In demanding wastewater treatment environments, even the best equipment needs some TLC every now and then. Finding the best way to approach that can have a tremendous impact on the total lifecycle cost of that equipment. Here is how planning ahead to evaluate the range of options and the best choices for the task at hand can make a tremendous difference in both the cost and continuity of equipment performance.

Recognizing pH's pervasive influence empowers operators to achieve consistent and reliable outcomes in every facet of water and wastewater treatment, underlining its indispensability for clean and safe water systems.

Every day our technical support people answer questions on the selection of sensors for pH, ORP, conductivity, dissolved oxygen and turbidity. No issue generates more confusion than cell constants for conductivity sensors. The vast majority of returns we process are for conductivity sensors that were ordered with the wrong cell constant. It turns out that cell constants are something that we all read but that most of us don’t really understand. Pick the wrong cell constant for a probe and your analyzer will happily give you numbers to 3 significant digits. The only problem is those numbers are wrong.

Wastewater is a focal point for public health professionals evaluating levels of COVID-19 community infection. Here are some considerations on the use of membranes for efficient SARS-CoV-2 virus water sample preparation.

American Laboratories, Inc. is a leading manufacturer of enzyme products for many food, dietary supplements, nutritional and industrial applications. The company has grown steadily, currently operating three facilities in Omaha, Nebraska. To keep pace with this expansion, the company realized, some years ago, that a more efficient way to process the enzyme material was necessary. After examining their options, they made a decision to purchase a Franklin Miller DELUMPER® Crusher 1077 S4.

For as many water/wastewater utilities that use SCADA systems inside their treatment facilities, there are many where that automated data collection and control all but ends at the property line. In reality, a significant percentage of customer service and performance efficiency opportunities exist ‘beyond the fence.’ Here is how utilities can use remote monitoring to leverage those opportunities for success.

A contractor needed a reliable pump supplier and service provider with extensive expertise in project planning and implementation, and one that had direct access to sufficient and appropriate pumping equipment.

The City of Plymouth processes 150,000 gallons of raw sewage a day. Before 2009, the plant had no headworks installed at all. The raw sewage was being dumped into a pond. Because of this, the plant suffered major ongoing sludge and BOD problems. A city engineer recommended a new system be installed to combat these problems. After doing research, the engineer found a Franklin Miller system that proved a perfect solution.

Most small towns, all over the world, utilize lagoons for treating their wastewater. Many rural industries also utilize lagoons for storm-water and wastewater treatment. While industrial plants may be able to pay for activated sludge treatment of one design or another, small municipalities simply do not have a choice in treating their small populations’ wastes.

For almost 50 years, CPS Energy of San Antonio has drawn water from the San Antonio River to recharge two man-made lakes that provide cooling water for their power plants.

Waste water, or raw sewage, is water that drains from toilets, sinks, showers, baths, dishwashers, washing machines and liquid industrial wastes.

A wastewater treatment plant separates solids from the liquid, and consists of two basic stages: primary treatment and secondary treatment.

Solids present in wastewater need to be safely and comprehensively treated and removed. This means not only removing toxic compounds, including both organic and inorganic materials such as heavy metals, but also eliminating any harmful bacteria present in the solids.

A static headspace method was developed using Teledyne Tekmar automated headspace vial samplers to meet the method requirements of the Alcohol and Tobacco Tax and Trade Bureau of the US Department of the Treasury (TTB) method SSD: TM:2001 for testing fusel alcohols in alcoholic beverages.

Monitoring phosphate during the wastewater treatment process allows for fine-tuning and optimizing chemical dosing for removal of phosphate, which provides significant cost savings to the plant while protecting the aquatic environment downstream of the facility.

Coriolis measurement has been adopted as a default technology in many application scenarios due to its high accuracy and immunity to process variables (temperature, pressure and flow profile). However, Coriolis wasn't always widely accepted. Two applications, in particular, helped what was once a nascent flow measurement technology gain a foothold in the marketplace.

Level controllers have evolved to meet today’s environmental challenges and industry demands. Learn how they support improved process management and, ultimately, a better bottom line.

Despite their importance in modern wastewater applications, not all DAFs are created equal. Factors, such as the components that make up these systems, will influence how well they work and how long they last.

Polycyclic Aromatic Hydrocarbons (PAHs) are a large group of organic compounds found naturally in the environment. PAHs are monitored by the US Environmental Protection Agency due to their carcinogenic characteristics.
