In aquaponics and aquaculture, UV disinfection for freshwater aquariums and ornamental ponds is not necessary, but is recommended. The purpose is to protect disinfectant power. Removing all micro-organisms is pointless. Water is recirculated several times. Every time it is processed in the biofilter, it becomes loaded with bacteria. In aquaponics, bacteria also live in plant roots. Il faut en avoir, mais pas trop pour les poissons. It is therefore advisable to thoroughly disinfect the new water supplied to the fish tank. In contrast, partial disinfection is sufficient for the recirculation loop (RAS).
If you’re looking for an effective disinfection system for freshwater aquariums and leisure ponds, our full range of freshwater UV reactors can be consulted online, and design calculations can be carried out on this page.
On the UV reactors for fresh water page, many solutions are proposed (up to a unit flow rate of 130 m3/h). For higher flow rates, up to 130 m3/h, please contact us!
- Select “Freshwater “
- Select the water source to be potabilized, e.g. “Aquariums and freshwater ornamental ponds”.
- 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, we will 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
