ABB Frequency Converters for Waste Water Treatment Plants

ABB now offers the ACQ550 Series variable frequency converter to protect, supply and recycle water. System reliability, pump efficiency and a suite of industry-specific controls enable waste water treatment plants to successfully maintain a reliable water cycle management system. With this in mind, ABB designed a variable speed AC drives specifically for Water/ Wastewater environments and applications. These devices are available, as standard, for panel-mounting or factory direct NEMA-1, drip-proof NEMA-12 or outdoor-rated NEMA-3R enclosures.

A water industry start-up assistant resides within the intuitive, full graphic display panel to aid in commissioning submersible, centrifugal or positive displacement pumps. This control panel can also be mounted remotely, or on the cover of the drive, and used to upload, store and download parameters in multiple drive setups.

Application Control

The extensive library of pre-programmed, water-specific application macros allows rapid configuration of inputs, outputs, and parameters to maximize convenience and minimize start-up time. To simplify troubleshooting, the drive uses a real-time clock, which allows for accurate time stamps on faults, resets and more. Two integral option slots, that can be configured for additional relay outputs (i.e. drive status indications, timed or pump staging applications) or a variety of different communication bus adapters, are at your disposal.

Cost savings

ABB Frequency Converters for Waste Water Treatment PlantsThe ABB ACQ550 variable frequency converter is designed for solutions to give wastewater treatment plants the most flexible motor control performance through two standard modes: Scalar (V/Hz) for typical pumps; and Sensorless Vector for the more demanding applications. By using either these modes, the drive will have accurate speed control of any standard induction motor.

ABB designed the ACQ550 to save save energy by applying variable electronic speed control to pumps and pumping systems. These savings can be achieved over bypass or valve-operated flow control, traditional diesel driven systems or across the line operations. The Affinity Laws of physics define the relationship between pumps and the power they require. On centrifugal pump applications, the power requirement of the pump varies by the cube of the speed. Electronically reducing the pump speed by 20% will typically cut energy costs in half. Designed for water The ACQ550 – which ranges from 1 to 550HP – is well-suited to meet customer demands, from the simplest pumping applications, through the most demanding. Introducing an industry-driven approach, a growing network of Water and Wastewater experts, and the new ACQ550 industry-specific variable frequency converter.
