NEI Treatment systems is a pioneer and a market leader in provisioning large commercial ships with Ballast Water Treatment Systems. NEI's VOStm system was the first in the world to receive IMO approval (Liberia,2007). NEI enables its customers to cost-effectively comply with US discharge regulations, now becoming a law and being enforced, and the pending IMO discharge regulations that protect the world's oceans and waterways from invasive aquatic plants and animals. NEI's VOStm system induces a low oxygen environment in the ballast tanks which safely and cost-effectively eliminates harmful aquatic organisms without the use of active substances. At the same time, this low oxygen, non-toxic environment protects the ship's ballast tank coatings against degradation and the corrosion of steel plates, for the lifetime of the ships.
