H
anovia’s new PureLine UV range provides chemical-free treatment and water disinfection for the food, beverage and brewing sector (Fig. 1). Joining the PharmaLine
and SwimLine ranges, the PureLine is the latest industry-specific UV system from Hanovia designed to make product selection as easy as possible. All that’s needed to choose the correct model is the application and the required flow - the appropriate model is then simply selected from the appropriate datasheet. Hanovia will have already specified the necessary dose, chamber geometry, lamp type, surface finish, seal materials and connections that are typically required by that application. Special designs can also be supplied for users who have unusual requirements.
Disinfection of water Standard PureLine models are available for the disinfection of water, syrups, brines and for the
de-ozonation of process water (designated D, S, B and DO respectively), with the range being supplemented by the PureLine PQ. Ensuring biosecurity of water systems, the
performance qualified PureLine PQ is tested and approved by independent experts to the requirements of the USEPA UV disinfection guidance Manual (UVDGM). Benefiting from full flow bioassays conducted by independent engineers across a wide range of operating and water quality conditions, the PureLine PQ guarantees 99.999 per cent disinfection at its maximum bioassayed dose.
UV transmittance monitor Providing proven, constantly displayed and verified disinfection, PureLine PQ is equipped with a calibrated absolute intensity UV monitor and controller, which automatically corrects the dose calculation as UV transmittance varies, without requiring an external UV transmittance monitor. This provides the user with an accurate and instant
