A 100-year-old beginning It was exactly 100 years ago that the US Navy asked Alfa Laval to develop a centrifugal oil-cleaning separator, which was delivered in 1917. Pioneer in BWTS since 2003 Experience, 1 300 systems sold Long term commitment Global organization
TREATING WATER
Treating water MAIN PARAMETERS THAT EFFECT TREATMENT SALINITY For chemical systems this is a limiting factor UV systems are independent of salinity FRESH WATER (low salinity) Can be challenging for all types of technologies TEMPERATURE For chemical systems this is a limiting factor Medium pressure UV systems are independent of the BW temp. Low pressure UV systems are often dependent on the BW temp. UV-T Chemical systems are not influenced by UV-T Main parameter for UV systems
Treating water UV-T *UV-T stands for UV transmittance and is the ratio of the light entering the water to that exiting the water. For UV systems, UV-T is the most important parameter indicating the efficiency of the system to treat poor quality water and at lowest possible power consumption.

LEGISLATIONS IMO U.S. Coast Guard
USCG status on MPN method The use of an MPN-based method to evaluate mixed assemblages of organisms in ballast water is going to be validated by Environmental Protection Agency s Environmental Technology Verification (ETV) technical panel. United states have commented in official paper PPR4/7 to IMO that A version of the MPN-Dilution-Culture Motility Method is currently undergoing a review within the Environmental Technology Verification (ETV) Program in the United States. This verification assessment will evaluate the method through trials in multiple locations. If the panel finds an MPN method to be acceptable, USCG will have to make a policy decision or rulemaking to incorporate the EPA approved method. It should be noted that MEPC 70 agreed to that viable organisms mean organisms that have the ability to successfully generate new individuals in order to reproduce the species. The MPN method is designed to mesures organisms ability to generate new individuals. The MPN method is undergoing a serious evaluation and it is likely that it will be approved
PureBallast USCG TAC version easily upgraded before expiry of AMS/Extension, if MPN is not accepted IMO IMO & US BW Discharge Software update USCG Type approval plate Update of manual
PureBallast 3.1 No limitation in salinity or temperature Tested and approved in all three water qualities: Fresh water Brackish water Marine water Same hardware and power consumption as current IMO version 3 days hold-time applied to be able to comply with CMFDA/FDA stain method UVI limit of 530-820 W/m 2 for half respective full flow Approved to be installed in hazardous zones at both foreign and US flagged vessels
Why is UVI stated on the USCG TA certificate and not UVT? Also the IMO version has limit on UVI but corresponding UVT was stated on certificate nothing new Poor correlation between UVI and UVT Up to 10 percentage points difference Biological efficiency correlates better to UVI The system measures UVI not UVT Only measured parameters can be used for control of the system The system reduce the flow rate if UVI is low to maintain the UV dose CFD calculations is the base for UVI regulation This have been verified by testing at different flow rates and UVI Impossible to compare UVI values between different manufacturers Hard to compare systems based on UVI/UVT performance only
PureBallast compliance with revised G8 PureBallast 3 is compatible with the revised G8 testing guidelines! Revised G8 requirement (extract) PureBallast Capability 1. A BWMS that has not been tested at all the temperatures and salinities; limits should be defined on TAC cover sheet 2. The System Design Limitations should be specified on the Type Approval Certificate in a table that identifies each water quality and operational parameter together with the validated low and/or high parameter values 3. The shipboard test unit should be of a capacity that allows for further validation of the mathematical modelling and/or calculations for scaling, and preferably selected at the upper limit 4. Viable organisms mean organisms that have the ability to successfully generate new individuals in order to reproduce the species. 5. At least two test cycles in each salinity should be conducted in order to evaluate compliance with the D-2 standard at the minimum holding time specified by the BWMS manufacturer. 6. The range of operational flow rates that a BWMS is expected to achieve in service, at the maximum and minimum operational flow rates 1. No temperature or salinity limitations. Tested in all three salinities under challenging conditions. Successfully tested at 3.4-23 C 2. PureBallast has been tested down to UVT of 42% in all salinities at full flow, which is market leading 3. Tests already conducted accordingly. The largest 1000 m3/h reactor was used to verify biological and operational performance during shipboard testing 4. PureBallast has a technology leading performance when evaluated with MPN method. MPN measures ability to reproduce according to IMO definition 5. Tests at minimum hold time are scheduled to be commenced in March 2017 (Old G8 required 5 days). Those are the only additional tests needed 6. Testing at low flows were conducted during Explosion proof verification of PureBallast 3 by DNV
PUREBALLAST 3.1 All about performance & compliance
PUREBALLAST APPROACH Design choices to meet with the needs of the Ship owner Compliance In US, California seeks approval for BW fines, USD 27,000 / day, per violation Performance Least limitations, most opportunities for worry free operations Soils, fresh water, low temperatures Opex/LCC Smart choices upfront, keeps the costs down long term Ease of use Intuitive use, and safety measures, assure that the human factor do not cause non-compliance, nor severe situations like breakdowns/explosions
