Moleaer Exhibits And Presents At WEFTEC On Lowering The Cost Of Wastewater Treatment With Nanobubble Technology

Join Moleaer on October 1-4 in Chicago, Illinois at McCormick Place, Booth 8400

Moleaer, the leader in nanobubble technology, will be exhibiting at WEFTEC, the industry’s largest trade and educational conference, this October. John Crisman, the company’s Senior Water Process Engineer, will present on the ways “Clean Chemistry Lowers the Cost-to-Treat by Improving Wastewater Treatability and Increasing Capacity: A Case Study on Nanobubble Pretreatment.” The presentation is on October 3 at 4:00 p.m., as part of the Design Tools and Technologies for Preliminary and Primary Treatment professional education track.

WEFTEC is held from September 30 to October 4 this year, offering more than 150 wastewater educational sessions, and showcasing more than 800 industry-leading product, service and technology providers in the main exhibition hall. Industries represented will include wastewater treatment, design and modeling, drinking water, and water reuse and reclamation.

Moleaer’s October 3 presentation will focus on how nanobubble pretreatment is enabling municipal water resource recovery facilities (WRRF) to improve treatment efficiency and process intensification, by removing inhibitory compounds commonly found in influent streams. These compounds consist of fats, oils and grease (FOG) and surfactants, which disrupt wastewater treatment by coating the surface of water, bubbles, solids and biomass. This impedes oxygen transfer, interferes with separation, inhibits biological processes like nitrification, and increases chemical demand, making commonly applied wastewater treatment processes inherently inefficient and more costly than necessary.

Preliminary and primary treatment process design may not be as exciting as advanced biological process design, but without effective preliminary/primary treatment systems, advanced downstream processes are doomed to fail. Far from traditional methods, innovative and far more effective approaches have recently been developed. Some technologies—like that from Moleaer—don’t require design changes and can be easily and cost-effectively integrated with existing processes.

The education track will present three technologies or design approaches that improve significantly on traditional outcomes. Case studies of the technologies will be presented, highlighting lessons learned.

In his session, Crisman will share process and data specifics from California’s Goleta Sanitary District case study using Moleaer’s technology, allowing the WRRF to:

  • significantly reduce odors, foam and septicity
  • increase secondary treatment process intensification by 20%
  • increase primary clarifier solids removal by 10%
  • reduce aeration energy power draw by 43%, and
  • reduce chlorine consumption by 44%.

By the track’s end, attendees will be able to recognize innovative approaches to designing preliminary and primary treatment processes, identify potential benefits of these new methods, and apply the lessons learned from presented case studies.

Moleaer will also offer two free, live webinars the week preceding WEFTEC, for those who wish to explore the applications and economics of nanobubble pretreatment. Webinars entitled “The Future of Wastewater Treatment: How nanobubbles improve treatment efficiency and reduce costs,” will be held on September 27 at 10 a.m. Pacific Daylight Time, and on September 28 at 4 p.m. Central European Time.

Crisman and Andrea White, Moleaer’s Global Director of Water Process Engineering, will share the nature of new challenges facing WRRFs today, and how Moleaer’s unique technology can help overcome them, using only air and water.

About Moleaer
Moleaer is the global leader in nanobubble technology with a mission to do more using less water. By deploying the power of nanobubbles, the company enhances and improves the performance and productivity of many of the world’s most critical industrial processes. Its proprietary nanobubble technology unlocks the power of water to help farmers grow more food, empowers businesses to manage water more effectively and efficiently, and restores aquatic ecosystems sustainably without chemicals.

Moleaer has deployed more than 2,400 nanobubble generator installations in more than 52 countries. The generators inject nanobubbles ― 2,500 times smaller than a grain of salt ― that supersaturate the water with oxygen or other gases, form mild oxidants for disinfection, and increase water’s ability to permeate soil and rock. Moleaer’s patented nanobubble technology provides the highest oxygen transfer rate in the industry at >85%. It is a cost-effective, chemical-free solution, proven to increase sustainable food production through better plant health and heat tolerance, reduce the use of chemicals across water-based industrial processes including the food value chain, restore aquatic ecosystems, and improve natural resource recovery.
