Product Description
PLC Controlled Fully Automatic Dissolved Air Flotation Machine for Smart Operation

This Fully Automatic PLC Controlled Dissolved Air Flotation Machine brings intelligent automation to industrial wastewater treatment, enabling unattended twenty-four seven operation with real-time process optimization. At the heart of the control architecture sits a Mitsubishi programmable logic controller connected to a 7-inch color HMI touchscreen that provides operators with intuitive access to all system parameters, historical trend data, and alarm diagnostics.

The PLC continuously monitors critical process variables including influent flow rate, pH, dissolved oxygen, air saturation pressure, sludge blanket depth, and effluent turbidity through a network of industrial-grade sensors with 4-20 mA analog outputs. Based on these real-time inputs, the controller automatically adjusts chemical dosing pump stroke rates, dissolved air recycle ratio via VFD speed control, and skimmer cycle timing to maintain optimal separation performance regardless of fluctuating influent conditions.

Built-in data logging functionality records all operational parameters at user-configurable intervals, creating a permanent audit trail for regulatory compliance reporting. Remote access capability through an industrial Ethernet port with optional 4G cellular gateway enables off-site monitoring, alarm notifications via SMS or email, and remote troubleshooting by factory engineers without requiring an on-site visit.

Key Features
  • Mitsubishi PLC Core: Industrial-grade programmable controller with ladder logic programming provides deterministic control response times below 10 milliseconds for critical safety interlocks.
  • 7-Inch Color HMI Touchscreen: Intuitive graphical interface displaying real-time process flow diagrams, parameter trends, alarm history, and maintenance reminders with multi-language support for global deployment.
  • Auto-Dosing PID Control: Closed-loop feedback control of coagulant and flocculant dosing pumps based on online pH, turbidity, and flow measurements using proportional-integral-derivative control algorithms for chemical optimization.
  • Variable Frequency Drive Integration: The recycle pump, air compressor, and skimmer drive motors all operate under VFD control, enabling precise speed regulation and significant energy savings during partial-load conditions.
  • Remote Monitoring Gateway: Built-in Ethernet port with optional 4G router enables secure VPN connection for remote performance monitoring, alarm notification, and diagnostic access from any internet-connected device worldwide.
  • Automated Sludge Discharge Logic: Timer-based or sludge blanket level-triggered control of the sludge discharge valve with configurable open duration and frequency to maintain consistent sludge solids concentration.
  • Data Logging for Compliance: Onboard memory stores 12 months of operational data at one-minute intervals, exportable via USB drive or network transfer in CSV format for regulatory reporting and performance analysis.

Applications

The PLC-automated DAF system is the preferred choice for facilities where minimizing operator attention and maximizing process consistency are critical operational objectives. Large-scale food processing plants with multiple production shifts rely on the fully automatic operation to maintain effluent quality through staffing transitions without requiring dedicated wastewater treatment operators on every shift.

Remote mining camps and oil field installations in locations with limited access to skilled labor benefit from the remote monitoring and diagnostic capabilities that allow centralized engineering support to manage multiple distributed treatment systems from a single control room. Electronics manufacturing facilities requiring ultra-consistent water quality for parts washing and surface preparation processes use the automated chemical dosing control to maintain tight parameter bands despite variable production schedules.

Municipal water treatment plants integrate these automated DAF units into their SCADA networks, allowing centralized operators to monitor and control the pre-treatment stage alongside filtration and disinfection processes from a unified interface. Contract wastewater treatment service providers deploy these systems at customer sites under build-own-operate arrangements, using remote monitoring to manage multiple installations efficiently with minimal traveling technician costs while providing guaranteed treatment performance to their industrial clients.

Packaging & Quality Assurance

Each PLC-controlled DAF system undergoes a comprehensive factory integration test where all control loops, sensor calibrations, and communication interfaces are validated against a simulated process environment before shipment. The control panel is shipped as a pre-wired and fully tested assembly requiring only field power and sensor connections during installation.

The mechanical equipment is packed in a reinforced marine plywood crate while the electrical enclosure receives additional waterproof wrapping and desiccant protection. Documentation includes complete electrical schematics with I/O lists, PLC program backup on USB drive, HMI project file, sensor calibration certificates, network architecture diagram, and a step-by-step commissioning manual.

Our standard warranty covers 12 months of defect-free operation for both mechanical and electrical components. Optional extended warranty and service level agreements include quarterly remote system health checks, annual on-site preventive maintenance, and guaranteed 4-hour remote response time for critical alarms to ensure maximum system availability for your production-critical wastewater treatment operations.
