Most ballast water treatment systems are in-line systems, i.e. the water is brought prior to it being brought into the tank. The M H Systems “InertBallast” is an in-tank system, meaning that after the ballast water is brought into the tank, it is treated to achieve the “organism kill” conditions making the toxic to both oxygen based and non-oxygen based organisms. This is achieved by infusing/diffusing the ballast water with inert gases to drive down the percentage of dissolved oxygen in conjunction with de-oxygenation that is central to the proprietary technology by M H Systems for ballast water treatment.
In-line BWT systems, primarily the UV and Chemical systems are the prevalent BWT systems. In the context of latest US Coast Guard regulation (and direction) these inline system are required to exchange its ballast water outside 15 mile offshore. That is the ‘Belt and Suspenders’:
MHS InertBallast SYSTEM DOES NOT REQUIRE BELT & SUSPENDERS
One of the biggest differences between the in-tank system and in-line system is the lack of complexity of in-tank system. The M H Systems InertBallast in-tank system consists basically of a booster pump for boosting the pressure of gases from an inert gas generator (already exists in oil tankers), a control system for controlling the valves for directing the inert gases to specific ballast tanks, plastic piping for transporting the inert gases, and diffusers located at the ballast tanks.
Simplicity is the focus of the system design. In fact, man operation can even replace the control system for valve operation. There is little to malfunction on this system. Control is basically an on/off switch for each ballast tank. “ON” routes inert gases to a specific tanks, and “OFF” shuts of the flow of inert gases.
