Water and wastewater professionals rely on accurate flow measurements for process operation and regulatory compliance. Selecting the best flow meter for each application is essential to obtaining accurate flow data.
Make sure you’ve read the Ultimate DAF System Design Buyer’s Guide Parts 1 & 2 before starting here.
VigorOx® WWT II is an equilibrium peracetic acid solution that contains 15% peracetic acid (PAA) by weight at full concentration. The solution exists as an equilibrium of PAA, hydrogen peroxide, acetic acid and water.
Combined with the installation of the new filter media and wash troughs, this particular type of underdrain and media retainer brought the water treatment plant’s operations up to speed.
In 2004, Headworks Inc. was selected to supply 22 screens to the George W. Kuhn Retention Treatment Basin (“GWK RT Basin”) located in the Detroit Metropolitan Area of Michigan.
In order to meet the demand of growth within the city and to achieve stringent effluent limits, the City of Sanford worked with CPH Engineers to design the Sanford South Water Resource Center (WRC), located in the heart of Central Florida. The facility produces a high quality effluent of reclaimed water standards, which is distributed throughout the region.
Using historical data and Seeq analytical software, Nukon calculates when sewer blockages will occur up to 13 hours before occurrence, preventing spills.
To ensure that aeration equipment will provide not only the best overall solution for their treatment needs but also the lowest total cost of ownership, design engineers and plant operators must take into consideration three primary factors: blower selection, right-sizing, and smart control systems.
At a certain point in the project development process you will have qualified a few dissolved air flotation (DAF) system manufacturers from a field of many. Now you have to decide which one’s DAF System design will best suit your needs. How do you choose?
Water quality laboratories across the nation are faced with both a rising level of water quality awareness amongst the general public, as well as rising costs in water quality monitoring. As a result, laboratories are looking for more efficient ways to provide higher quality monitoring.
Dosing of the precipitant was adjusted manually based on the laboratory measurement value of the daily composite sample and so was unable to respond to possible peaks. Although being compliant with the effluent limits, the values observed fluctuate between 0.2 and 0.8 mg/L.
As interest in biogas grows, more attention is being paid to measuring biogas flow, which has long been a problem area in process measuring technology.
Almost all wastewater collection system odor and corrosion problems are a result of the formation of sulfide. Sulfide is formed under the anaerobic conditions that typically exist in wastewater force mains.
The QuEChERS (Quick-Easy-Cheap-Effective-Rugged-Safe) sample extraction method was developed for the determination of pesticide residues in agricultural commodities.
Biochemical Oxygen Demand (BOD) analysis is the test everyone loves to hate—and for compelling reasons.
With time, labor, and money at a premium, state-of-the-art controls on filtration equipment can ease the burden on operators while improving uptime and lowering costs.
There are several accepted methodologies for testing stormwater treatment devices in the lab, but what works best? A comparison study gets us closer to the goal of optimal sediment removal efficiency.
These robots aren’t taking jobs — they’re simply making the job of utility workers safer and easier.
When it comes to answering questions about whether the oil and gas industry’s wastewater can be safely reused for other purposes, like food crops, livestock, or even drinking water, there are a number of other serious factors to be considered.
After the Supreme Court, in its 2006 Rapanos v. United States decision, admonished the U.S. EPA and Army Corps of Engineers to once and for all come up with an acceptable definition of “waters of the United States,” which is the linchpin for all regulation under the Clean Water Act, the agencies, nine years later, finalized regulations redefining that term in their 2015 Rule.
Based on wastewater properties, various types of mineral buildup can affect wastewater treatment plant (WWTP) piping. With their impacts on plant energy efficiency and potential restriction of throughput capacity, keeping pipes free-flowing is an important aspect of WWTP operations. Here’s guidance for coping with two common problems associated with phosphorus concentrations in wastewater — struvite and vivianite.
