UV disinfection system applied to dechloramination

In swimming pools, chlorine is used to disinfect the water. However, when added to water, it attacks the organic matter it contains, and generates chloramines.

The problem with water with a high chloramine content is the reactions it causes: irritation of the eyes, skin and mucous membranes of swimmers. And the smell of chlorine can also lead to respiratory infections.

Unlike most people think, a strong odor does not mean that the water is disinfected and sanitized. UV-C reactors are used to dechlorinate and disinfect aquatic and public facilities:

public pools
communal spas
chlorine-treated thalassotherapy pools
chlorine-treated spa pools

Dechloramination treatment counteracts the microbiological risks (from pathogenic micro-organisms) that can be a source of disease. Treatment with chlorine-based products is the most widely used, but has the disadvantage of not controlling the risk of certain parasites that can lead to water quality problems. Only UV treatment can provide ideal disinfection and optimal dechloramination, so that the water remains safe for swimmers.

If you’d like to equip yourself with an efficient dechloramination system, the full range of UV reactors for Water for Human Consumption / Sterilization can be consulted online, and design can be carried out on this page.

Disinfection system benefits

In addition, producing healthy water, without any risk of contamination by microorganisms, UV water treatment is also part of an environmental approach:

For your health, water treatment without the addition of harmful pool products guarantees allergy- and respiratory-risk-free swimming (non-chemical).
It also provides additional value for the environment, ensuring crystal-clear, odor-free water.
The absence of chlorine makes for a safe, environmentally-friendly process.
UV treatment represents cost savings, thanks to extended plant lifetimes and simple, reliable, long-lasting equipment.
Last but not least, the system can be installed and maintained quickly and easily.

Design tips: UV disinfection applied to seawater

On the page dedicated to UV reactors for water for human consumption / Sterilization, we offer a wide range of solutions (up to a unit flow rate of 130 m3/h). For higher flow rates, up to 130 m3/h, please contact us!

Select ” Drinking water / Sterilization “.
Select the water source to be potabilized, e.g. “Dechloramination”.
Enter the flow rate to be treated (for example 25 m3/h)
Adjust the cost of electricity in your country (for example 0.09€ for France; 0.23€ for Germany)
Let 30 mJ / cm² (or adapt)
Specify the temperature of the water (normally, between 5 and 40°c is sufficient)
Please enter your email address so that we can send you the design right away.

In any case, to ensure optimal disinfection and to determine whether prefilters are necessary, it is recommended that a source water analysis be performed with these parameters:

Iron
Hardness
Turbidity
Manganese
Suspended solids (TSS)
UV Transmittance
