See how Bismarck’s North Burleigh Water Treatment Plant boosted production 64%, reduced operating costs 20%, and improved treatment reliability using an advanced ozone system upgrade.

Modern biosolids management requires sophisticated biological treatment to achieve Class A pathogen reduction and efficient solids destruction. Explore how integrated aerobic digestion and nutrient management technologies provide reliable, cost-effective paths toward regulatory compliance.

Confronted by everyday operating challenges, many decision-makers at drinking water and wastewater organizations do not always have all the time they would like to develop big-picture strategies and tactics for current and long-term concerns. Fortunately, multiple dedicated water-advocacy organizations do. Here are seven areas where water strategists, decision-makers, and other leaders can benefit from those valuable insights.

Knowing that aeration requirements consume 50 to 60 percent of a wastewater treatment plant's (WWTP) energy bill is one thing. Knowing exactly how and when to tweak aeration output to optimize activated sludge process efficiency with minimal energy waste is an entirely different story.

Water and wastewater utilities rely on accurate flow measurement for important process controls. These may include recycle streams, chemical dosing systems, and other operational functions. In addition, regulators require utilities to measure certain flows, such as treatment plant influent and effluent and potable water pumping. Accurate flow measurement is also important for monitoring and reducing unaccounted-for water.

Due to population growth in recent years, Sanessol, the concessionaire responsible for the water supply and sewage treatment of Mirassol and part of Igua Saneamento Group, decided to use a state of the art technology for their new WWTP, Fartura.

Ross Valley Sanitary District in San Rafael, California services approximately 47,000 mostly residential customers over a 27 square mile service area. They have 5 major pump stations, which is where Ross Valley found themselves having the most trouble. The existing channel grinders were simply not reliable. “It was a constant headache,” said Philip Marcantonio, Senior Collection System Worker. “The pumps were ragging up sometimes twice a week and sometimes twice a day.” The plant reported that the machines were not efficient at all. “It was a lot of extra work on us to keep the stations going,” Marcantonio said. On top of that, the constant downtime was causing even more than extra work; it was costing the district a lot of money. They knew this was not a sustainable system to keep their plant and stations running.

How does a contractor navigate the installation of new water and sewer mains in a neighborhood with heavy traffic, narrow roadways and extensive existing underground infrastructure? The answer is the ALPHA™ restrained joint by AMERICAN Flow Control.

Hydrogen Peroxide typically controls odors and corrosion at primary wastewater treatment plant headworks by direct oxidation of hydrogen sulfide (H₂S) within the wastewater.

Replacing mechanical seals twice per year was difficult and expensive for Chester, IL, but a more serious problem occurred when the seals failed with the Mississippi River at flood stage and the sealed lift station underwater.

Limits of Detection and Quantitation are key to understanding analytical instrumentation capabilities, especially when non-optimal process control can lead to damage of sensitive equipment due to insufficiently accurate readings.

Keeping the water in our lakes, rivers, and streams clean requires monitoring of water quality at many points. Over the years ever increasing environmental concerns and regulations have heightened the need for increased diligence and tighter restrictions on wastewater quality.

The textile manufacturing industry encompasses many and diverse processes that rely heavily on the use of water, energy, chemicals, and other resources. Wet spinning, sizing, desizing, scouring, bleaching, mercerization, dyeing and printing are just a few. Monitoring and controlling the pH, TDS/Conductivity/Salt Concentration, ORP (REDOX), and Temperature of the aqueous solutions used in these processes conserves costly resources, controls quality, and reduces the amount of pollution that must be treated before discharge of effluent wastes. This can be done manually with handheld instruments or automatically with in-line monitor/controllers.

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

As old gas & oil fields play out, newer methods must be used to extract resources from areas where they are locked in layers of shale. One current technique is known as “fraccing,” in which high pressure water is pumped into the well shaft to “fracture” the rock layers, allowing more natural gas to escape and be collected. However, this technique poses a number of environmental problems, including contamination of water with hydrocarbons, solid particulates, and scale producing ions — making it unsuitable for reuse.

In the water and wastewater market segment, the LLT100 laser level transmitter provides an efficient way to measure levels of liquids.

In wastewater treatment, aerobic digestion enables plants to increase their capacity by injecting oxygen into the wastewater head space.

Learn how a wastewater treatment plant in eastern Switzerland relies on the targeted use of flocculants to prevent sludge washout. 

Hexanal is one of many well-documented aromatic components that contribute to flavor and aroma in common consumer food products containing omega-6 fatty acids. Hexanal content is also used to measure the oxidative status of foods rich in omega-6 fatty acids.
