Marina Wash Water

Ship Shape Cleaning Solutions

This application involves treating water generated from washing the hulls of pleasure craft and commercial vessels. There are three classifications: 1) Pleasure craft which travel within fresh water (i.e., lakes and rivers); 2) Pleasure craft which travel in sea water; 3) Dry dock repair of commercial vessels. Solids retention: Cleaning the hulls of boats will involve the removal of barnacles and other organic matter that becomes attached to the hulls. Therefore, a basic dry-type trench drain (to extract the solids) and sump basin, or catch basin and sump basin is recommended. Wash water contaminants (the hulls of boats): Since barnacles contain organic matter, the water can become malodourous due to anaerobic conditions. Therefore, it is important to minimize the amount of standing water in the pit system. Hulls made of ferrous metals will oxidize, and painted surfaces (including fiberglass hulls) incorporate metals (i.e., copper) that inhibits the growth of organic matter. Therefore, metals in the wash water will need to be addressed. Oils and greases are typically a minor issue. Zebra Mussels in the North America water ways is a growing concern.

Note: The above should be considered as general information for this application. It is important to remember that each application will vary in terms of waste water characteristics, flow rates, as well as water quality requirements of the treated water.
