NK Co., Ltd.

Since established back in 1980, We, at NK, started out by manufacturing parts for a ship and cladding materials but today, we have grown enough to design high-pressure gas container products. Such dramatic growth also contributed to creating shipbuilding materials with Korea's own technical knowhow. Afterwards, we relentlessly blazed new trails in the developments of fire extinguishing equipment as we developed a ballast water-treatment and offshore plant system.

Product

NK's ballast water treatment system is to introduce 2.5PPM ozone into the incoming ballast water.

By this ozone, harmful plankton, bacteria, living thing and etc are removed, and marine ecosystems are protected.

Ozone type, electrolysis type, UV type, filter type and etc are used for Ballast Water Treatment System mainly.

In particular, ozone is the most powerful type of filtration compound.

NK's ballast water treatment system got USCG AMS Acceptance, DNV, RINA, LR, NK, JG, BV Type Approval. 

Features

Ballast system a ship-board Ozone generator takes ambient air and strips away the nitrogen, concentrating the oxygen content-which is then passed through a high voltage or high frequency electrical field to produce ozone. The ozone is then injected into the incoming ballast water to oxidize and neutralize any harmful aquatic species.A percentage of the aquatic species, especially any bacteria and viruses in the ballast water, are killed by direct contact with the ozone.The remainder are killed or neutralized when the ozone reacts with other chemicals that occur naturally in seawater, to form hypobromous acid, a highly effective disinfectant in its own right.
