Controller provides traceability for UV
procedures
A pharmaceutical manufacturer has reduced costs by installing control systems providing data-logging facilities, giving full traceability, for ultraviolet water disinfection procedures.
Pharmaceutical manufacturer GSK has reduced operating costs at one of its UK production facilities by installing Photon control systems for its Hanovia ultraviolet (UV) water disinfection units According to the company's Fine Chemicals Engineering Manager: "Since installing the Photon controllers our engineers only have to change the lamps in the UV disinfection units when the dose falls below a pre-determined level, rather than arbitrarily every 13 weeks, as they did before

UV water disinfection knocks out the bugs
One of the UK's leading convenience food manufacturers has invested in two UV water disinfection systems to permanently kill bacteria, viruses and moulds.
This brings with it both cost and efficiency benefits." Providing data-logging facilities which ensure full traceability of all disinfection procedures, the microprocessor-driven Photon systems monitor all significant disinfection parameters at once, including UV dose, UV intensity and lamp hours-run.
At the facility, raw water from the towns mains supply is filtered and treated with UV before entering the primary circulation loop storage tank.
This feeds the purified water ring main (secondary loop), which is also treated with UV.
The units are continuous-running, except during the nightly sanitisation, and treat a maximum water flow of 0.75m3/hour.
UV works by penetrating the cell walls of microorganisms and destroying their DNA.
It has a kill rate greater that 99.99% and is effective against all known microorganisms including bacteria, viruses, fungi and their spores.
Hanovia UV systems also remove chemical contaminants in the water by photolysis.
