The vessels also will have a 23-foot- wide stern ramp with 160-ton ca- pacity, as well as one ramp and three elevators as internal equip- ment. In addition, the ships will be equipped with four twin sets of flush hatch covers that will enable the use of shore-based gantry cranes. The vessels' service speed will be 20.3 knots. The total investment in the four ships, including ancillary equipment, will exceed $100 mil- lion, according to Hellenic Lines.

Simplicity is the key to the Demco packaged sewage treatment plant. And your key to low maintenance operation that is fast, effective, reliable and economical. Simple Low Maintenance Opera- tion. Raw sewage enters the plant and passes through aeration cham- bers by gravity. What could be more simple than that? There are no pumps or intricate mechanisms to clog or break down. Wastes are reduced by aeration and consumed by an exclu- sive mixture of bacteria-enzymes. Final disinfection is by dry soluble chlorine tablets. Fast. Special bacteria-enzymes accelerate degradation and maintain a viable biology. In a day's operation, the Demco system will process as much as 25% more sewage than competitive designs. Standard Demco units process from 325 to 12,500 GPD. Larger systems are available for special applications. Effective. Demco system design treats all degradable wastes includ- ing difficult materials like paper, grease, oil, detergents and garbage processed through a disposal with impressive results. When operated using recommended procedures, Demco sewage treatment plants will remove 85-95% of BOD and sus- pended solids. The effluent contains a minimum chlorine residual of 1 mg./ liter and 1,000 or less coliform bacteria per 100 milliliters. Reliable. Demco sewage treatment plants perform. Performance that has earned National Sanitation Foundation certification (Standard 23). Demco plants are also certified by the U.S. Coast Guard, and meet or exceed U.S. Geological Survey and anticipated IMCO effluent requirements. Reduction of BOD and suspended solids below 10PPM is common with the addition of the Demco Dual Media Tertiary Filter downstream of the basic plant. This quality effluent exceeds all published EPA require- ments for land and offshore sewage discharge.
