Hanovia’s Medium pressure UV lamp technology delivers a guaranteed high UV dose for effective dechlorination and enhanced disinfection, perfect for many Pharmaceutical manufacturing applications. In addition, UV dechlorination protects RO membranes and ion-exchange technologies from residual chlorine and risk of bio-fouling.
Hanovia’s UV Dechlorination systems provide a clean, efficient alternative to other Dechlorination methods for the protection of the key water treatment technologies such as Reverse Osmosis and Deionisation. Hygienic applications such as Pharmaceutical and Cosmetics manufacturing desire clean water treatment technologies which have minimal bacteria build-up, low system down-time and optimised running costs.
Hanovia UV dechlorination systems reduce free chlorine in process lines to levels below the requirement for RO and DI / EDI.
Hanovia UV dechlorination provides distinct advantages over traditional technologies such as Activated Carbon Filtration (ACF) and Sodium Metabisulphite dosing (SMB) which although proven chlorine removal technologies are prone to potential microbial contamination, require significantly more operator involvement and plant-room space leading to higher lifetime costs.
|High Dose UV System||Activated Carbon Filter||Sodium Metabisulphite|
|Bacterial Contamination||Zero – High dose UV kills micro-organisms||High Risk – high surface area nutrient source||Possible growth of sulphur metabolizing bacteria|
|Chemical Addition||Zero – Chemical-Free||Zero – Chemical-free||Yes – increases load on downstream technologies|
|Water Consumption||Zero||High – Frequent backwashing and Sanitisation||Low – Chemical tank make-up, CIP|
|Impact on RO membranes||Zero – Bio-fouling significantly reduced||High – Significant bio-fouling, increases particulate loading||Medium – increased chemical loading|
|Continuous Operation||Yes||Weekly down-time for back-washing, frequent SIP||Yes – as long as chemical tank is replenished|
|Maintenance Impact||Low – Infrequent lamp replacement||6 monthly media replacement||Daily checks on chemical levels|
