Sažetak
Sea water pollution is one of the serious problems of these days. Sewage treatment system on ships are designed to purify sewage water before dumping it from the ship to the surounding water. To save environment, shipping companies are testing and installing sewage water purification systems that is the higest technology standards of today. These marine wastewater treatment systems are designed to gain eff luent discharges that are of a higher purity. Advanced treatment systems (AWT) systems are still at the development stage. Comparing different manufacturers products and different working principles of this devices we got different results and diffferent d rawings of working principles. Generally speaking AWT utilize enhanced aerobic digestion with physical filtration to clean and process sewage water on ships. AWTs generally provide improved screening, biological treatment, solids separation (using filtrati on or flotation), and disinfection (using ultraviolet light) as compared to traditional Type II MSDs. Advanced treatment systems (AWT) systems is in developing process and each new models gives better results of effluent purity. Therfore thosy systems are widely used on cruise vessels than on cargo vessels with less people onboard.
