The surface inside a cooling tower or evaporative condenser framework must be maintained from the perspective of cleanliness. Maintaining cooling towers is a tedious undertaking, but is well performed by cooling tower manufacturers in India. Be that as it may, you need to clean the towers to guarantee enhanced thermal execution and to renounce the development of biofilm and disease-causing microbes, including Legionella.

Cooling tower manufacturers consistently provide appropriate instructions and suggestions about cleaning and upkeep of the cooling towers to their clients. It is recommended that to ensure the proper functioning of cooling towers, they ought to be cleaned and sanitized once per year. On the off chance that the bacterial development is high, cleaning ought to be performed all the more regularly. Even though cleaning of cooling tower is certifiably not a substitute for water treatment, yet it is a piece of the whole program for viable bacteriological control.

Managers of societies and facilities are confronting the colossal obligation of safekeeping cooling towers during the COVID-19 pandemic. It incorporates alleviating and keeping the cooling towers away from the damage of soil, microbes, and other probable threats. In some cases, the Covid’s effect on ventilation, heating, and cooling (HVAC) systems is yet to be investigated, however, cooling towers are one of the most likable places for the development of microbes, for example, Legionella pneumophila.

Troubles Due To Biofouling

Cooling tower manufacturers believe that microbiological fouling in cooling systems is the aftereffect of the development of algae, bacteria, and other microorganisms on surfaces. Once the water systems are opened, it causes dampness, leading to bacterial growth, however, fouling issues ordinarily grow all the more rapidly and are more prone to develop in open recycling systems.

The basic requirement for algae to grow includes three things namely, dampness, daylight, and supplements. Cooling towers allow the outside air, so they permit outside organisms (supplements for algae growth) and daylight into the water. In such cases, the growth of algae exceeds limits, if left unchecked.

Cooling water streams contain low levels of nutrients fundamental for microbial development, so development is generally slow. Open recycling cooling water systems grasp organisms from the air and, through evaporation, pack supplements present in water. There is no single answer for forestalling bacterial growth in a cooling tower. Odds are, you’ll need a multi-layered methodology that centers around being proactive in forestalling bacteria and algae, instead of working on it once in a lifetime.

Most cooling tower suppliers believe that. even a modest quantity of algae can rapidly outgrow, setting you up for heath threats and issues on efficiency, we referenced previously. Thus, microorganism development is rapid. If your cooling water systems leak, there is a higher chance for bacteria to grow. Reuse of wastewater for cooling adds supplements and contributes a lot of microorganisms to the cooling water system.

Notwithstanding the accessibility of natural and inorganic supplements, factors like temperature, pH control range, and nonstop air circulation of the cooling water add to a climate that is ideal for microbial development. Daylight vital for the development of algae may likewise be a concern. Accordingly, huge chunks of microbial populaces develop.

Steps To Maintain Cooling Towers

The result of uncontrolled microbial development on surfaces brings out slime arrangement. The combination of organic and non-biological materials creates slime. The natural segment, known as the biofilm, comprises microbial cells and their faces. An extracellular polymeric substance (EPS), is a combination of hydrated polymers. These polymers structure into a gel-like formation around the cells and appear to attach to surfaces. The non-biological parts can be natural or inorganic garbage from numerous sources which have gotten adsorbed or inserted in the biofilm polymer.

Inspection Of Cooling Towers

Monthly inspection of cooling towers can keep diseases at bay. Regular inspections will all the more help determine the best time to schedule cleaning.


Bacterial growth mostly takes place around the tower fill. Legionella prefers hiding in the deposits of the tower fill. Descaling will clean the fills and prevent further growth.


Bacteria find cooling towers to be a habitable area for breeding. Disinfectants reduce the nutrient availability for microbes as such, they find it hard to dwell.

Tower Basin Cleaning

Cooling tower basins should always be cleaned once sediments are visible. There are cooling tower vacuums available today that make it easy to remove any sediment from the basin.

In view of creating the perfect world, make use of a good water supervisory team to avoid any bacterial/algae growth. On the off chance that you don’t have your water supervisory team set up yet, starts here. You can also take the help of a cooling tower manufacturer to figure out a plan that works best to keep away microbes from infesting the cooling system.
