Designing and Development of Automated Marine Sewage Treatment Plant(m stp) using Ultraviolet Lights with Holding Tank and Shore Connection to Dis charge Pipe for Domestic Vessels
Abstract:
Some domestic ships do not have a sewage treatment plant (STP). Domestic ships with STPs cannot contin uously monitor the acceptable value or standards of predetermined treated waste liquid quality as set spe cifically in MARPOL (Marine Pollution) 73/78 Annex IV guidelines. In effect, domestic ships are susceptible to committing the maritime violation. Therefore, this study was conducted to determine the application of a Marine Sewage Treatment Plant (MSTP) among domestic ships. This MSTP used ultraviolet (UV) lights and a coliform sensor to monitor the waste liquid quality. The study was anchored in the theoretical frame works of MARPOL (Marine Pollution) 73/78 Annex IV Regulation (Pollution Regulation for Sewage) and RA (Republic Act) 9275 (Clean Water Act). The study site was John B. Lacson Foundation Maritime University (JBLFMU)-Molo, Iloilo City, Philippines. The method of this study was a laboratory experiment using several samples from the AMSTP that will be submitted for laboratory testing. This study was initially funded by the Department of Science and Technology (DOST) in the Philippines for one year (2023-2024). The invention will be submitted for commercialization after testing the application. This study will be subjected to partnerships with international shipping companies and corporations. Maritime and ship applications of this study will be used by domestic ships and sea-crafts in treating their disposal wastes plying Iloilo-Guimaras Strait. MARINA (Maritime Administration) will use this study to make decisions about maritime policies and regulations.
