Microbiological Problems in Cooling Water
Algae, fungi, and bacteria cause microbial problems associated with
industrial cooling water systems. They cause plugging, fouling,
corrosion, and destruction of wooden cooling tower components. Many
different bacteria species may exist in cooling water systems. Some of
the problems caused include severe bacterial slimes and fouling,
sulfuric acid, under deposit corrosion and health hazards. They are
adhering to heat transfer surfaces and reduce heat transfer and water
flow.
Warm water in the cooling system is a natural habitat and breeding
grounds for microorganisms. Chemical treatment is required to
eliminate this biological growth. Cooling towers must be thoroughly
cleaned on a periodic basis to minimize bacterial growth. Unclean
cooling towers promote growth of potentially infectious bacteria

Microbial Influenced Corrosion ( MIC)
Microbial Influenced Corrosion (MIC) is a corrosion in which
microorganisms contribute to the corrosion process. The most
serious cases are when their action generates conditions that
start corrosion, which would otherwise not have happened.
Slime-former bacteria, which form slimy coverings over surfaces,
reducing oxygen transport and trapping particles of debris
Sulphate–reducing bacteria, produce hydrogen sulphide from
dissolved sulphate in anaerobic conditions
Sulphur oxidizing bacteria, produce sulphur or sulphuric acid
Iron oxidizing bacteria, oxidize soluble ferrous iron to insoluble
ferric |

BIOFILM
A biofilm is a layer of microorganisms contained in a matrix
(slime layer), which forms on surfaces in contact with water.
Incorporation of pathogens in biofilms can protect the pathogens
from concentrations of biocides that would otherwise kill or
inhibit those organisms freely suspended in water. |
Our Products
ICI-718 –I - They are very effective against aerobic bacteria,
fungi and algae. These are non-oxidizing microbiocide in liquid form,
highly effective against a broad spectrum of microorganisms. It
effectively combats the menace of algae, fungi and bacteria.
ICI-718 –II - Is a broad-spectrum anti-microbial product
designed for use in industrial re-circulating cooling water system.
These are non-oxidizing microbiocide in powder as well as liquid form,
highly effective against a broad spectrum of microorganisms
ICI-718 III -. is an non-oxidizing liquid non-metallic, non-
phenolic formulated for use in industrial cooling system and air
washers system. It prevents growth of Micro-organisms such as fungi,
bacteria, sulphate reducing bacteria and algae in industrial cooling
system.
ICI-718 IV - Is a non-metallic, non phenolic, broad spectrum
biocide effective against bacteria, fungi and algae keeps the cooling
re-circulating water clean.
