Ballast and Wastewater Treatments
The treatment of ballast water before discharge prevents the transport and introduction of potentially invasive species in local ecosystems through ships' ballast water. Treatment of ballast water ensures compliance with mandatory discharge standards set by the International Maritime Organization (IMO) and the U.S. Coast Guard (USCG).

Drew Marine’s 12-month reagent kit is stocked in major ports for OEM- specific Online Residual Chlorine Monitors used in Ballast Water Treatment Systems.
Wastewater Treatment
Drew Marine supplies water treatments to treat operational wastewater, including bilge water flocculants and sewage plant foam control agents. We also supply MUD CONDITIONER for removal and dispersing of mud and silt in ballast water tanks.
