A control room in the operator's hands.

Vontech manufactures ultrafiltration systems for water treatment plants. Their equipment was controlled by disconnected PLCs with no unified interface. We built a purpose-built touchscreen HMI that gives plant operators a single dashboard for real-time monitoring, one-touch maintenance, and automated scheduling.

Overview

Vontech manufactures ultrafiltration systems for water treatment plants. Their equipment was controlled by disconnected PLCs (Programmable Logic Controllers) with no unified interface. Operators had no real-time view of what the system was doing and had to follow complex manual procedures to run routine maintenance cycles.

We built a purpose-built touchscreen control system (HMI) that gives plant operators a single dashboard to monitor the entire filtration system, trigger maintenance with one tap, and let scheduled tasks run themselves. The interface is designed for industrial environments: large touch targets for gloved hands, a dark theme to reduce screen glare in bright plant conditions, and fault-tolerant architecture built for 24/7 operation.

  • Real-time monitoring of 8 sensors across a 3-membrane filtration system
  • One-touch automated backwash replacing complex manual procedures
  • Scheduled maintenance automation: set it and forget it
  • Intelligent alarms that alert operators before problems become failures
