Mixing Comparison: Hydraulic Or Gas

Fairfield-Suisun Sewer District (FSSD) in California installed a Vaughan Rotamix hydraulic mixing system next to an identical anaerobic digester with a 7-year-old gas mixing system.

What Private Utilities Need to Know About Nutrient Loading and Eutrophication

For private utilities, discharging wastewater isn’t a one-size-fits-all process. If your facility serves a resort, a golf course, a residential community, or a mixed-use development, you’re likely discharging into smaller, localized water bodies (creeks, ponds, wetlands), not large rivers or oceans. And while these ecosystems are beautiful they’re also incredibly vulnerable to nutrient loading and eutrophication.

Winery Receives Green Certification With TITAN MBR

This prominent Napa County vineyard and winery received a prestigious green certification after committing to sustainable and environmentally-friendly technologies, including the installation of a dynamic MBR wastewater treatment system.

How The Industry Can Take On Wipes In The Waste Stream – And Win: Part 3

As outlined in earlier articles, increasing public awareness or even seeking legal action are potential tools to help municipalities gain control of the wipes problem. However, many agencies have seen that these strategies are not completely effective in the long term, and they must also employ new technologies to permanently deal with the wipes epidemic.

Comparing Benefits Of V-Cone® And Coriolis Meters

Proper operation of water treatment processes depends on accurate flow measurements. Also, flow data is often required by regulatory agencies.

Key West Resort Utilities Maximizes Reuse And Nutrient Recovery

Water scarcity poses unique challenges to KW Resort Utilities Corp. (KWRU), the utility firm that provides wastewater management, wastewater recovery, and wastewater treatment in the region. KWRU began operation in the late 1960s and has worked hard over the decades to keep up with wastewater needs as population and tourism have boomed, spurred by land reclamation and development. 

Energy And Resource Recovery: Generating Resources, Not Waste Streams

“Sludge-to-energy” is trending in wastewater treatment, but what technologies have the most potential?

What's Missing From Your Water-Monitoring Strategy?

When it comes to water quality monitoring, professionals in municipal, industrial, and agricultural applications might have distinctly different concerns about what they measure, but they all share a common concern about the cost and ease of obtaining that data. Fortunately, a new alternative for achieving water quality data and analytics with a high degree of autonomy, accuracy, and affordability is now available to all of them.

Pre-Filtration Is Essential To Protect Your Membranes

Any Reverse Osmosis System is only as good as the Pre-filtration System protecting it.  Pre-filtration is no place to scrimp when it comes to sizing, quality, efficiency and performance. 

Decoding Ozone Disinfection Revisited

Late last year we published an extremely popular article on understanding the ozone disinfection process. Based on the response, we’ve updated this year’s article with a bit more information to illustrate how powerful these simple tools can be to operations staff.

What Are You Doing To My Pipe: Can PVC Pipe Be Loaded?

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.

Pile Cloth Media Filtration For Clean Utilities

Cooling towers and boilers consume the most fresh water in the industry, with industrial process waters carrying the balance. Power plants and refineries use more water volume for the cooling process than any other area of the facility. Mining and food and beverage industries consume higher volumes for their processes. Clean water may come from a range of sources, including clarified surface waters, groundwater or properly treated wastewater (reuse) sources.

Determination Of Polycyclic Aromatic Hydrocarbons In Seafood

Polycyclic Aromatic Hydrocarbons (PAHs) are a large group of organic compounds found naturally in the environment. PAHs are monitored by the US Environmental Protection Agency due to their carcinogenic characteristics.

A Comparative Study Of On-Line And Laboratory TOC Analyzers For Analysis Of Municipal Wastewater

This application note presents comparative data obtained on influent and effluent wastewater samples using laboratory and on-line TOC analyzers employing the heated sodium persulfate oxidation technique in USEPA-approved methods 415.3 and SM 5310C.

Comparison Of Ultra Low Range Total Chlorine Residual Limits Of Detection And Quantitation Across The Water Industry

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.

Automatic Rinse Tank Controls

Proper rinsing is one of the most important steps in quality manufacturing or metal finishing. Plenty of low cost, good quality water for rinsing has been available in the past, so rinse water conservation has been largely ignored.

Removal Of PFCs With Activated Carbon

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).

Application Note: Preliminary Performance Study On An On-Line TOC Analyzer In Pharmaceutical Applications Total Organic Carbon (TOC) analysis is an effective technique for detecting and measuring the presence of organic contaminants in waters used throughout industrial processes, municipal water uses, and for determining residual concentrations of organic material on the surfaces of equipment used in the manufacture of active pharmaceutical ingredients.
