In the and ensuring compliancecontrolling and managing sludge is a critical factor in ensuring efficient system operation. Sludge level measurement devices play an essential role in optimizing this process.
Context and Challenges of Sludge Level Monitoring
The increasing frequency of heavy rainfall in Vietnam is overloading sewer systems and wastewater treatment plants. sludge washout occurs when hydraulic pressure disperses activated sludge in from small to large treatment plants.leading to the following consequences:
Hậu quả bao gồm:
- Reduced biological treatment efficiency due to the loss of sludge biomass.
- Increased total suspended solids (TSS) and chemical oxygen demand (COD), resulting in non-compliance with discharge regulations.
- Impacts on both small- and large-scale wastewater treatment plants, contributing to water source pollution.
Proactive sludge level monitoring is a vital solution to mitigate these risks.
Optimal Technical Solutions for Sludge Level Monitoring
Continuous Sludge Level Monitoring
Compared to manual measurement methods, continuous sludge monitoring systems using sludge level sensors provide real-time data on the sludge level in primary and secondary settling tanks. The data integrates into PLC systems, automating actions such as:
- Increasing the flow rate of sludge recirculation pumps
- Timely withdrawal of excess sludge to maintain optimal sludge levels.
2. IFL 700 IQ Sensor (WTW)
The IFL 700 IQ sensor utilizes ultrasonic technology, offering numerous benefits for sludge level monitoring::
- Technical Features::
- Accurate sludge level measurement with minimal maintenance requirements.
- Provides an echo profile, distinguishing between sludge, water, and interferences (e.g., air bubbles, scraper equipment).
- Incorporates automatic noise suppression algorithms to ensure reliability.
- Early Detection of Sludge Washout::
- When sludge is dispersed, the sensor emits an invalid signal instead of displaying a sludge washout , enabling early identification of washout risks.
- Customizable to the characteristics of from small to large treatment plants. (depth, sludge concentration) to prevent false alarms.
- Connectivity and Integration::
- Supports data transmission via cable or wireless (MIQ/WL PS module).
- Compatible with Profibus, Profinet, Ethernet/IP, and outputs analog signals (mA) or relays to PLCs.
- Enables simultaneous monitoring of multiple settling tanks with multi-sensor configurations.
Benefits of Continuous Sludge Level Monitoring
- Operational Optimization: Monitoring activated sludge enables timely adjustments, reducing the risk of sludge washoutmaintaining wastewater treatment efficiency, and ensuring compliance with discharge regulations.
- Flexibility:The IFL 700 IQ sensor is suitable for settling tanks of all scales, from small to large treatment plants., từ nhà máy nhỏ đến lớn.
- Cost Efficiency:Minimizes losses due to sludge washout, reduces costs associated with incident management, and lowers equipment maintenance expenses.
