Sludge Management System

Posted by Irina Tabakina

Scienco/FAST has introduced a new way to deal with sludge with its standard MarineFAST Marine Sanitation Device, which meets MEPC.159(55) or providing secondary treatment, incorporating about one month of internal sludge storage or three months with larger systems. For vessels requiring a longer period, the MarineFAST BMS provides an aerobic sludge digester with long term internal storage to extend the sludge storage.
Operation is completely automatic and hands-free, and the sludge is enclosed in tanks and piping – no need for personnel to come into contact with sewage or sewage sludge. According to the manufacturer, MarineFAST BMS reduces sludge volume by 65% compared with other systems. No strainers, filters, membranes or centrifuges are required. Vents are used to weather through the FAST unit; no separate vent piping required. The system does not affect the dimensions, weights or operation of the FAST unit.
The MarineFAST BMS system uses an aerobic process with no corrosion or odor from septic sewage or sewage sludge. Tanks are designed to ABS deep tank standards, protection against corrosion is exceptional and all machinery, piping and controls meet USCG requirements for inspected vessels. When settled, the activated sludge exhibits about 4% concentration in water.
