NK BWTS have been being developed under Korean R&D Program with versatile types of systems to optimize the Systems for the most effective, reliable and economic solutions to meet IMO Guidance and legislative Requirements.
The NK BWTS consist of three types of system, i.e. Ozone Disinfection Systems, Electrolysis with filter, Ultra Violet with filter. Offers the effective and Reliable solution to the problem with invasive marine species.

Key Specifications/Special Features:

– The conversion of oxygen into ozone occurs with the use of ambient air and energy.
– This process is carried out by an electric discharge field as in the corona discharge type ozone generators.
– Ozone is characterized by the following properties.
– Ozone is a powerful oxidation agent – Easily soluble in water- Colorless gas, with distinctive odor
– Short half-life; after which O3 reverts to O2
– The ozone molecule decomposes to form free radicals (OR) which react quickly to oxidize organic and inorganic compounds.
– The reaction creates HOBr and OBr-. These oxidants are the killing mechanism.
– Ozone is not sensitive to solids content in the water; therefore, no “pretreatment” required and prevents re-growth.
– Ozone system is composed of two integrated module, which consist of ozone producing part and injection part. So utility installation space in the vessel is very flexible. NK is ready to provide the global shipping industry with a fully approved, highly effective and extremely practical ballast water treatment system; supported by NK’s extensive maritime experience and global sales and service network.

Features & Applications of NK BWTS

– Flexible construction through modular system
– Integrated into existing ballast systems.
– Easy maintenance and low operating cost.
– Compact design and minimum space
– None or low-pressure losses.
– No use of chemicals.
– Effective control and monitoring system

Status of Approval

1. IMO Final approval
The NK-O3 system received final approval from the international maritime Organization (IMO) according to the IMO G9 Procedure in July 2009, at the 59th meeting of the IMO marine environment Protection committee (MEPC). 2. Type approval
The NK-O3 system received type approval from the Korean maritime administration (Ministry of land, transport and maritime affairs), according to the IMO G8 guidelines, in November 2009.
