Difficulty With Accurate Testing For BOD In Industrial Stormwater Runoff

Biochemical oxygen demand (BOD) is a measure of the amount of dissolved oxygen used by microorganisms to break down organic material in a sample of water. Because BOD is not one specific pollutant, it can be difficult to characterize the nature of BOD, identify the source in stormwater runoff, and select the appropriate treatment approach to reduce BOD in stormwater runoff and discharge. The most effective way to minimize BOD concentrations in stormwater discharges will be to minimize the exposure of stormwater to materials that are a source of BOD.

What is PFAS?

PFOA (perfluorooctanic acid) and PFOS (perflurooctane sulfonate) are organic synthetic chemicals that have been used in manufacturing a multitude of industrial and consumer-based products including coatings, carpeting, and fire-fighting foams. Over several decades, they have contaminated the environment, specifically our drinking water sources, causing significant health concerns that recently prompted the EPA to take action.

What is Activated Carbon?

Although the term granular activated carbon is used generically, it can refer to dozens of similar – but not identical- adsorbents. Depending on raw material, method and degree of activation and other factors, activated carbons can perform differently in various applications.

Evaluating the Advantages of Decentralized Membrane Bioreactor (MBR) Wastewater Treatment

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.

Capitalizing on Evolving PFAS Removal Options

Granular activated carbon (GAC) and ion exchange (IX) resin have long histories in removing a variety of per- and polyfluoroalkyl substances (PFAS), known as ‘forever chemicals.’ But choosing optimal treatment vessel and media efficiency depends on the specifics of the application. Here are some performance considerations of evolving options that can pay dividends for first-time and experienced PFAS removal operators alike.

Navigating the Carbon Exchange Landscape

Granular activated carbon (GAC) filters are an increasingly popular technology for removing contaminants from liquid or vapor-state water. To remain effective, carbon media must be replaced periodically. The best way to handle spent carbon depends on a variety of factors, including the application, contaminants adsorbed, local regulations, staff expertise, and more.

How To Make Stormwater Compliance Accessible

For most businesses, managing stormwater falls well outside their area of expertise. Keeping up with changing rules and regulations can be overwhelming, not to mention the challenge of taking samples, testing for contaminants, and determining whether one is in or out of compliance.
