Sequetrol IoT Controller for SBR Plants

Sequetrol® IoT: Smart Control Unit for Decentralized Sewage Treatment Plants

Powerful, Connected, and Customizable Wastewater Management

In the age of digital transformation, decentralized wastewater treatment systems require more than just reliability—they demand intelligence, connectivity, and adaptability. The Sequetrol® IoT from BONNEL is a cutting-edge control unit engineered specifically to meet the complex needs of modern sewage treatment, including both Sequencing Batch Reactor (SBR) and continuous flow plants.

Equipped with onboard Wi-Fi, an integrated webserver, and optional GSM communication, the Sequetrol® IoT allows users to access and control treatment processes from any browser on a phone, tablet, or PC—no app installation required. Whether servicing a remote site or managing a large system with a touchscreen interface, the Sequetrol® offers seamless access anytime, anywhere.

Under the hood, this compact unit packs impressive hardware: up to 8 relay outputs, 3 digital inputs, and a 4–20mA analog input for flexible process design. With pressure-sensor-based water-level detection, users can eliminate float-switch failures and precisely manage multiple tanks. Built to scale, it enables simultaneous operation of SBR and continuous processes—ideal for applications like duplex buffer-pump control.

Sequetrol® IoT shines in system integration. Through a RESTful HTTP-JSON interface, it communicates effortlessly with SCADA, PLCs, and cloud servers, supporting platforms such as .NET, Python, Java, and JavaScript. For plant developers and service providers, BONNEL’s intuitive MenuMaker 4 PC software empowers non-programmers to create custom control logic, menus, alarms, and logging without coding expertise.

The IoT capabilities also open new business models: implement pay-per-use solutions, offer remote operation as a service, or monitor performance for PPP contracts using built-in telemetry support via the BONNEL Aquavisor®.

Built with robust IP54 connectors, a graphical LCD, acoustic alarms, battery backup, and optional UV-resistant casing, the Sequetrol® IoT is as durable as it is intelligent. Whether you're designing compact rural systems or smart urban microplants, this all-in-one controller brings high-end automation to decentralized sewage treatment.
