In an effort to lower operational costs and extend the life of the dewatering centrifuge, operators in Springboro, OH, began to look at the polymer activation equipment in use at the plant. The Polyblend® M-Series emulsion polymer activation systems had been in steady operation for over 10 years. The equipment still performed reliably, but operators were interested in ways to achieve greater efficiency. They were aware of the new Polyblend® Magnum mix chamber, with its enhanced two-zone mixing energy.

Few resources are as vital to our health and well-being as clean water and sanitation. What we easily take for granted would not be possible without myriad sophisticated technologies – to be found from water extraction and purification plants, through pumping and delivery, to the efficient removal of wastewater and its processing.

A quality outcome is only as reliable as the components and processes used to create and test it. When it comes to municipal drinking water, food, beverages, wastewater effluent, and other industrial applications, having reliable microbiological testing reference materials to benchmark quality control (QC) processes is essential. Here are some important points to consider when establishing or managing QC programs.

A large utility in Florida, whose sewer collection system handles more than 80 million gallons of wastewater every day, turned to new technologies to improve their cleaning program. 

In this case study, discover how a WWTP used a Mazzei aeration system to continue meeting its permit requirements without adding to the daily responsibilities of plant personnel. 

For water treatment professionals prioritizing precision and efficiency, hollow-fiber microfiltration membranes are revolutionizing the way industries and municipalities treat water.

The City of Cumberland (MD) wastewater treatment plant could see wild swings in its dissolved oxygen (DO) levels until it replaced its air control system with Aerzen AERprocess, an intelligent airflow control system. Now, the city enjoys vastly improved DO control in individual zones and across the entire process, as well as significant savings on its energy bills.

Oostburg’s Black River Falls facility is a lean operation with limitations in space for screening technology and in the staff resources available to manage, maintain and report on the Village’s processes. Even though space was limited, Oostburg knew that putting a headworks screening solution in place would improve their operational efficiency. Oostburg found the perfect solution using the Huber Technology RoK4 confined space vertical screen.

Responsibility for analysis results lies with the users themselves or their supervisors. Both are therefore liable for any incorrect interpretations and decisions that are made as a consequence of incorrect data.

The most common method of aeration for activated sludge systems is diffused air, but the energy costs associated with this process are often the largest non-labor-related expense a wastewater treatment facility has to bear.

This customer supplies district heating and electricity for the region of Sønderborg. For one of their waste applications a MAG meter failed within 6 months, and was successfully replaced with a Panametrics Aquatrans AT600.

There’s a lot to be considered in the price tag of an ultrasonic instrument. Derek Moore from Siemens explains how the historical way of thinking only of capital costs needs to change to the more holistic approach of total expenditures.

Providing the best value to wastewater customers requires a team of operators that have a deep sense of ownership and are committed to continuous improvement. Such is the case for the operating staff at one wastewater treatment plant whose progressive attitude and a philosophy of “do it right” led them to an investment in online instrumentation and SCADA for compliance, monitoring, and control.

The need for of nitrogen-reducing wastewater treatment systems has become more common in the past few decades due to various environmental concerns, including eutrophication, oxygen depletion, and toxicity to aquatic organisms in lakes and streams. The addition of nitrogen removal to any wastewater treatment plant, new or existing, typically increases the costs of the project significantly. When evaluating suitable technologies, it becomes critical to properly identify processes that can not only proved the best upfront capital value but also provide the most sustainable long-term functionality.

Water quality test strips have been around for decades. They are usually constructed from a porous media, including different types of paper, and undergo a color change when dipped into water containing the analyte of interest. These test strips have seen application in swimming pools, aquariums, hot tubs, remediation sites, and other commercial/environmental areas.

This application note explores the importance of maintaining a delicate balance in reverse osmosis systems to protect RO membranes.

Aeration has been a primary method for treating municipal and industrial wastewater for over a century. It is a natural way to reduce biological oxygen demand (BOD) and control odors. In the SBR process, aeration helps foster nitrification by bubbling air through the mixture of wastewater and activated sludge, encouraging the multiplication of aerobic microbes which consume nutrients and convert ammonia into nitrites and nitrates.

A water management company in Serbia used Panametrics' ultrasonic flow meter technology for stormwater management, ensuring reliable measurement and accuracy in challenging conditions. The technology allowed for live monitoring of water transfer and reduced the risk of flooding.

Osmosis is the phenomenon of lower dissolved solids in water passing through a semi-permeable membrane into higher dissolved solids water until a near equilibrium is reached
