Hampton Roads Sanitation District was created in 1940 to reduce pollution in the Chesapeake Bay. It currently serves a population of approximately 1.6 million with nine regional wastewater treatment plants in Hampton Roads and four smaller plants on Virginia’s Middle Peninsula. HRSD set the goal to reuse its treated wastewater for nonpotable purposes in the 1980s. An oil refinery located next to their York River Treatment Plant approached HRSD in 1996 to supply reclaimed water for the refinery’s cooling and process water. Previously, the refinery utilized increasingly expensive potable water and upgrading its own treatment facilities was too large an investment. In December 2000, HRSD signed a 20-year agreement to provide the refinery with 0.5 MGD of reclaimed water

Wastewater treatment plants are tasked with removing contaminants from water before it’s safely released back into the environment. With the complexity and volume of wastewater treatment, traditional monitoring methods can be slow and labor-intensive. However, fluorometers are transforming how these plants operate by providing rapid, real-time measurements of water quality.

After Hurricane Katrina, the Army Corps of Engineers moved quickly to fast-track a multi-billion-dollar infrastructure project to shore up the Southeast Louisiana Flood Protection System – a project that had been stalled for decades. As part of this effort, Pentair was commissioned to build 11 massive pumps to be installed along the Gulf Intracoastal Waterway (GIWW) just south of New Orleans.

The City of Shelby, Ohio recently upgraded its activated-sludge wastewater treatment plant to double its capacity to 5 MGD, while expanding its capability to treat and disinfect combined high-volume stormwater and wastewater flows generated by wet-weather conditions.

The Moab Water Reclamation Facility (WRF) was initially constructed in the late 1950’s to provide primary treatment of domestic wastewater for the Moab area. However, the plant could no longer keep up with the higher flows and loading due to population growth and rising tourism. In addition, with aging infrastructure and the new permit cycle in sight, upgrades to the biological treatment were necessary to ensure full compliance. Read the full case study to learn more.

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.

An automotive parts manufacturing plant was using a polymeric membrane to remove oil from water it used to rinse parts. The rinse water contained between 6% and 7% oil and the customer wanted to remove >95% of the oil from the water so the water could be reused in the plant.

Memosens technology converts the measured value to a digital signal and transfers it inductively to the transmitter. With signal alarms in the event of transmission disruption, Memosens offers safe data transfer for increased availability of the measuring point and trouble-free processes. With Memosens 2.0, measuring points become completely future-proof and ready for IIoT.

Achieving consistent water pressure is a challenge for geographical areas that have grown faster than the development of infrastructures to accommodate water demand and for businesses such as fast food restaurants and strip malls.

Increasing water scarcity, which results in higher water costs, is pushing manufacturers to reclaim and reuse their wastewater. 

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.

A new pipe-repair solution promises to save time and money, while also being sustainable, long-lasting, fully scalable, and safe for workers.

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.

The analysis of Total Organic Carbon (TOC) in seawater can be both challenging and expensive. The concentration of organic carbon in seawater is of considerable interest. The effect this matrix can have on TOC analyzers can lead to rapid consumable turnover, costly maintenance and repairs.

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.

Read about the cloth media filter installations that have been operating in food and beverage wastewater plants for over 25 years.

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.

Levels of phosphorus, a chemical element that promotes organic growth, must be controlled in wastewater coming from beverage, food and dairy processing plants. Failure to control phosphorus accurately has a negative impact on water quality and can lead to large fines.

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 Saalfeld-Rudolfstadt Association in Germany must rely on cutting-edge technologies that optimize flow measurement in order to allow for smooth processes and supply 82,000 inhabitants with clean drinking water.
