Ballast water treatment with a Wärtsilä Aquarius ® EC system is achieved through a simple and efficient two stage process. Upon uptake the sea water is first passed through a back washing filter (1st Stage) and then the filtered sea water passes through a static mixer, where the disinfectant generated from the side stream electrolysis unit (2nd stage) is injected to ensure a maximum level of 10ppm in the treat

MATERIALS Supporting Framework: Static Mixer: Filter: Module Pipework: Consumables: PROVEN FILTRATION During uptake ballast water passes through a screen filter. The filter removes particulates, sediments, zooplankton and phytoplankton over 40 micron. Automatic filter cleaning ensures and maintains filtration efficiency. ELECTRO-CHLORINATION Disinfectant TRO (total residual oxidant) is produced by an EC cell module, comprising of electrolytic cells, specifically designed to generate sodium hypochlorite from sea water. The sodium hypochlorite generated is pumped into the main ballast line, where...
