Zero Discharge Wastewater Evaporation
Bilge water – Gray Water – Treated Black Water Evaporator
NO DISCHARGE IS A GOOD DISCHARGE
SkimOIL ® ’s MarineVAP (MV) system is an electric powered evaporator system that safely and automatically turns waste water to vapor and evaporates it away to atmosphere.
The MarineVAP can be the final chapter for your on-board waste water management. W ith only one moving part, this simple MarineVAP system can evaporate many on-board waste water streams without operator intervention or maintenance requirements, other than to drain some concentrate after several tanks full have already been evaporated away.
With simple controls and full monitoring capabilities the MarineVAP can turn your boat or vessel into it’s own “NO DISCHARGE ZONE”
It doesn’t get any easier or safer than ZERO LIQUID DISCHARGE (ZLD)

Operation & Safety Features
Available in 7 sizes the WasteWaterVAP can evaporate up to 25 gallons per hour.
