The clarity of water in a stream, river or ocean is a key determinant in fostering a healthy and balanced aquatic ecosystem. The clearer the water, the greater the ability of light to penetrate to aquatic plants which generate the oxygen needed for aquatic life.
Operating a wastewater facility is no easy task in today’s world. There are many challenges that owners / operators face, including sewage composition, water consumption, and an aging infrastructure.
The Jimo, China, municipal wastewater plant was originally designed to treat a combination of municipal and textile wastewater (120,000 m3/d) with Class IB effluent limits for BOD, COD, ESS, TN, NH3-N and TP.
A landfill operator’s leachate treatment plant in Missouri required pH reduction following lime-softening and prior to the biological wastewater treatment process. Carbon dioxide (CO2) was chosen as a substitute for sulfuric acid due to improved process control and a reduced tendency to form scale.
To increase capacity within the existing footprint of a wastewater treatment facility in Michigan, two existing tanks were converted to aeration tanks with pure-oxygen aeration provided by Praxair’s In-Situ Oxygenation (I-SOTM) System.
The Bissell Point Wastewater Treatment Plant is the largest wastewater treatment facility in Missouri with an average flow rate of 123 MGD. In the mid-1980s, the facility expanded to provide secondary treatment. The goal of the upgrade was to select a reliable process that would achieve high-rate BOD removal.
Lagoons have been an accepted method of wastewater treatment for many years. However, after they are in use for an extended time period, they are often plagued with problems, including odors, sludge buildup, and poor effluent quality. Water Online spoke with Jim Dartez of Reliant Water Technologies to learn how wastewater lagoons work and how to ensure they stay in compliance with regulations.

Now that the final rule has been published in the Federal Register, the stage is set for official implementation of the U.S. EPA’s Steam Electric Power Generating Effluent Guidelines on Jan. 4, 2016.
If you were somehow transported back to the 19th century unawares, the first thing to tip you off might be the smell.
Susan Moisio, conveyance and storage leader with CH2M, sheds light on the conditions and obstacles facing municipalities as they struggle with stormwater management.
There’s no question that they have found their way into our water supply and there’s evidence to suggest they are neutering fish, making birds fat, and exposing drinkers to gender-morphing side effects.
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.
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.
General Manager William Snyder talks about Monroeville, AL’s water distribution system, important features when selecting service brass, and why they prefer to work with Mueller Co. and Consolidated Pipe. This video documents the advantages water utilities and distributors have when sourcing service brass from Mueller.
Pangnirtung is an Inuit hamlet in the Canadian territory of Nunavut, located on Baffin Island. Fredericton based integrator, exp Services Inc., was selected for the nine million dollar renovation of Pangnirtung’s secondary municipal wastewater treatment facility. They chose VTScada for the brand new Supervisory Control and Data Acquisition (SCADA) system which gives the operators the ability to monitor and control the plant, receive alarms and notifications, view historical data trends and report.
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.
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.

Monitoring chlorine and fluoride levels in the drinking water of Utah’s Taylorsville-Bennion Improvement District used to be expensive, labor intensive, and often sensitive to interference from the variable frequency drives used to operate the chlorine injection pumps. That is, until the district upgraded to Rosemount Analytical free chlorine and fluoride sensors and analyzers from Emerson Process Management.
Sustainable approaches to stormwater management are taking hold around the world. One example is the European Union Horizon 2020 funding for Nature-based solutions for climate and water resilience in cities (urban re-naturing) – launched today.
