There have been a lot of research studies on micro bubbles in recent years.
Micro bubbles are miniature gas bubbles of less than 50 microns diameter in water. The micro bubbles, which mostly contain oxygen or air, can remain suspended in the water for an extended period. Gradually, the gas within the micro bubbles dissolves into the water and the bubbles disappear. These bubbles are generated by various types of aerators now available in the market.
These micro bubbles, being of extremely small size, are characterized by having electrical charges. They attract suspended floating particles very effectively. This particular property has been used in sludge treatment by using the micro bubbles to capture and float organic matters, thus decreasing the time required for the sludge treatment.
Micro bubbles have also been introduced by the Japanese to market safe and good tasting oysters. Micro bubbles of concentrated oxygen containing about 2% ozone can be used to inactivate norovirus in shellfish and oysters. This norovirus is one of the major pathogens causing food poisoning in winter. This is a much more cost effective method compared to cultivating the...
