# 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.

**8 sensors** Monitored in real-time

**1 tap** To trigger backwash

**Elixir/OTP** Fault-tolerant runtime

**Automated** Backwash and CIP cycles

## 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
