Water disinfection

Many homes in Cyprus store water in roof tanks or underground tanks before it enters the property. Warm temperatures, stagnant water and biofilm inside tanks or pipework can increase the risk of microbiological contamination if the system is not properly maintained.

Filtration removes physical contaminants such as sand, rust and suspended particles. Water disinfection targets bacteria, viruses and other microorganisms. For complete water treatment, filtration and disinfection are often used together.

The most common residential solutions are UV water sterilizers and chlorine dioxide dosing systems. UV disinfects water as it passes through the reactor, while chlorine dioxide provides residual protection throughout storage tanks and pipework.

Neither system is universally better because they solve different problems. UV provides instant chemical-free disinfection but leaves no residual protection. Chlorine dioxide continues protecting the water inside tanks and pipes. The best choice depends on your water source and plumbing system.

Water disinfection helps reduce microbiological risks, but overall drinking water quality also depends on dissolved minerals, chlorine, taste and other contaminants. Many homes combine disinfection with reverse osmosis or activated carbon filtration for drinking water.

In many cases, yes. A water filter removes physical contaminants, but it may not eliminate microorganisms. If your home uses storage tanks or there is a risk of bacterial contamination, a dedicated disinfection system may still be recommended.

Yes. Many professional water treatment systems combine UV sterilization with chlorine dioxide dosing. UV provides immediate disinfection, while chlorine dioxide helps prevent bacterial regrowth and biofilm formation throughout the plumbing system.
