THE COOLING TOWER AS A BIOREACTOR



Cooling towers are common sights in the vicinity of buildings,factories and even power plants. These cooling towers function as heat transfers units that will throw away the heat to the environment so as to maintain ideal temperatures within the building environments or production processes.

One of the most popular cooling tower model is the water cooled cooling tower. Heat is transferred to the coolant water through heat exchangers and the heated water will be pumped to the cooling towers where the excess heat is loss to the surrounding environment through evaporation of the water

Most of these cooling towers are exposed to the environment and in fact act like bioreactors which can support high growth of various types of microorganisms. These build up of microorganisms are the source of many problems in various industrial processes such as microbial corrosion, loss of heat transfers and clogging of pipes and are even hazardous to our health as linked to the famous Legionella's disease.
