    Continuous Process Monitoring & Control Systems

What is the IQ Sensor Net (IQSN) System?

IQSN logoThe WTW IQ Sensor Net (IQSN) is a modular and scalable network of controllers and sensors for wastewater treatment plants, ensuring continuous water quality monitoring from influent to effluent. Customizable and expandable, it meets the needs of small, medium and large wastewater treatment plants. WTW IQSN improves operational efficiency, reduces costs, and enhances performance, ensuring compliance and budget control for your water resource recovery facility.

IQSN - overview

Key Components of the IQSN System

The IQ Sensor Net system consists of three primary components: 1) sensors, 2) controllers, and 3) analyzers. Together, these components form a comprehensive and adaptable water quality monitoring system that enhances operational efficiency, reduces costs, and ensures compliance with regulatory standards. The system provides continuous, accurate data from influent to effluent, empowering wastewater treatment plants to maintain optimal performance and control. 

1. Sensors

WTW IQSN Sensors measure a variety of water quality parameters such as pH, ORP, dissolved oxygen, turbidity, nitrate, ammonium, and more. Sends data to controllers for processing.

  • Durable and reliable for continuous monitoring in diverse environmental conditions.
  • Interchangeable to customize the system for specific monitoring needs.
  • Easy maintenance to ensure consistent performance.
