UV disinfection system for seawater disinfection

The most effective way to disinfect water is to use a UV system to disinfect seawater with ultraviolet (UV) light, where 254 nm of UV deactivates the DNA of microorganisms.

We need to protect marine life from a whole range of diseases, including :

bacteria
mushrooms
virus
protozoa

If an infection occurs, the fish and other marine species could perish, and the aquarium would suffer considerable financial losses.

To protect marine life, seawater must be disinfected. Water should subsequently be monitored to ensure that the following parameters remain stable:

chemical balance
pH
temperatures remain stable

In this way, we protect the lives, health and comfort of the ecosystem’s inhabitants.

If you’d like to acquire an efficient activated carbon dechlorination system, our full range of UV reactors for corrosive/salty water can be consulted online, and design calculations 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 corrosive/salty water, you’ll find 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 “Corrosive / salty water”.
Select the water source to be treated, e.g. “UV systems for seawater disinfection”.
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
