Why RO plants need smart controllers

Traditional RO systems rely on manual monitoring and basic PLCs, leading to costly problems.

Membrane Damage

Without real-time pressure and TDS monitoring, membranes degrade faster. Our platform detects fouling early and predicts when to clean, so you avoid unexpected membrane failures and costly replacements.

Manual Monitoring

On-site visits to check readings waste time and resources. Problems go undetected until they become critical failures.

Inconsistent Water Quality

Without automated alerts for TDS spikes or pressure drops, permeate quality fluctuates and can fail compliance requirements.

Everything you need to automate your RO system

TDS & Conductivity Monitoring

Real-time feed and permeate TDS, conductivity, and rejection rate tracking with configurable alarm thresholds.

Membrane Protection

Automatic high-pressure cutoff, low-pressure feed protection, differential pressure alerts, and a real-time Membrane Health Score that tracks fouling progression to extend membrane life.

Automated CIP & Backwash

Schedule and execute CIP cleaning and backwash sequences with multi-step timed actions, sensor-based triggers, and predictive cleaning recommendations that tell you when membranes need attention before performance drops.

Remote Monitoring

Monitor your entire RO fleet from anywhere via the web portal. View readings, control valves, and receive alerts remotely.

Historical Trends

Track membrane health trends, TDS, pressure, flow, and temperature over time with interactive graphs. Monitor fouling rates and cleaning effectiveness to optimize membrane lifespan. Export data for compliance reporting.

Alarm System

Per-sensor configurable thresholds with instant push notifications, escalation rules, and complete alarm history log.
