Foaming can happen due to (i) Physical and chemical environment, and (ii) Key micro-organisms.
The physical and chemical environment includes gas bubbles, pH and temperature or surfactants.
Key micro-organisms include microthix parvicella, gordonia amarae, etc.
Foaming can be controlled by applying suitable chemicals meant for the process of neutralising them.
There are many suitable methods of getting rid from Foaming.
