Hozelock Ultra violet clarifiers (UVC) Vorton from Hozelock

Ultra violet clarifiers (UVC) prevent ponds from going green or murky brown or greenish resulting from suspended green or brown pond algae. Algae bloom prolifically especially in warm sunny conditions (summer is always the worst time for algae growing in ponds.)

Hozelock ultra violet clarifiers have the brand name "Vorton".

The flow of the water through the Vorton Ultra Violet light unit (UVC) has been designed so that there is maximum exposure to the UV light.

Ultra Violet Clarifiers ... exceptionally effective Vorton Ultra Violet Clarifiers cause algae to clump together into groups too large to float. They then pass through the system to be removed by the biological filter foams. The Vortron is best used with a biofilter. Biological Filters like the Hozelock Cyprio Ecocel and Green Machine Biological Filters serve two main purposes. Firstly they act as a mechanical strainer for debris and clumps of algae, removing these from the pond. Secondly they create a home for millions of beneficial bacteria which digest pollutants as the water passes over them. The biological filter contains media of very high surface area to create a habitat for very high concentrations of bacteria.

The Hozelock Trinamic (picture below) is the latest pond filter system to use Vortron UVC technology.

As you can see in the diagram open cell foam is one part of the system used to ensure no solids enter the biological chamber. At times this may need replacing and foam replacement sets are available.
