Anybody who works with cooling towers knows that the only way to ensure its efficiency would be to keep it clean and free of contaminants. This is a huge task because the main purpose of a cooling tower is to scrub air free of airborne pollutants. This means that after some time, build up will occur that can either slow or completely halt the operations of a cooling tower.
Luckily, there are many available solutions in the market and here we will explore one of the most popular options today, specifically cooling tower side stream filtration.
What is it?
The idea behind a cooling tower's side stream filtration is to keep a certain volume of water going through the filter. This ensures that all water gets circulated at least once every few hours. Build up of microbes and other contaminants are greatly reduced, increasing longevity and efficiency of the cooling tower.
Do you need it?
This system can set a company back given its high initial price. Although its main selling point is it will pay for itself after a certain amount of use, it can still be tough to convince the higher-ups that such a system is necessary.
Sometimes, the situation simply calls for it. You will need a side stream filter if your water source is high in solids. River, ground, and repurposed water are some examples of water sources with solid pollutants. The filters are necessary if your biocide is not performing well, which means microbial growth is out of control.
What can it do?
Side stream filters have a wide array of benefits on its own, but to maximise its effects, it’s often paired with a good chemical treatment program. The filters remove any suspended solids while a secondary treatment cleans it chemically. Combined, they often reach a highly cleaned output.
Side stream filters can be an expensive option but with its long list of advantages, it’s not surprising why it is still popular.
