Blower Rentals Offer Tailored Solution To Temporary Needs
10/27/2019
There are many reasons for a utility to rent a blower for wastewater aeration. Besides the obvious — an emergency — plant operators may need a rental to bridge the gap during upgrade projects, supply seasonal need to supplement air, or perform testing.

A Modular, Energy-Saving Approach To Wastewater Gaining Traction
10/22/2019
A combination of urban sprawl, more stringent environmental regulations, and aging facilities is putting a huge strain on the wastewater operations at many municipalities. The good news is that membrane aerated biofilm reactor technology, also known as MABR, offers a compact and energy-efficient solution.

A Fresh Take On Biological Wastewater Treatment
10/18/2019
Improving wastewater treatment efficiency requires some type of change in the physics, biology, or economics of the process. In this Water Talk interview, Jeff Kelly, Red Valve’s senior product manager for the Tideflex Aeration and Mixing System, describes how to change all three — to the tune of a cost-saving 50-percent reduction in applied airflow! The Tideflex approach uses a unique diffuser design to support on/off aeration and mixing cycles without clogging. Managed by oxidation-reduction potential (ORP) readings, the novel technique supports a biological selection process that encourages the exclusive growth of facultative anaerobes — the most resilient wastewater microbes, which get rid of phosphates and nitrates without producing hydrogen sulfide.

New Technology Stretches Wastewater Infrastructure
10/17/2019
Population growth, stricter regulations, and increased energy costs continue to exert significant pressure on municipal wastewater operations. But rather than investing in tired, old solutions such as the construction of additional concrete tanks, water system managers are seeking new ways to stretch the limits of their infrastructure.

Three Largest Challenges With Wastewater Lagoons
11/1/2016
When it comes to wastewater lagoons, there are three main challenges that operators run into. The first, similar to other parts of the nation’s wastewater treatment infrastructure, is age. The second is compliance with new EPA ammonia, nitrogen and phosphorus limits which many lagoon plants weren’t designed to deal with. And the third is expansion as communities grow and need additional capacity.

Energy Efficiency Boosted By Replacing Controls Not Blowers
10/29/2015
At the wastewater treatment facility, the biggest energy consumer is almost always the multistage aeration blowers. Replacing these blowers with high speed turbo blowers can save energy but the short-term cost to replace the existing blowers, reroute pipe and set new foundations can make the change a hard sell.

The Right Technology To Fit Your Needs
10/29/2014
Aerzen supplies blowers for industrial and for wastewater treatment. Tom McCurdy, Regional Sales Manager at Aerzen, told Water Online radio in an interview that his company is unique in that they have the ability to help customers pick the right technology for the application without bias because they have multiple technologies available. They will work with the customer within what they need in terms of maximum and minimum flows, pressure swings, on-off cycles, etc., and will help guide a customer towards the right technology.

Introducing The O-Factor In Aeration
10/29/2014
There is no one-size-fits-all solution when it comes to aerating wastewater lagoons. As Randy Chann, President and CEO of Environmental Dynamics International (EDI) explains in this Water Online Radio interview, each lagoon environment needs to be configured to meet both financial and regulatory outcomes.
