Envirocleanse, LLC, owned by Charter Brokerage – a BERKSHIRE HATHAWAY company – has developed its inTank Ballast Water Treatment System (BWTS), in collaboration with Glosten, Inc., to prevent the transfer of harmful aquatic species via ship’s ballast water. With patented nozzles inside the ballast tanks and a robust hypochlorite generator, the Envirocleanse inTankTM BWTS is the most advanced and sustainable system on the market.
The inTankTM BWTS process ensures disinfection of ballast water tanks and piping through the application of a targeted CT, which is the product of disinfection Concentration (in milligrams per liter, mg/L) and disinfection contact Time (in hours) measured as total residual oxidant (TRO). The system works by circulating each ballast tank, injecting disinfectant, until the target dose is reached. This is all done while the vessel is underway, thus eliminating the risk of interrupting port operations.
