The Liquiline System CA80AM ammonium analyzer is designed for monitoring critical control points in water and resource reclamation facilities. The analyzer and sample preparation system defines a modern approach to process control and regulatory compliance, and will be extended as a platform across a range of measurement parameters.
In the membrane degassing process, N2 combo mode is commonly used to achieve high O2 removal performance to a ppb level. However, because a N2 supply is needed in N2 Combo mode, running costs increase significantly and immense space is needed for a N2 supply device. To resolve this issue, SEPAREL® delivers exceptionally high O2 removal performance using only vacuuming. Consequently, initial and running costs are reduced. Additionally, SEPAREL delivers a variety of benefits, such as space and weight reduction.

Protecting wastewater treatment facilities requires operators to think strategically about their unique challenges and identify the best solution for their specific requirements. Specifying the appropriate headworks system for the plant’s needs is arguably one of the most important design decisions a public works engineer will make.
When it comes to disinfection at treatment plants, chlorine has quite the reputation. To some, it’s known as a reliable and trusted solution. To many others, especially among the public at large, it’s looked at with skepticism and concern – but that may be simply a matter of not knowing the facts. Either way, it’s one of the ubiquitous aspects of water and wastewater disinfection… and for good reason.

In this recorded webinar, Chris Huxley from BMT WBM will be using his more than a decade’s experience in 2D Modeling to build your confidence from the ground up in the 2D Modeling space.
Supervisory control and data acquisition (SCADA) systems are the digital pulse of water and wastewater treatment plants. Serving as the information hub, SCADA makes the most of the day’s cutting-edge technology and in turn uses it to make the most of the plant’s operations. But how to keep up with a system that evolves as quickly as the greatest minds in the field will allow?
If wastewater treatment plant operators have nightmares, it’s a good bet that many of them have to do with sewage overflows. Few events are as catastrophic for a wastewater facility as a surge of water it can’t process being churned out into the public sphere, in violation of environmental regulations, and to the detriment of public health.
Wonderware InTouch has been the world’s number one Human Machine Interface (HMI) for over 25 years and offers legendary ease of use, market leading innovation, unequalled investment protection, brilliant graphics, unsurpassed connectivity, the industry’s best support and the broadest partner ecosystem.
Sometimes it’s hard to keep in mind that the water falling over our heads was recently halfway across the world. Or that for all of our differences as people on this planet, we all rely equally on that precious resource. Problems that plague one water system can be felt thousands of miles away. The same goes for wastewater.
Nobody wants to think about the worst case scenario but if you’re responsible for water treatment at an industrial plant, you can’t avoid it. There are any number of things that can force a plant to go offline and it’s imperative that a contingency plan is in place for such an event. Luckily, there are mobile equipment suppliers that can keep things running during an outage, planned or otherwise. Water Online spoke with one provider of such a service, Evoqua Water Technologies, about how it keeps plants running no matter what.
Thanks to VTScada’s integrated design, every new application includes pre-configured databases that support an unlimited number of process alarms and events. Additionally, the standard VTScada Alarm Page provides an instantly intuitive alarm management interface. This approach reduces integration time and ensures that your mission-critical alarm features remain tightly integrated over the life of your system no matter how many times you expand your application or update VTScada.

This video documents the advantages water utilities and distributors have when sourcing service brass from Mueller.
Cutting off service to a customer who hasn’t paid their water bill can be a controversial move for many utilities. But a new product that integrates a shut off valve with an ultrasonic meter may make what has traditionally been an all or nothing decision a little easier.
To achieve its plan to double the Company’s reach, Evoqua is looking to add to its team and ensure it continues to have the best talent in the industry.
In today’s connected world, remote monitoring of water or wastewater system assets is available to any size of utility. As enterprise systems for the large cities continue to evolve in their complexity, nimble cloud-based solutions where the data is housed outside of the utility are offering an affordable monitoring platform to smaller cities and distribution networks.
Be honest – how many times would you answer yes to the following questions?
VTScada provides maximum flexibility when choosing monitoring and control devices by supporting most standard and many proprietary I/O protocols. Let us know if you don’t see a driver you need. We can create new drivers to suit almost any need.
Living near water requires that we plan for situations when we have too much of it. Throughout history we have dealt with flooding when weather events exceed “normal” parameters.
Choosing the company that will fill your water service needs is like making any other long-term commitment. It’s important to do your homework, identify the areas that are most important, and take the time necessary to find a good match.
This video explains the concept of Aquis and how water utilities can benefit from implementing Aquis in terms of providing complete overview of the network as well as being a valuable optimization tool.
This video is a Customer Case for Aquis and Esbjerg, demonstrating how Esbjerg Utility has benefitted from implementing Aquis. The various departments at Esbjerg Utility are working together sharing information in the individually customized user interfaces and working on the same platform.
With Aquis the network is divided into several manageable control zones. This enables operators to react intelligently and responsibly. Contaminated areas can be shut down and adjacent areas isolated from the contaminated area so that the supply maybe maintained normally. Contingency plans can be quickly implemented.
