6. Filter type and size Filter: BOLLFILTER SELFCLEAN 6.18.2 PN10 BWT Filter candles: 30µ wire mesh

7. Why 30µ mesh and double filtration? Tests have shown us less is not enough! We started with 40µ mesh and single filtration and tested at DHI. We failed! Problem relates to ”soft” organisms above 50 my: rotifers in fresh water and polychates in brackish water DESMI Ocean Guard is the only UV based system, that have passed IMO testing in fresh water Alternatives: High concentrations of chemicals Very large UV dosage which requires lots of energy

13. Landbased tests: IMO: 2 x 5 tests in two of three salinities (fresh, brackish, salt) USCG: 5 tests in each salinity for which the system shall be approved Controlled environment tests, with many requirements to inlet water: IMO and USCG system approval requirements Salinity <3 PSU (Fresh) 3-32 PSU (Brackish) >32 PSU (Salt) Additions Dissolved Organic carbon (DOC)> 5 mg/L > 1 mg/LLignin sulphonate Particulate Organic Carbon (POC)> 5 mg/L > 1 mg/LCorn starch (Maizena) Total Suspended Solids (TSS)> 50 mg/L > 1 mg/LKaolin clay UV-T (%) in DK, 1 cm - NO REQUIREMENT! 27-4941-6180-87(Lignin sulphonate) ParameterInletTreated Organisms ≥ 50 µm> 10 5 / m 3 < 10/m 3 10 ≤ Organism size ≤ 50 µm> 10 3 / mL< 10/ml Heterotrophic bacteria> 10 4 / mL< 1 or 100 or 250 CFU/100ml depending on type

15. Test conditions Biological tests

16. Hot topics UV-Transmission Efficiency of UV treatment is depending on the UV-Transmission (UV-T) of the treated water So far a completely neglected issue, no IMO requirements or guidelines exist Several established test facilities can not provide test water with UV-T below ~60% Water in several major harbors has UV-T below 50% Our OXYCLEAN system has passed test in freshwater with UV-T as low as 38% UV lamp UV Intensity, % Distance, cm0123 0 100 UV lamp UV Intensity, % Distance, cm0123 0 100 UV-T = 0,90 (90% of light remains after penetrating 1 cm into water) UV-T = 0,50 (50% of light remains after penetrating 1 cm into water)

18. Several major ports are located at river estuaries: Brackish and fresh water conditions will be met and it is essential to have a BWTS that can deal with “soft” organisms and water with low UV-T resh / brackish water ShanghaiBremerhavenRotterdam

21. IMO type approval issued by Lloyd’s Register on behalf of Danish Maritime Administration, Nov. 2012 Lloyd’s Register type approval issued in February 2013 ABS “Product Design Assesssment” certificate issued in January 2013 DNV “Safety Assessment” concluded in January 2013 OxyClean TM system approvals
