White Paper: Performance Of Floating Horizontal Aerators In Aerated Lagoons And Oxidation Ditches
1/17/2008
When selecting aeration equipment to use for a specific application, issues to address include reliability, serviceability, capital cost, system appurtenances, and cost of operation and maintenance. Another important consideration is oxygen transfer rate (OTR). Horizontal floating aerators have relatively high transfer rates and have been used successfully in aerated lagoons and oxidation ditches. Using equipment with high OTR values reduces the horsepower input that is required and subsequently lowers capital cost and O&M costs. Mixing of wastewater in lagoons and oxidation ditches is also important to maintain solids in suspension

Is It Time To Reassess Your Industrial Membrane Filtration Infrastructure?
9/21/2021
With infrastructure being such a hot topic these days, it is only fitting that industrial water treatment professionals take a second look at their own infrastructure. Here are some areas where new pressures from the impacts of climate change, population growth, or government regulations can benefit from improved filtration membrane technology approaches.

Grab Sampling vs. Continuous Monitoring: Put The Odds In Your Favor
3/22/2019
With relatively predictable flow patterns, municipal wastewater treatment plants (WWTPs) are conditioned to respond to the ebb and flow of demands with a series of small tweaks. While industrial wastewater processing does not always enjoy the same advantage of predictability, continuous monitoring of processes and wastewater output does offer opportunities for more responsive, more precise control.

'Smart Water' Benefits Without 'Big Data' Intimidation
3/31/2020
For water treatment plants (WTPs) and wastewater treatment plants (WWTPs) pressured to do more with their data despite being pinched by a tight budget and a need to retrain employees, a new strategy can make all the difference. Here is how one such approach makes ‘smart water’ analytics less intimidating and how it has helped one utility make more cost-effective decisions while saving precious time and money.

Making It Work: 174 Hydrants And 280 Valves Installed In 120 Days
3/16/2017
A timeline of 120 days. Construction in the middle of winter, when temperatures were frigid and snow covered the ground. Despite these challenges, Elite Excavating Company of Ohio, Inc., was able to install 174 AMERICAN Flow Control American-Darling MK 73 fire hydrants and 280 resilient wedge gate valves in sizes 6 to 18 inches in three months.

N-Technology Impeller Pumps Eliminate FOG Buildup At Resort And Casino
3/19/2015
The successful addition of new restaurants and clubs at a resort and casino in Upstate NY brought with them a flow of fats, oil and grease (FOG), which gelled into a floating blanket atop the main station’s wet well, where the sewage flows converge from the network of smaller stations throughout the property boundaries.

Taste and Odor Treatment with UV-Oxidation - Mississauga, Ontario (Case Study)
7/7/2010
The Region of Peel is the second-largest Canadian municipality after the city of Toronto, and draws its drinking water from Lake Ontario — the smallest of the five Great Lakes. To meet the projected population increase from 1,160,000 people currently to an estimated 1,571,000 people in 2031, the Region decided to upgrade and expand its water treatment plant. To deal with seasonal taste and odor compounds produced by algae blooms in Lake Ontario, the membrane plant will be equipped with a Trojan UV-Oxidation system.

New Luminescent Technology Brings Faster, More Accurate CBOD Analysis
2/4/2013
Measuring DO in the CBOD procedure was once troublesome and inefficient for lab personnel and operators alike at the Southside Wastewater Treatment Plant in Tyler, Texas. But all that changed when they adopted new luminescent technology that has eliminated problems with instrument drift, slow measurements, and frequent maintenance.

State-Of-The-Art Treatment Equipment Greatly Reduces Plant’s Energy Consumption
3/25/2015
Driven by compliance with more stringent water treatment standards, the Fond du Lac Wastewater Treatment Plant (WWTP) leveraged the upgrade opportunity to improve beyond limiting ammonia effluent levels. The plant improved energy fficiency, reduced maintenance and operating costs, and eliminated bypasses into Lake Winnebago during high rainfall.
