DNV approves DESMI UV water treatment

The company says this is a ‘significant advancement’ in the aquaculture industry which will bring greater transparency and trust in UV treatment technologies.

The approval was awarded on 16 February and is said to be notable as it moves beyond the traditional certification provided by the Norwegian Veterinarian Institute, which verifies UV doses of at least 25 mJ/cm2.

With many aquaculture operations requiring higher UV doses, typically ranging from 70 to 200 mJ/cm2, this latest validation will provide greater credibility and assurance, says DESMI.

Historically, the aquaculture sector has grappled with a lack of clarity and consistency regarding the actual UV doses delivered by different systems, the company continues, pointing out that the NVI’s certification focuses on lower UV doses and leaves a gap in validating higher, more effective UV doses.

DESMI’s breakthrough with DNV validation ‘addresses this critical issue head-on’, it says.

The scope of the validation encompasses all of DESMI’s aquaculture UV treatment systems under the product lines Aquashield and Aquadose. It includes various water qualities, from turbid to clear, and accommodates a broad range of flow rates.
