As a result of vague recommendations of IMCO on the treatment of sewage and its disposal, shipowners will be forced to continue the practice of meeting differing requirements depending on which ports their vessels use. This article presents five choices of sewage treatment plants, and briefly describes the method of operation of each type of plant. The units described include: 1) systems in which biological reactions take place to reduce the B.O.D. of the effluent to a particular limit; 2) systems in which the sewage is retained in the vessel during a port stay and released at sea or at a port facility; 3) systems which reduce the B.O.D. by the addition of chemicals; 4) systems which macerate the sewage to produce a small particle size which is then subjected to disinfection by contact with a hypochlorite,; and 5) sewage incineration systems.
