For 30 years, Optimarin has led the way in eco-friendly ballast water treatment. The company’s systems use proven UV and filter technology – completely chemical-free – to protect the world’s oceans from invasive aquatic species.
CHALLENGE
About 80 per cent of world trade is transported by ship, with over 10 billion metric tons of ballast water moved each year. This spreads invasive aquatic species – one of the greatest threats to marine biodiversity and sustainable ocean use.
SOLUTION
Proven, flexible ballast water treatment – without chemicals
The Optimarin Ballast Water Treatment System uses filtration and ultraviolet (UV) light to neutralise marine organisms, viruses and bacteria – safely and effectively. The system uses no chemicals and yields no harmful by-products.
Optimarin’s modular systems are designed for easy installation on both newbuilds and retrofits. With continuous improvements such as OptiLink™ (digital monitoring and optimisation), OptiShop (spare-parts e-commerce), and new CIP and EX solutions, Optimarin continues to make compliance simple and sustainable.
