The RESILIO project has helped Amsterdam repurpose rooftops as smart blue-green roofs to reuse rainwater and prevent localized flooding. This project, along with other sustainable water initiatives like the Amsterdam Rainproof program, continues to position the Netherlands at the forefront of water management.

Much of the progress on wastewater effluent quality under the Clean Water Act has focused on centralized facilities in larger cities. Now, decentralized systems are expanding options for municipalities, developers, and engineers to support high-quality wastewater treatment in locales that can’t sustain conventional septic systems or make it too costly to build or access centralized wastewater treatment plant (WWTP) or water reuse facilities.

In municipal or industrial wastewater treatment applications, steel constructed tanks up to 5.0 million gallons per day (MGD) and below offer significant advantages over concrete; benefits that lead to lower operating and lifetime costs, regardless of application.

Godwin’s Dri-Prime 16-in. pump ran a sewer bypass system continuously for a month without issues while the city of Raleigh, North Carolina, replaced a major outfall line feeding its wastewater treatment plant.

What if wastewater treatment plants (WWTPs) could get the expanded capacity, capabilities, and wear resistance of a brand-new bar screen and raking system without going out to bid?

Design routines and operation strategies for activated sludge aeration systems have traditionally been based on manual control. By Robert Smith, P.E., BCEE, Ph.D., YSI

Read about how advanced oxidation processes can offer exceptional benefits in preventing contaminants from leaching into groundwater and surface water. 

In response to Hurricane Harvey, the Fort Bend, TX Levee District No. 2 embarked on a major upgrade project to increase the flow and capacity of one of its pump stations by 400%. The goal of the project was to protect the area around the district from 100- year floods in the future.

When the Kearney, MO wastewater treatment plant began plans to upgrade its headworks they choose JWC Environmental’s Brushless Finescreen Monster to replace its old coarse screen.

A single operational oil and gas refinery produces millions of gallons of contaminated wastewater a year, leading to environmental pollution concerns. Ion exchange resins are a metal- and ion-removal solution to help clean this wastewater for plant reuse or safe disposal. This application guide explains how resins can be used to demineralize refinery water in process, boiler, and cooling water applications.

UV AOP performance verification requires a robust test matrix covering design, operating, and control conditions. This process includes on-site execution, sample analysis, and troubleshooting to achieve successful regulatory approval.

Providing the best value to wastewater customers requires a team of operators that have a deep sense of ownership and are committed to continuous improvement. Such is the case for the operating staff at one wastewater treatment plant whose progressive attitude and a philosophy of “do it right” led them to an investment in online instrumentation and SCADA for compliance, monitoring, and control.

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.

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.

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).

Facility administrators will find the advanced ST100 Series Thermal Mass Air/Gas Flow Meter from Fluid Components International (FCI) helps them improve the accuracy of specialty gas point of use and sub-metering operations to achieve accurate billing in their labs for better cost tracking and control.

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.

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.

The argument has been used that PVC pipe is delicate and can’t be subjected to any kind of loading. In EBAA's years of testing we have found that is not the case at all. PVC can take an extreme amount of strain.
