UV DISINFECTION FOR RECIRCULATING AQUACULTURE SYSTEMS (RAS)

With water resources becoming increasingly polluted and scarce, delivering large quantities of high-quality seafood presents a major global challenge.

This has resulted in a shift towards more controlled environments which Recirculating Aquaculture Systems (RAS) offers. However, there are a lot of factors to address in order to achieve success in this complex environment.

Making reared species thrive requires advanced disease control due to continuous water re-use concerning accumulation of species droppings as well as the nutrients used in its feed. If not properly handled, RAS can be an ideal breeding ground for various bacteria and viruses, potentially contaminating the entire production resulting in huge financial losses.

Implementing UV disinfection is a vital integration of a well-functioning and cost-efficient RAS. UV disinfection ensures comprehensive water biosecurity which reduces any virus or bacteria outbreak significantly. As no chemical by-products are added, the crucial water qualities such as pH and temperature remain unaltered, while causing massive improvements in the water turbidity.

The ULTRAAQUA UV systems have been designed to meet the disinfection requirements for even the most complex RAS and disinfects over 100.000 m3/h of RAS water globally per hour.

The great diversity in the product range makes ULTRAAQUA able to accommodate almost any RAS requirements for a high variety of climates and flows in both open channel and closed vessel systems, available in both stainless-steel and polypropylene materials. The best available solution is just a few steps away, whether it may be influent, effluent, or process water to be installed or retrofitted in a variety of RAS layouts.
