In late 2005, the City of Newberg, Oregon, decided to upgrade their water treatment plant disinfection process from gas chlorine to on-site hypochlorite generation (OSHG) in an effort to simplify operations and increase operator safety. The plant produced an average of 2.5 million gallons per day (MGD), with a peak capacity of 5 MGD.

The Pottstown, Pennsylvania Wastewater Treatment Plant handles the wastewater generated by 15,000 area homes, commercial businesses, and industrial sites located in the borough of Pottstown and three nearby townships. The facility is rated for 15.6 mgd and treats an average flow of 7 million gallons of sewage a day.

Henderson, Louisiana is located directly in the center of what is commonly considered ‘Cajun Country.’ Right next door to Breaux Bridge, the town that is known as ‘The Crawfish Capital of the World’; our claim to fame is dealing with the crowds and traffic of that festival every spring. By Ray Robin

An internally fed rotary screen with wedgewire drum featuring 0.020” screen slot openings is applied to screen 900 GPM of brewery wastewater and remove spent hops while letting yeast pass through to reach the anaerobic digester.

Whether addressing sanitary sewer overflows (SSOs), combined sewer overflows (CSOs), or storm sewer systems, the idea of advanced strategic insight is key to minimizing damage or public health risks caused by overflow events. Here is a look at how concentrating on the most at-risk areas first — with a focus on overflow prevention — can offer better control for wastewater utilities of all sizes, as it is doing for the city of Houston, TX.

Municipal, commercial, and industrial water users all face a common issue — how to monitor the quality of the water they use, dispose of, or distribute in a timely, cost-effective manner.

Most mixer manufacturers will say that newer-model equipment is generally more energy-efficient than older-model equipment. The question remains, however, just how much more efficient is the new equipment?

One of the United States’ newest dairy processing plants features advanced wastewater treatment technology that not only radically improves biomass recovery and effluent quality, but also harnesses green energy from waste streams to drive production processes and reduce its carbon footprint.

Comminution technology has been evolving quite rapidly in response to the increasing burden entrained solids have placed on treatment facilities. More advanced devices have been developed in rapid succession. The result has been an exciting and fluid race between the leading manufacturers to develop the best size reduction device. The latest grinder innovations to be introduced have coupled the power of twin shaft grinding with higher flow capabilities and screw screening systems. Here’s a rundown on the past and present state of the art in wastewater solids reduction.

Wanting to avoid an island-wide water system shutdown during peak season, the Village of Bald Head Island turned to the Insta-Valve 250 for help.

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

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 Wet Gas MASSter sensor is for use in applications that have a high level of moisture or condensation present in the gas flow stream that cannot otherwise be removed.

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.

Stockholm water company produces biogas from their wastewater facility which feeds Scandinavian Biogas for energy production. As they need to accurately meter what they sell to the energy facility they used a project contractor firm to engineer and define the best solution for the project.

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).

The textile industry is a water consumption intensive industry. Water is utilized for cleaning the raw material, and for the different steps in the textile dyeing process. Due to the effects of water scarcity and stricter environmental regulations, the cost of fresh water utilization has increased worldwide.
