install, free from fouling, and requiring minimal maintenance.
Wide Range of Applications
The LDI ROW Aluminum device can detect various types of oil, such as engine oil, turbine oil, vegetable oil, lubricant oil, hydraulic oil, mineral oil, marine oil, crude oil and fuel, heat transfer oil, diesel, gasoline, kerosene, and jet fuel (JetA). This makes the device an ideal solution for the water supply and industrial sectors.
