Ensuring efficient and safe operation of water and wastewater treatment facilities requires powerful pumps and reliable control systems. They play a critical role in ensuring the efficient and smooth operation of these plants by automatically managing pumps and providing valuable data. Below, we look at three noteworthy pump control system solutions.
APG Neuros Advanced Aeration Control System
APG Neuros’ Advanced Aeration Control System empowers water resource recovery facilities to take control of their biological secondary treatment processes. It uses self-learning algorithms referred to as Model Predictive Control to compute the oxygen demand to deliver performance from the entire aeration system. Including optional ammonia-based aeration control unlocks further savings potential by dynamically changing the dissolved oxygen setpoints based on the loading to deliver a reliable and stable ammonia treatment process at the lowest oxygen level, reducing the oxygen requirements for treatment leads to significant reduction in power consumption and therefore reduces the operating costs by as much as 20%. Its Model Predictive Control analyzes historical operational data and raw trends that it uses to enable Advanced Aeration Control to compensate for the nonlinearities inherent to the secondary treatment process. The result is stable and accurate control over the full range of operating conditions without the need for manual re-tuning.

Halogen Valve Systems Terminator Actuator
The Terminator Actuator from Halogen Valve Systems can be used on chlorine ton containers as well 150-pound cylinders to instantly stop the flow of chlorine in case of an emergency. The clamp mount version incorporates the same mounting clamp design as the Eclipse Actuator, allowing it to quickly and securely be installed on ton container valves without the use of any tools. It can be used on containers feeding through a pressure manifold or can be installed side by side with tank-mounted vacuum regulators. The Gemini controller provides DC power and control to one or two Terminators and can be combined for systems with larger quantities of containers. Emergency chlorine shutoff is initiated when the controller receives a close contact signal from a leak detector or included emergency shutoff switch and a relay output provides remote indication that an emergency close sequence has been performed.

Lutz-JESCO America TOPAX MC
The TOPAX MC multichannel controller from Lutz-JESCO America has a modular design that makes it an adaptable and effective solution for all measurement and control technology requirements. It offers automated efficiency — freedom from repetitive control tasks while providing accuracy and reliability. Users can actuate the dosing pumps using an optocoupler or relay and servomotors by using a relay or a 20mA output. The high-resolution, 5-inch color display offers a user-friendly operating interface with a simple touch-control and intuitive navigation menu that can be set to multiple languages. Use four analog outputs (0/4-20 mA) or the network capability to transfer measured values to a web browser or a telemaintenance point. A programmable interval timer can be used to set automatic alerts for wear-related sensor change.
