Water quality is especially important in recirculating aquaculture systems (RAS). Yet despite extensive mechanical and biological filtration, pollutants can accumulate over time, originating from, e.g., undigested feed, fish faeces, or other fish residues like skin or mucus.

ASPERIX® A&F hydrogen peroxide is an effective tool for improved water hygiene in RAS. It helps to decrease the level of pollutants through oxidation to a stable minimum. ASPERIX® A&F can be dosed manually or automatically via pipes and pumps into the water loop of the aquaculture system, such as in a side stream, before the filtration systems or the protein skimmer.

In water, the hydrogen peroxide oxidates the pollutants, resulting in smaller organic oxidation products such as aldehydes, carboxylic acids, etc, which can be more easily digested by the biological filters of the RAS. The hydrogen peroxide itself catalytically decomposes into oxygen and water only.

VIGOROX® Trident is a peracetic acid solution for recirculating aquaculture systems (RAS), pond systems, and egg hatcheries. EPA-registered VIGOROX® Trident can be dosed directly into the tank. It is a highly effective biocide capable of treating a wide range of pathogens that can occur in RAS and on processing equipment.

After use, peracetic acid rapidly breaks down to water, oxygen, and acetic acid, thus requiring no additional steps to clean up any chemical residues.
