The Franklin Miller DIMMINUTOR was selected for the state-of-the-art sewage system infrastructure project built to accommodate the Olympic Winter Games in Sochi, Russia. After an intensive construction project, multiple Model DM36XF DIMMINUTOR® open channel comminutors were employed throughout the new sewage system. Each unit has the capability of 29 million gallons of raw sewage per day.

Pushed beyond the limits of its banks, the Mojave River gushed at more than 36-cubic-feet-per-second in the Upper Mojave Narrows. It was an environmental catastrophe and needed attention immediately.

The chemistry of optimizing water/wastewater treatment extends far beyond chlorine and oxygen. It also involves synthesizing productive insights from the flood of IT data generated by operational technology (OT) sensors, instruments, and control systems. Here’s how better operational intelligence strategies are helping IT and OT personnel collaborate to make processes more cost-efficient.

Special precast box culverts were used for one of the most significant segments of the $25.8 million emergency water restoration project, designated by the NRCS, known as the Cache Water Restoration Project (CWRP). The CWRP project involved the reconstruction and improvement of approximately six miles of mostly open, unlined channels that make up the Logan and Northern, as well as the Hyde Park and Smithfield canals. The project incorporated new precast pipeline, box culverts, a section of pressurized pipe, metering systems, turn-outs, head gates, and improved maintenance access.

Rapid City is the second-largest city in South Dakota, serving over 72,000 residents. Their Water Reclamation Department treats nearly 3.5 billion gallons of wastewater annually.

Aerobic digestion and nitrification-denitrification work together thanks to an innovative membrane system

An outstandingly efficient industrial wastewater treatment plant using technology being introduced to Australasia is demonstrating to the food, beverage, and agribusiness processing industries how to turn waste into profit.

Thermal mass flow meters do a good job of measuring gas flows in water treatment and wastewater treatment applications. Measuring digester gases, which can contain moisture ranging from vapor to droplets, however, makes the job a bit tougher for all gas flow measurement technologies. Identifying the right solutions to deliver accurate, repeatable and reliable readings without having to reengineer the piping system becomes much easier and more economical by following these helpful guidelines.

The Roaring Fork Water & Sanitation District WWTP receives residential activated sludge at an ultimate site capacity of 1 MGD. Prior to the 2009 installation of the Duperon FlexRake Low Flow, the plant had operated with a manually-raked bar screen.

Suspended growth systems, such as activated sludge, are a very common form of secondary wastewater treatment. The potential to optimize and improve the operation of such treatment plants using ATP is tremendous. ATP can directly quantify active biomass, which is key to providing secondary treatment. Two of the many potential uses for ATP in a wastewater treatment plant are aeration and solids optimization and toxicity monitoring and identification.

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

In recent years, various perflorinated chemicals (PFCs) have come under increasing scrutiny due to their presence in the environment, in animals, and in human blood samples. There are two major classes of PFCs: perfluoroalkyl sulfonates such as perfluorooctanesulfonic acid (PFOS) and long chain perfluoroalkyl carboxylates such as perfluorooctanoic acid (PFOA) and perfluorononanoic acid (PFNA).

There are many different joints that can be found on waterworks pipeline components. This paper focuses on the three most common joints.

Different flow meter technologies were used in this geothermal power plant to monitor and measure brine. However, these traditional technologies failed. That’s where Panametrics PT900 Portable Ultrasonic Flowmeter was able to help.

Lack of sufficient straight pipe run made it impossible to successfully apply the preferred magnetic flow meter (magmeter) to accurately measure the flow of raw sewage.

As a result of clean energy mandates and the rising cost of energy, wastewater treatment facilities around the country are retrofitting their instrumentation to run highly efficient, cost-effective, clean facilities. To reduce emissions and produce clean energy, solid wastes are often digested in large digester tanks to reduce the volume of waste (sludge) and produce more biogas, which is then used as fuel in the cogeneration process. However, a clean environment calls for not just clean air and clean energy, but clean water as well.

The NEOSEP® MBR system features Kruger’s uniquely designed K-120C and K-240C flat sheet membrane modules.  The modules offer several innovative design features that enhance ease of installation, operation and maintenance.  This includes an integrated central lifting eye, offering an incredibly well balanced module that makes installation and retrieval a simple and stress-free process.

Read about managing water discharge into a mixed water drainage system, electromagnetic flow measurement of water loads, and automated discharge control by way of a structure with overflow. 

The Littleton/Englewood wastewater treatment plant, Colorado, put in place processes to effectively monitor the levels of ammonia in their wastewater treatment.

Precise pH control is critical in biomanufacturing processes to ensure product quality, consistency, and safety. This application note explores the challenges of pH management across bioprocessing stages and introduces Pulsafeeder’s NextStep pump as a reliable solution for accurate chemical dosing and process stability.
