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.

Protecting Water Treatment Technologies

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.

The Best, Cleanest Dechlorination Technology

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.

Technology Comparison

  High Dose UV System Activated Carbon Filter Sodium Metabisulphite
Dechlorination Effectiveness Good Good Good
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
Footprint Low High Medium

Why Choose UV…

  • ACF provides a breeding ground for bacteria and requires regular heat or chemical sanitisation to maintain microbial control.
  • ACF needs media replacement, incurring significant cost.
  • SMB requires regular chemical handling and introduces a higher loading onto the downstream RO membranes
  • Both ACF and SMB have a significant footprint occupying valuable factory space, which may be particularly important for skid mounted equipment.
