Picture 45. The standard wastewater treatment process
Standard wastewater treatment process
Trash screen: the industrial wastewater treatment process starts from the trash screen.
Industrial wastewater will be collected into the collection tank. Passes through an automatic scraper that holds the raw waste into a container in the collection tank. Here, devices are also installed to measure pH and SS concentrations of input industrial wastewater. This is the most important processing step that determines up to 99% of the efficiency of the treatment system.
Collection tank: The collection tank in the wastewater treatment system is a place to gather, regulate the flow and sediment of wastewater from many different sources before moving to the next treatment stages to protect the environment and protect the environment. Optimize system performance.
Fine Trash Filter: Removes small solid objects to protect downstream equipment and treatment tanks.
Grease Separator: Separates and removes grease from wastewater, prevents clogging and protects biological treatment equipment.
Conditioning Tank: Regulates the flow and concentration of pollutants, ensuring the stability and efficiency of the treatment system.
SBR tank: Biological treatment of wastewater through decomposition of organic matter and removal of pollutants.
48
e Disinfection Tank: Kills or neutralizes harmful microorganisms in wastewater with chemicals or ultraviolet rays.
ôỔ Sludge Storage Tank: Stores sludge from the wastewater treatment process before processing or transporting it to the sludge treatment site.
Smart Monitoring and Control System Overview:
Description: Build a smart monitoring and control system that integrates IloT (Internet of Things) technology and artificial intelligence (AI) to monitor and manage the entire wastewater treatment process.
Objective: Minimize risks by detecting problems early, optimizing the treatment process, and ensuring compliance with environmental standards.
Main Components:
e IoT Sensors:
o Function: Attach sensors at key points in the wastewater treatment system to continuously monitor parameters such as pH, temperature, turbidity, pollution levels, and water flow.
o Benefits: Timely detect abnormal fluctuations, reduce the risk of environmental incidents.
e Aland Machine Learning System:
o Function: Analyze data from IoT sensors to predict possible problems and optimize the wastewater treatment process.
o Benefits: Improve operational efficiency, reduce processing costs, and enhance emergency response.
e Centralized Dashboard:
o Uses: Integrate data from all sensors into a central dashboard, providing a comprehensive view of system status in real time.
o Benefits: Help managers and technicians make quick and accurate decisions based on real data.
Operation Process:
e Continuous Monitoring:
o IoT sensors continuously collect data and send it to the control center.
o The AI system analyzes the data to detect potential anomalies or trends.
e Early Warning:
o When risks are detected, the system automatically sends alerts to the management team and technicians via mobile app or email.
o Corrective measures can be deployed promptly, minimizing the risk of major incidents.
e Process Optimization:
o AI systems continuously learn and improve processing based on collected data, suggesting adjustments to improve efficiency.[10]
