Odor Control

Most offensive odors produced in wastewater are the gaseous byproduct of decomposed organic matter. The most common of these is hydrogen sulfide, commonly referred to by its chemical formula H2S, which is formed from the anaerobic degradation of organic matter containing sulfur or from mineral sulfates and sulfites. Hydrogen sulfide is known for its rotten egg smell and can adversely impact human health at levels above 10 ppm. Odor in sewer lines, collection points, treatment plants, and ponds can lead to public complaints and reduces aesthetic value. One means of treating odors, including H2S, is to prevent the water from going anaerobic by increasing dissolved oxygen (DO) or oxidation reduction potential (ORP) using air, oxygen or other oxidants. Moleaer's effective gas-injection technology delivers a high volume of air or oxygen nanobubbles, efficiently maintaining DO and preventing the anaerobic conditions that lead to odorous compound formation.

Efficient Aeration

A Moleaer nanobubble generator produces over one billion nanobubbles, each smaller than the wavelength of light, per milliliter of water. The sheer volume of bubbles, coupled with neutral buoyancy and high surface tension, results in industry-leading oxygen transfer of greater than 90%, efficiently increasing DO and ORP and oxidizing H2S and other odor-causing compounds.

Odor Prevention

Nanobubbles produced by the Moleaer system are neutrally buoyant, meaning they do not float to the surface of the water and rupture. They instead disperse following Brownian motion, distributing evenly throughout the body of water, regardless of water column depth. Upon achieving DO saturation, the remaining nanobubbles introduced to the body of water will remain in suspension creating a DO buffer. When DO is consumed in the water and an oxygen gradient is present, the nanobubbles in solution dissolve additional oxygen into the body of water, maintaining a steady-state DO concentration and preventing the formation of more H2S.

Energy Efficiency through Existing Pumping

Moleaer nanobubble generators operate as inline gas injection systems meaning as water flows through the generator, gas is injected in the form of a nanobubble. Moleaer's systems are available with or without a pump. When supplied as the latter, customers can attach Moleaer's nanobubble generators to the discharge end of a pump as long as the existing pump can accommodate a 12 psi (0.75 Bar) pressure drop and still maintain necessary flow. When capable of adding the nanobubble generator to distribution pumps such as those found in pump stations and force mains, Moleaer's nanobubble generators provide the most energy efficiency aeration solution on the market and can start to treat H2S and even BOD upstream of the treatment plant at a fraction of the energy of conventional aeration solutions.
