Importance of the new system

The inTank BWTS uses a unique dispersion system patented by the US Geological Survey for mixing the active substance in the ballast tanks. Treatment of the tanks is performed in transit, which doesn’t allow any disruption to in-port cargo operations. The Envirocleanse inTank™ BWTS can use either electrically generated hypochlorite or bulk chemical as the means to provide disinfectant. Having these options allows the user flexibility to choose the system which best fits their vessel profile. 

“There is no filter utilized; there are no repower requirements for the vessel; there is no crew interaction required in port. inTank has a compact and flexible profile that never impacts or slows down cargo operations, ballast loading or discharge operations. In short, one of the primary concerns of today’s ship operators – BWTS operational delays and related demurrage – has effectively been eliminated. Add all of these advantages to the fact that we will likely be the most cost competitive system on the market”, states Matt Hughes, EVP of Sales and Marketing, Envirocleanse.

Thus, “the inTank BWTS is an important and unique addition to the current offerings in the marketplace.”
