Ballast BWMS
The N Ballast BWMS is a brand new system independently developed by our company to meet the IMO and USCG ballast water discharge standards. The system applies 50μm self-cleaning filter and micro-filtration membrane to remove solid particles, organisms and even bacteria, and inject with inert gas – nitrogen.
Ballasting: The overboard sea water is sucked through sea rough filter by ballast water pump, and then enters filter unit, membrane separator into ballast tank, while it is charged nitrogen.
De-ballasting: The ballast water in ballast tank is sucked by ballast pump to discharge overboard.
1. Safety and environmental protection – physical treatment process, no use or produce chemical substances.
-
Direct discharge during de-ballast – direct discharge during de-ballast without secondary treatment.
-
Low carbon & energy saving – low power consumption for system operation.
-
Nitrogen for anticorrosion – nitrogen for de-oxygenation, reducing corrosion.
-
Less sediments – two steps of filtration, high efficiency to remove impurities in water.
-
Wide application – no limitation for ballast water salinity, temperature, turbidity.
-
Easy operation – one key start, operate at anytime.
-
Low installation and operating costs – few pipe connections; small cable consumption, small specifications; low power consumption, less replacement of wearing parts.
