Microbiological Control Strategy used in Cooling Tower Systems
Posted: May 26, 2020
Since vaporization cooling tower systems are usually left open to the airspace and sunlight, they are liable to microbiological activity and the resulting adverse effects. Pathogenic microbes like Legionella pneumophila can lead to health risks. Slime formed by the repeatedly happening gram-negative sort of organisms can result in absolute heat exchanger fouling and the loss of cooling prescription.
The biofilm too can also give rise to microbiologically impacted attrition together with acute localized metal deprivation. The single or dual-cellular organism called algae, as well as fungal mats, can block water flow, trigger an unsightly appearance, in addition to damaging wood and tower structures.
Ideal quality makeup water like municipally supplied water for drinking or well water should possess negligible microbes as well as nutrients to support biological growth. For the cooling towers, though, they absorb floating dust and bacterium. If you ant to learn more information about this, then please visit https://www.saracoolingtower.com/
The dust holds nutrients that brace the broadening of microorganisms. If there is less contamination, the level of activity becomes self-restraining and easy to manage.
The location of the cooling tower in addition to the processes near the cooling tower can highly affect the propensity for microbiological activity. For instance, food plants can produce a lot of organic compounds for the bacteria to achieve more growth.
Oils that contaminate a cooling tower stimulate high microbiological growth. Process contaminations or the utilization of secondary waste-waters for makeup to the cooling towers prepare the environment for microbiological growth.How you can prevent algae in cooling systems
When the weather conditions are hot, many facility managers tend to use their cooling towers every day. Cooling tower systems are a fantastic way to make your buildings comfortable. However, these cooling towers need to be maintained by cleaning and disinfecting them more often to put a stop to algae and biofouling growth. Continued algae growth is dangerous for cooling tower systems as it contributes to Legionella growth. Meanwhile, legionella is defined as the bacteria that causes a fatal illness called Legionnaire’s disease.
The algae growth can damage the proper function of your cooling system in addition to blocking screens, disrupting water flow, and hiking your cooling expenses. You can prevent algae from accumulating in your cooling tower system by practicing the following;
- Regularly clean your cooling towers while following your manufacturer’s directions.
- Formulate and follow an operative water management strategy that will specify when your cooling tower may need added cleaning. Your strategy may entail scrutinizing the cooling water more often and check for alerting signs of algae, sediment, and biofilm.
- Utilize chemicals to block algae growth and destroy existing algae. Some chemicals like chlorine may get utilized in limited quantities for long timeframes as a preventive strategy. Other chemicals that kill algae can be applied in shots to get rid of disturbing algae starting to form. Several chemical types are available for you to choose based on the water alkalinity or acidity, their similarity with one another, together with your particular cooling tower.
No exact solution exists for blocking algae in your cooling tower system. Most probably you will need several ways to prevent algae. This is so because even a limited algae amount can grow quickly and uncontrollably, increasing health challenges and production efficiency problems
Make use of your water management professionals to formulate an algae prevention plan. Devise an algae prevention strategy in your water management plan.Choosing your ideal chemicals for your cooling tower
Want to know your right chemical formula? Begin with conducting laboratory analysis of your water. The analysis should be done by a water treatment professional and may include information regarding your water system performance, areas you need to tackle, the kind of algae you intend to prevent, and other factors affecting your facility.
After conducting this analysis, your water treatment expert should properly outline your chemical requirements as well as form a customized formula that will rectify your challenges and make your water systems run like how they were designed to do. This will help you implement the correct quantity and type of chemicals that will maintain the safety and efficiency of your cooling tower system.Conclusion
It is crucial to keep your cooling tower from algae as well as biofouling growth to keep its proper functionality and also limit the spread of fatal diseases amongst all stakeholders.
