GREEN ICEBERG > WASTE WATER TREATMENT

Wastewater Treatment


 

The UFB system is a method of injecting oxygen into the water so as to enhance the biological treatment process, reduce off-gassing and lower treatment costs. A highly efficient, proprietary 2-phase gasification process saturates wastewater with dissolved oxygen and trillions of ~100nm-sized nanobubbles that provide a latent transfer of oxygen for days after the point of aeration.

 

Ultra Fine Bubbles exhibit unique characteristics; due to their minute size and high internal pressure, they can remain stable in water for prolonged periods of time. Unlike microbubbles that rise and burst quickly on the surface, nanobubbles have minimal buoyancy and can disperse throughout a body of water due to the principals of Brownian motion. The longevity of the UFB in water, combined with a larger interfacial surface area, significantly increases their oxygen transfer capacity well beyond traditional aeration systems.

 

UFB can be injected at any depth and oxygenate the entire column of water including the bottom sludge layer that requires oxygen to support aerobic breakdown and conversion of nutrient.

 

Our UFB generators have the potential to provide the lowest OPEX aeration solution. As opposed to traditional aeration which relies on large HP blowers with diffusers or surface aerators to transfer oxygen into wastewater, our UFB generators can be installed in-line utilizing existing pumps to inject UFB into passing water, or they can operate with their own dedicated pumps. In-line use means existing aeration systems can increase oxygen delivery without additional energy consumption. Traditional aerators consume considerable amounts of energy yet their oxygen transfer efficiency is very low. They also generate turbulent and fast-rising bubbles that strip unwanted gases from wastewater and inhibit optimal aerobic digestion. UFB injection method creates a low turbulent, oxygen-rich environment which enables aerobic bacteria to function more efficiently.

 

Our UFB generators can be installed quickly with minimal retrofitting, meaning there is no disruption to daily operations. They have a proven track record of reliability, are rated for 10+ years of continuous operations, and require minimal maintenance. The units are self-cleaning and do not foul or plug-like traditional diffusers. They are mounted on the outside of a tank or on the bank of a lagoon, thus giving operators easy access and control of the unit. The generators can alternate between air and high purity oxygen depending on the given oxygen demand of the treatment system, and they can also be turned on and off to conserve energy when required.
