Ballast water treatment systems are needed to be approved at here and certified by an IMO member state as outlined by IMO BWMC Guidelines (G8) for approval of ballast water management systems and, if your treatment system uses an 'active substance' i.e. a chemical or chemical process, caffeine or chemical process must be accepted by the IMO according to IMO BWMC Guidelines (G9). As of October 1 2010, ten BWT systems have been type approved by member states underneath the IMO G8 guidelines with several others expected to be authorized during the next several years.

More over a decade ago, Hyde Marine, now a Calgon Carbon Corporation company, began having a solution to combat the spread of aquatic invasive species, initially within the Great Lakes, and ultimately worldwide.

Teaming program stakeholders including customers, regulators, scientists and government departments, Hyde pioneered using mechanical separation and UV disinfection to be a ballast water management solution. The USCG based its type approval of PureBallast on testing conducted from the US Food and Drug Administration at engineering consultancy DHI in Denmark. This testing was performed with similar hardware, power consumption and flow because IMO-certified version with the PureBallast 3 family. Outside the United States, where PureBallast continues to be type approved utilizing the MPN (most probable number) method, the USCG-certified system will are employed in IMO mode and then treat water with UV transmittance as little as 42%.

PureBallast features a flexible construction depending on four different UV reactor sizes. This allows for optimised sizing and competitive solutions on the wide flow range. The current type approval covers flows of 150-3,000 m³/h based around the 300 and 1,000 m³/h reactor sizes, while type approval for systems dependant on 170 and 600 m³/h reactors is predicted soon.

A benefit would be that the full spectrum of their time produced because of the LED is incorporated in the effective curing range in the fiber coatings. However, the narrow spectrum from the LED system also can create some challenges when curing fiber optic coatings which are optimized for your broad spectrum of Hg lamps. It is therefore important to complete specific material testing using the LED systems and work closely together with the fiber coating supplier to be sure the required physical properties with the coating are achieved.The UV arc lamps require replacement every 1,000 to 4,000 operating hours, while UV microwave excited lamps require replacement every 6,000 to 8,000 operating hours, preparing costs and process downtime. Other consumable items range from the magnetron of UV microwave systems and reflectors which have to be regularly cleaned and replaced. This again ends in manufacturing downtime and further cost with regard to parts and tech support.
