Cooling is an indispensable part of many industrial processes. An industrial cooling tower is the heart of any industrial process that necessitates cooling as a course of action. Cooling towers are used to cool water in large volumes. These are specialized heat exchangers where water and air are brought into contact so as to bring the water’s temperature down. 

Although cooling towers help to make a plant’s indoor environment cooler, if left untreated, these can become home to various harmful types of bacteria like Legionella and may also become susceptible to scaling, organic growth, and corrosion. This will not only mean unhygienic conditions for the workers but may also lead to reduced plant productivity and the need for expensive equipment replacements down the road. This is when you may need the help of specialists. Branded companies like Merus can help you fix any problem with the cooling tower, so your industry can keep running safely and efficiently.Β 

But how exactly does the cooling tower water treatment system works and what does it control? Let’s find out.

Cooling Tower Water Treatment

Treatment for a cooling tower includes an arrangement of technologies that work to eliminate all the damaging impurities from the feed water, circulation water as well as blowdown. It can help control and regulate alkalinity, hardness, iron, organic matter, silica, sulfates, TDS and TSS.

What and how these technologies are employed to treat a cooling tower depend on many different things, including 

  • Type of cooling tower (open or closed loop)
  • Quality of the feed water
  • Chemistry of the circulatory water
  • Recommended quality requirements for the cooling tower

How does it work?

Based on the above and other parameters, a treatment system for your cooling tower may include the given steps –

Cooling tower makeup water intake

It may not be always needed depending on the water quality, but when needed, the technology used removes silica and hardness and the pH level of water is stabilized.  

Filtration and ultrafiltration

In this step, the cooling tower water is filtered to remove the suspended particles. 

Ion exchange

Ion exchange resin refers to a softening process. It is suitable for makeup water that contains dissolved salts. The process removes magnesium and calcium ions while replacing

them with sodium ions. The advantage of sodium ions is that they form highly soluble salts, which don’t precipitate and hence don’t cause scaling.

Chemical addition

Different chemicals to neutralize the acidity of water, checking the growth of microbes, scale inhibitors etc are added to further treat the water. 

Side-stream filtration

A side-stream filter is any filter that is used to clean a portion of the water in a cooling tower. A side-stream filter is used to filter a portion of the water continuously. This principle behind this technique is that the constant removal of particles keeps the system clean.

Blowdown treatment

When water evaporates from the cooling tower, the dissolved solids like silica, calcium, chloride, magnesium,  etc persist in the water that is recirculating. The concentration of these dissolved solids keeps increasing as more water evaporates. Too high concentration leads to the formation of scales and may also cause corrosion problems. The problem is solved by replacing the concentrated water with fresh makeup water. 


For an industry to keep running efficiently, it is important that due inspection of each of the component is carried out on a regular basis. Proper treatment of cooling tower water system is very important for both the safety of the workers and the manufacturing process to keep running smoothly. But you should only trust experts in the field so that no compromise of any kind is done.

Cortana for Xbox One Finally Released: Your Personal Gaming Assistant

Lucky summers for Xbox One users as they will be getting one of the much-awaited updates from Microsoft, the Cortana is about to be rolled out.
For those who have no idea what Cortana is, well, it is a Microsoft’s virtual assistant which lets you communicate with your device like "Siri" on Apple iOS and "Google Now Assistant" for Android. You can talk to your device by saying “Hey Cortana” and you can then give all the instructions through voice.

The purpose of launching Cortana is to integrate Windows 10 and the Xbox console. Though initially the update will not be available for Windows 10 but at a later stage, you will be able to use it with Xbox app on Windows 10.

Xbox Cortana

What to Expect

So how Cortana will change your gaming experience? How can it be of any help? Is it really a much needed feature?

Cortana is referred to as the ‘personal gaming assistant’. It will assist you in gaming, of course, but this is just the beginning. Right now, you will be able to use Cortana for gaming features only but in near future, it will work with other devices and will include a whole lot of other exciting features.

Cortana lets you communicate with your console over voice. It can let you find new games, turn on the Xbox, you can start a party, and you can perform several other tasks. You can also use it to search stuff on Bing, simply give a voice instruction to search something and voila, you are done.

The good news is that there are multiple updates that will be rolled out so you will see some nice changes this summer, for example, a new game collection will be rolled out, improvements in screenshot sharing feature, some of the famous PC games will be added to your Xbox live, and much more.

This is just the beginning. Microsoft is very enthusiastic about the update and it has already announced that Cortana is not limited to gaming only, so you should expect some good new features being added in recent times.

When and Where

Microsoft will be rolling the updates in phases – not all at once, thus you have to exhibit some patience. The first update will be rolled out this summer. You will get two updates this summer and more updates will follow soon.

At this moment, the Cortana will be available to Preview testers only. No, not to all the Preview testers but only those located in the US, UK, Spain, Germany, Italy and France. If you are in one of these countries, consider yourself lucky as you will be among the first ones who will have the privilege to try the new update.

Keep your fingers crossed for the update and let’s hope that the update proves to be good for the gamers. The basic purpose behind the launch of the Cortana and these updates is to integrate Xbox One fully with Windows app (the PC). Once it is done, you will experience gaming of another level.
But that’s not going to happen right away.

For now, just sit back, relax and let Microsoft do all the hard work. Wait for the update to reach you.
