Deterministic Control

Eliminating Manual Operator Subjectivity

Manual valve adjustments, irregular filter backwashes, and visual dosing estimates are the predominant root causes of industrial water plant failures. When an operator forgets to backwash a multimedia vessel, differential pressure crushes media beds or pushes turbidity downstream into expensive reverse osmosis membranes.

Tovila engineers water treatment automation that removes operator guesswork. Industrial instrumentation — differential pressure cells, magnetic flow meters, toroidal conductivity transmitters, and digital pH/ORP probes — feeds continuously into programmable logic controllers (PLCs). The system automatically initiates backwashes, balances chemical dosing loops, alternates duty pumps, and trips fail-safe isolation valves before out-of-spec water reaches downstream processes.

Hardware Robustness

Industrial-Grade Architecture

Built on industry-proven PLC platforms housed in ingress-protected enclosures. Every control panel features optical isolation, 24VDC control circuits, surge suppression, and intuitive human-machine interfaces (HMIs) for clear plant status visibility.

Note: PLC manufacturer platform, I/O count, SCADA protocol compatibility, and telemetry modules are determined during the engineering assessment for that site.

Control Capabilities

Integrated Automation Layers

Protecting pumps, membranes, and product quality through automated closed-loop control.

Automated Backwash & Rinse Cycles

Multimedia, carbon, and softening vessels initiate regeneration sequences based on differential pressure thresholds or cumulative treated volume, preventing media channeling and compaction.

  • Differential pressure transmitters across vessel heads trigger automated valve banks
  • Pneumatic or motorized actuated valve manifolds with limit switch feedback
  • Interlocked sequencing prevents multiple filters from backwashing simultaneously

Dynamic Chemical Dosing Control

Proportional-integral-derivative (PID) feedback loops modulate chemical injection pumps based on real-time flow pacing, pH correction, or chlorine oxidation-reduction potential (ORP).

  • Digital metering pumps with 4-20mA speed modulation
  • Dual inline pH and conductivity measurement verification
  • Low-level chemical tank interlocks alert operators before run-out

Pump Protection & Duty Alternation

High-pressure and booster pumps are protected by hardware interlocks against dry running, cavitation, thermal overload, and high discharge pressure deadheading.

  • Vessel low-suction pressure switches and ultrasonic tank level cutoffs
  • Variable frequency drive (VFD) soft starting to eliminate hydraulic water hammer
  • Automated duty/standby lead-lag pump runtime balancing

SCADA Integration & Remote Telemetry

Local touch-panel HMIs provide graphic process flow visualization, while industrial telemetry links plant data into centralized facility SCADA networks or secure remote monitoring dashboards.

  • Standardized industrial protocols including Modbus TCP, Profinet, and Ethernet/IP
  • Historical trending of normalized flows, pressures, and conductivity metrics
  • Automated alarm dispatch via SMS and email for critical fault conditions
Safety & Compliance

Fail-Safe Logic & Emergency Shutdown Protocols

Tovila programs every control system with hardwired emergency stop safety relays and fail-closed actuator logic. In the event of main power loss, air pressure drop, or out-of-spec conductivity, motorized divert valves instantly isolate downstream distribution and vent high-pressure circuits, safeguarding industrial assets from contamination.

Site Specifics

Control panel enclosure IP ratings, PLC hardware specifications, sensor ranges, and HMI display sizes are tailored during the engineering assessment for that site.

Questions & Answers

Frequently Asked Questions

Can this integrate with our existing plant control systems?

Yes. Control architecture is designed to integrate into existing plant SCADA, DCS, or building management systems (BMS). We support standard industrial fieldbuses including Modbus TCP, Profinet, and Ethernet/IP, with tag maps defined during detailed engineering design.

Does this include remote monitoring?

Remote monitoring capability is part of our standard automation scope. Facilities can monitor transmembrane pressures, flow rates, water quality trends, and active alarms remotely via secure cloud gateways or local network clients.
