2 No Chance for Harmful Microorganisms Cytosi ne Cytosi ne light -light inactivates micro-organisms by damaging the hereditary DNA/RNA, thereby hindering vital cell division processes. Dimer Safe disinfection at 254 nm disinfection has been proven worldwide as the most important water disinfection process. Bacteria, viruses, yeast and parasites (for example, cryptosporidium and giardia) are effectively inactivated by using light. There is no development of resistance in disinfection as is increasingly experienced in, for example, treatment using antibiotics and also in chlorination. There are no resultant dangerous by-products (DBP) as is the case with chemical disinfection. X-rays Ultraviolet Visible light Infrared Vacuum- -C - -A B Spektrotherm lamp (254 nm) Inactivation of microorganisms Wavelength (nm) is a high-energy light with a wavelength of -nm. The -C spectrum with a wavelength of approx. 2 nm to 2 nm is particularly effective for disinfection. Legionella pneumophila WEDECO protects against these extremely resistant bacteria without creating any harmful biproducts Comparison of, chlorine and chlorine dioxide disinfection processes Type Use in Pathogen Virus Cryptosporidium Possible harmful organically burdened bacteria by-products waters (Humic substances) disinfection with low pressure none Chlorine THM, AOX, Chlorite Chlorine dioxide Chlorite (THM) ++ = very effective + = effective = less effective - = barely effective -- = not applicable

4 WEDECO Spektrotherm Lamps The most advantageous solution when compared to medium pressure lamps LOW PRESSURE MEDIUM PRESSURE EIGENSCHAFTEN VORTEILE Significantly higher efficiency in -C: Spektrotherm Lamp: % efficient Medium pressure lamp: % efficient Lower electricity and operating costs Essential higher electricity and operating costs Fewer lamps Shorter lifespan of lamps Lower lamp operating temperature: Medium pressure lamp: C Spektrotherm Lamp: C Medium pressure requires cooling at zero-flow Low lamp aging and longer service life Medium pressure requires reactor reduce operating costs temperature monitoring Significantly less scaling on the Medium pressure lamps require a protective quartz sleeves mechanical wiping system Immediate re-start possible Medium pressure lamps must cool down for minutes Amount of liquid mercury: Amount of liquid mercury: Spektrotherm lamp: mg Medium pressure lamp: up to 3 mg Environmentally-friendly Spektrotherm lamps are recycled by WEDECO free of charge Emission spectra [wavelengths in nm] Relative emission (%) nm Spectral curve of cell inactivation DNA absorbtion (%) Relative emission (%) Spectral curve of cell inactivation DNA absorbtion (%) The WEDECO Spektrotherm lamp emits almost entirely at a wavelength of 254nm, which lies in the maximum spectrum range for effective disinfection The medium pressure lamp emits a broad-brand spectrum that for the most part lies outside the spectrum range relevant to disinfection 169% Taking photo reactivation into account = safe disinfection % % % % 2% % WEDECO Spektron Medium Pressure Energy costs Maintenance Lamp costs / Quarz tube costs Investment costs Photo reactivation, meaning the self-repair of inactivated microorganisms, can occur with many microorganisms making it particularly important to consider this effect in the original equipment design. This is done by choosing a safe dosage ( J/m 2 =mj/cm 2 =. µws/cm 2 ) that is confirmed by microbiological tests (according to DVGW W-294 and/or Ö-Norm M ). Leading specialists have repeatedly ascertained that there is no difference in the safety of the disinfection capabilities between low and medium pressure lamps when this dose is applied. Lifespan cost analysis based on years.

5 Disinfection Systems Spektron Series The biodosimetrically tested systems from the Spektron product range meet all the requirements of safe and environmentally friendly water disinfection according to 11 of the German drinking water regulation (TrinkwV 21). The Spektron units are certified according to Austrian ÖNORM (M ) and German DVGW (W 294-2) directives. An European-wide CEN standard is in preparation. The new Spektron range offers a wide array of uses from domestic water supply to industrial uses to large water plants with a capacity of more than one thousand m 3 /h. What makes them special is their consistent optimisation of hydraulic characteristics with the use of the unique CrossMix module. Electronic ballasts of the newest generation in conjunction with our Spektrotherm lamp technology allows minimising energy and lamp costs by up to 3%. Improved Spektrotherm lamps offer today even better efficiency and a very long lamp life. The robust construction makes them certifiably usable in waters with high humic contents or in environments with increased requirements in terms of EMC protection. The new uv reactor construction ensures simple installation within virtually any space limitation. ADVANTAGES Safe disinfection through biodosimetrically certified systems No harmful by-products (such as THM s in chlorinating) Exceptionally low operating costs through uniquely efficient electricity flow and electronic units of the newest generation Excellent EMC protection, exceeds valid industry and household standards Ongoing self-monitoring of intensity, reactor temperatures and water flow combined with a high-performance memory and analysis system Extremely low loss of pressure Variable installation positions for easy integration into existing pipeline systems
