Wastewater Treatment in Shipbuilding & Marine Recycling Needs a Rethink

shipyards and marine terminals

From hull washing to ship scrapping, shipyards and marine terminals generate some of the most complex and heavily contaminated wastewater in industry.


This isn’t just oily water — it’s a mix of:

·        Emulsified fuels & lubricants

·        Heavy metals

·        Paints, degreasers, and cleaning agents

·        Suspended solids and biological load


⚠️ Traditional treatment systems—DAFs, chemical coagulation, and biological processes—struggle under these conditions. Long retention times, hazardous chemical handling, huge footprint requirements, and rising disposal fees are just a few of the challenges.


🌊 At Valence Water, we believe shipyards deserve better.

Our patented WaterMiner® and OxiMiner™ systems are engineered specifically for high-strength industrial wastewater. Designed to handle the complexity of marine waste streams, our electrochemical platform provides:


 <10-minute treatment time (versus hours or days for biological systems)

 No chemical coagulants or pH adjusters 

 80%+ reduction in consumables cost 

 30–40% less sludge, and it’s 50% drier—meaning lower disposal costs

 Odor-free, sealed system perfect for congested docks and coastal cities

 Modular & containerized, making implementation fast and scalable


💡 One major marine terminal recently piloted our system and is now replacing their chemical plant. Their projected annual cost savings exceed $2.4M, with a full ROI in under 1.5 years.


🌱 In a sector under pressure from tightening regulations, rising costs, and community scrutiny, Valence Water is helping shipyards stay compliant, reduce environmental impact, and cut operational costs—without chemicals.


Whether you're managing a dry dock, terminal, or full-scale ship recycling yard, there's a better way to treat your water.
