Ballast water

Two Choices / One System

The primary advantage of the Envirocleanse inTankTM system is its superior method of chemical delivery. Our patented nozzle, coupled with an inTankTM distribution piping system is able to treat each ballast tank individually by distributing the active ingredient, sodium hypochlorite (NaOCl). Envirocleanse offers multiple options to produce NaOCl: bulk dosing and an onboard, electrochlorination generator. If the bulk-dosing option is selected, the user will simply maintain an adequate level of liquid NaOCl in a bulk-dosing tank. The system then distributes the chemical as needed when the ballast water treating cycle begins. In cases where the owner or operator chooses an on-site generator, seawater from the sea-chest is used to produce NaOCl that is similarly distributed to the ballast tanks. Both means provide a safe and reliable method to deliver the active substance into the ballast tank and ensure a compliant discharge.

Ballast Water Management Systems

The Envirocleanse inTankTM BWTS utilizes salt water and Electrochemical Activation (ECA) to generate Sodium Hypochlorite (NaOCl) as the active substance to achieve ballast water discharge standards. The circulation module mixes one tank at a time where ballast water quality is assessed and the generated disinfectant is applied until the target Total Residual Oxidant (TRO) level is reached. The Envirocleanse inTankTM BWTS is effective in all water types including fresh, brackish, and marine water.

The circulated ballast water is returned through the patented in-tank nozzle mixing system that ensures even chemical distribution (see figure below). After an initial hold time, the circulation module rechecks the TRO in each tank, applying more NaOCl if required. This is repeated for all ballast tanks that require treatment. Prior to discharge, the circulation module checks the remaining TRO in the ballast tanks and applies Sodium Thiosulfate to neutralize any remaining active substance.

The inTankTM BWTS does not filter the ballast water on uptake, which is different than most in-line systems. To ensure consistent and effective kill of target organisms and pathogens, the Concentration-Time (CT) treatment approach is utilized. The recirculation capacity enables monitoring and re-dosing to meet the target combination of oxidant dose and hold time. The ability to dose in-tank and re-dose ensures effective treatment regardless of organic and inorganic loads in the ballast water.
