Enhanced Aeration for DAF, Clarifiers & MBR

MoleaerTM  Nanobubble Generator

All particles have a “surface charge” when present in water. Just like “surface area”, it is a fundamental parameter that directly impacts the performance characteristics of any suspension, such as surface chemical activity. Surface charge effects are normally negligible for massive solids, but they become dominant in the description of colloidal behavior.

Air bubbles in water are negatively charged. The high concentration of negatively-charged paramagnetic nanobubbles created by the Moleaer generator has two effects on particles suspended in water: (1) it alters the ionic equilibria of any dissolved ionic species in a solution and (2) it changes the net charge on a particle surface. Both directly impact the stability of the particle suspension.

This substantial increase in the interface between air and water provides a much greater contact area for better chemical mixing. It impacts the efficiency of chemical reactions with any dissolved or suspended components in the water and enhances aerobic bacterial activity.

Our Moleaer™ nanobubble generator is an essential complement to any dissolved air flotation clariifer. It produces trillions of microscopic, nano-sized air bubbles that attach themselves to the suspended particles present in water, thus making them extremely buoyant. Given proper water conditioning and suitable fine bubble size, even solids with densities higher than that of water can be raised to the surface of the clarifier.

Most modern dissolved air flotation systems require that a certain portion of claried water be recirculated back through a bubble generator. Moleaer’s nanobubble generator is unique from all other aeration devices because its ability to consistently generate bubbles of proper size with no coarse air bubbles. Once introduced into a DAF clarifier tank, Molear’s nanobubbles rise to the surface at the rate of approximately 8-12 inches per minute, creating a thick float on the water’s surface.
