Aeration & Blowers Podcasts

  1. Blower Rentals Offer Tailored Solution To Temporary Needs

    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.

  2. A Modular, Energy-Saving Approach To Wastewater Gaining Traction

    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.

  3. A Fresh Take On Biological Wastewater Treatment

    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.

  4. New Technology Stretches Wastewater Infrastructure

    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.

  5. A Cost-Effective Approach To Aeration Optimization

    The need for water utilities to update aging infrastructure and meet emerging challenges has reached a critical point across the country, but investing in solutions typically costs more than most municipalities can afford. The good news is that advanced aeration technology is available to optimize existing infrastructure at lower costs than major modifications or new construction.

  6. Three Largest Challenges With Wastewater Lagoons

    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.

  7. Enhanced Primary Treatment Reduces Energy By Separating BOD Before Aeration

    At WEFTEC 2016, Evoqua Water Technologies explored six core challenges faced by wastewater treatment plants -- energy reduction, nutrient removal, odor and corrosion control, aging plant equipment, water reuse and disinfection. In this Water Online Radio interview, Paul Rice, Municipal Marketing Director with Evoqua Water Technologies, discusses energy reduction and nutrient removal in more detail.

  8. Energy Efficiency Boosted By Replacing Controls Not Blowers

    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.

  9. Reduce Costs With Energy And Equipment Savings

    For more than 60 years, Philadelphia Mixing Solutions Limited has been providing customers with a full range of globally proven in-tank mixing solutions.

  10. Instrumentation In The New Era

    Measuring dissolved oxygen (DO) in the aeration process has gone from a helpful, if vague, step for information gathering to a precise imperative for increased efficiency and reduced costs.
