Join us on September 27 at 10 am PT or September 28 at 4 pm CET for The Future of Wastewater Treatment: How nanobubbles improve treatment efficiency and reduce costs
September 12, 2023 (Hawthorne, CA) – Moleaer, the leading nanobubble technology company, hosts two webinars on the benefits of nanobubbles in wastewater treatment. The webinar called “The Future of Wastewater Treatment: How nanobubbles improve treatment efficiency and reduce costs” will be offered for two time zones, September 27 at 10 am PT for North America and September 28 at 4 pm CET for Europe.
The webinars will cover how Water Resource Recovery Facility (WRRF) operators are continuing to be challenged with process problems that previously had no solution until now.
Over the last couple of decades, there have been two major shifts in municipal wastewater characteristics. First, water conservation and low-flow appliances necessitated by water scarcity and drought have concentrated wastewater contaminants over time. Second, the increased use of surfactant-based products like surface cleaners and liquid soaps and detergents, especially after the pandemic, paired with fats, oils, and grease (FOG), interfere with nearly all wastewater treatment processes because they impede solids separation, oxygen transfer, and nutrient removal, and consume disinfection chemicals. These changes in wastewater characteristics have created new operational challenges and have increased the cost-to-treat wastewater.
Surfactants enter wastewater from many sources, including household cleaning products, personal care products, and industrial processes. Surfactants are compounds that have both hydrophilic (water-loving) and hydrophobic (water-hating) parts. When enough surfactants are present, they form micelles, which are aggregates of surfactant molecules with their hydrophobic tails facing inwards and hydrophilic heads facing outwards. Micelles are very stable in water and are difficult to remove using conventional treatment processes.
Micelles are colloidal structures that can trap other organics, such as proteins and fats, oils and grease (FOG). FOG and surfactants combine in wastewater to form a stable emulsion that disrupts wastewater treatment processes leading to inefficiency, operational challenges, process upsets, and increased operating costs. Colloids contribute to the slowly biodegradable fraction of chemical oxygen demand (COD). The slowly biodegradable fraction of COD is the part of COD that is not easily broken down by bacteria. This results in higher effluent biochemical oxygen demand (BOD), COD, TOC, and nutrient levels which poses major challenges to WRRFs and water reuse facilities.
Moleaer’s technology uses air and water to generate in-situ chemistry in the form of nanobubbles that selectively target contaminants that cause inefficiencies and odors in wastewater treatment. Nanobubbles enable process intensification by breaking down slowly biodegradable contaminants like surfactants and FOG to more readily biodegradable compounds, making the wastewater easier to treat.
In this webinar, Andrea White, P.E., Moleaer’s Global Director of Water Process Engineering, will discuss the challenges that surfactants pose to wastewater treatment and how nanobubble treatment addresses these challenges. She will also share data and findings from a number of case studies showing how nanobubbles are being applied to reduce the cost-to-treat wastewater by improving solids removal, effluent water quality, and biogas quality while also reducing process upsets, foam, odors, and energy and chemical demand.

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% and 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.
