Wastewater treatment control and remote monitoring

Industry Background

Municipal and industrial wastewater treatment facilities operate across vast, geographically scattered geographic locations. Traditional plant management faces severe operational bottlenecks, including prolonged manual inspection cycles, delayed discharge tracking, and high maintenance costs at remote pumping stations. To secure compliance and control overhead, modern wastewater enterprises require reliable, automated infrastructure that can transmit active field status loops without interruption.

System Overview

This engineering deployment presents a comprehensive automation layout utilizing Samkoon’s rugged HMI hardware and high-speed PLC control loops. By establishing real-time field data logging and secure remote network tracking across multiple sedimentation tank nodes, the solution optimizes chemical dosing precision, ensures continuous effluent compliance, and drastically reduces downtime for regional system integrators and water treatment operators.

System Configurations

Process Flow & Control Architecture

The wastewater sedimentation matrix relies on physical gravity settlement loops to separate finer suspended particulates and biomass sludge from water streams. Primary sedimentation tanks focus on separating inorganic solids characterized by lower moisture tracking. Secondary sedimentation tanks, positioned down-line from biochemical treatment blocks, manage organic biomass sludge with higher fluid retention. The underlying automated control sequences execute the following real-time rungs:

• Automated Lifting Pump Control: When the high-sensitivity level transmitters register that the wastewater has exceeded pre-set high-water boundaries, the lifting pump starts automatically to manage system balancing.
• Chemical Dosing & Flocculation Loops: The PLC accurately meters specialized flocculants (PAC), coagulants (PAM), and acid/alkali solutions based on localized process variables. This accelerates biological sludge settlement rates and neutralizes effluent water quality.
• MBR Filtration & Backwash Sequencing: For advanced configurations utilizing Membrane Bioreactor (MBR) technology, the FAs PLC tightly coordinates cross-unit water production pumps, aeration blowers, and automated valves to execute alternating production loops and high-pressure chemical backwash cycles based on absolute runtime parameters.
• Sludge Discharging & Unified Dewatering: Concentrated sludge collected at the base of the sedimentation structure is cyclically purged via automated sludge valves, return lines, and high-pressure sludge dewatering filters for safe disposal.
• Aeration Blower & Oxygen Control: The control matrix monitors dissolved oxygen (DO) metrics in real time, automatically throttling industrial air blowers to maintain optimal biological oxygen saturation within the reaction basins.
• Flow Pusher Logic: Submersible flow pushers are systematically controlled to eliminate structural dead zones and maintain continuous, non-settling fluid velocity profiles throughout the mixing segments.

HMI System Interfaces

• Sedimentation Node 1 Interface: Active diagnostic layout displaying real-time parameters for dephosphorizer dosing, PAM/PAC chemical pumps, lifting pump states, aeration fans, and automated sludge valve timing.
• Sedimentation Node 2 Interface: Specialized visualization screen tracking automated PAM/PAC dosing parameters, MBR water production pump runtimes, high-pressure backwash cycles, and sludge return valve positions.
• Sedimentation Node 3 Interface: Streamlined monitoring dashboard visualizing active flow pusher velocities and blower fan electrical metrics.
