1. Overview of the Programme
The wastewater treatment process includes multiple stages, such as pretreatment, biochemical treatment, advanced treatment, and sludge disposal. It requires precise process instruments to monitor water quality parameters in real time, optimize process control, and ensure that the treated water meets the required standards. FESKS (Feisike) instruments and meters offer a comprehensive solution for the entire process, covering key parameters such as PH, ORP, dissolved oxygen, and turbidity. By integrating devices like electromagnetic flow meters and level meters, they enable data-driven intelligent management.
2. Process flow and instrument configuration
01. Pre-treatment stage (inlet monitoring)
• Monitoring objectives: adjust water quality stability and protect subsequent equipment.
• Core instruments:
• PH meter/ORP meter: real-time monitoring of the acidity and alkalinity and REDOX potential of the influent water to avoid extreme pH or residual oxidant damage to the biochemical system.
Selection advice: FESKS FSPH 5280 series corrosion resistant PH meter, support automatic temperature compensation, suitable for high suspended matter environment.
• Electromagnetic flowmeter: accurate measurement of water inlet flow, providing data benchmark for process control.
Selection advice: FELD 350 series split flowmeter, select the lining and electrode corresponding to the water quality, can adapt to any pipe diameter and water quality.
02. Biochemical treatment stage (aeration tank/anoxic tank)
• Monitoring objectives: optimize aeration efficiency and control sludge activity.
• Core instruments:
• Dissolved oxygen (DO) sensor: real-time monitoring of dissolved oxygen concentration in the aeration tank, and linkage with fans to realize energy-saving aeration.
Selection suggestion: FESKS FSDO-5310Y fluorescence sensor, anti-pollution design, reduce the frequency of calibration and maintenance.
• Sludge concentration meter (MLSS): online monitoring of sludge concentration, guiding the ratio of sludge discharge and reflux, ensuring the efficiency of activated sludge process.
Selection suggestion: FESKS FSSS 5330 infrared scattering sensor, no fear of foam interference, high data stability.
03. Advanced treatment stage (disinfection/filtration)
• Monitoring objectives: Ensure that the effluent disinfection effect and turbidity meet the standards.
• Core instruments:
• Residual chlorine analyzer: monitor the residual concentration of chlorine or chlorine dioxide after addition to avoid secondary pollution caused by excessive addition.
Selection suggestion: FESKS FSCL-5290 constant voltage method residual chlorine meter, fast response speed, suitable for dynamic water quality.
Turbidity meter: detect the turbidity of the water, evaluate the filtration system and sedimentation effect.
Selection advice: FESKS FSTU 5320 online turbidity meter, support multi-range switching, adapt to different water quality scenarios.
04. Sludge treatment stage
• Monitoring objectives: monitoring the liquid level of each treatment tank, sludge thickening and dewatering efficiency.
• Core instruments:
• Ultrasonic level meter/differential meter/mud level meter: real-time measurement of sludge storage tank liquid level/mud level to prevent overflow or pump idling.
Selection advice: FESKS FLEV 200/FLEV 300 non-contact level meter, FLEV 400 mud level meter, strong anti-dew design, suitable for high temperature and humidity environment.
3. System integration and intelligent management
01. Data centralized monitoring platform
• Instrument data is connected to PLC/DCS system through 4-20mA, Modbus and other interfaces to realize the visualization of process parameters.
FESKS provides customized SCADA software to support historical data traceability, trend analysis and alarm push.
02. Energy saving and optimization control
• The dissolved oxygen data is linked to the aeration fan to reduce energy consumption by 20%-30%;
• Residual chlorine/ORP feedback control dosing pump, accurate dosage of chemicals, cost saving.
03. Remote operation and maintenance support
• Optional Internet of Things module to realize remote diagnosis, calibration reminder and fault warning.
4. Core advantages of FESKS products
• High precision: using imported sensor chip, long-term stability is better than the national standard requirements.
• Strong adaptability: IP68 protection level, corrosion resistant electrode material, adapt to the complex working conditions of sewage treatment plants.
• Low maintenance: self-cleaning design (such as air blowing cleaning function), modular structure, reduce downtime.
5. Service guarantee
Technical consultation: free on-site investigation and instrument selection guidance;
• Fast response: 48 hours after-sales engineers arrive at the site;
• Regular inspection: annual maintenance package to extend the service life of the instrument.
This scheme can be further refined according to the specific project requirements (industrial/municipal sewage, treatment scale, etc.). Welcome to contact FESKS technical team for customized solutions!
