A Control Room in the Operator’s Hands
Client: Vontech (Water Treatment Equipment Manufacturer)
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
Built with: Elixir/OTP, React, Electron, Phoenix WebSockets
