Violations of vessel sewage regulations should be reported to your local U.S. Coast Guard office or National Response Center, as well as to your local marina (if appropriate). The biological sewage treatment plant consists of four interconnected compartments, raw sewage or effluent passes through a bar screen, which breaks it up into smaller particles from where it passes into primary compartment. So the goal of sewage treatment for plants is to reduce the contaminants within it so that it meets the environmental regulations for disposal, doing so in the most energy efficient manner. Violations of vessel sewage regulations should be reported to your local U.S. Coast Guard office or National Response Center, as well as to your local marina (if appropriate). Thus, our process is more efficient than standard FBBR in the market place and also compared to the activated sludge process, it has a smaller reactor size, higher removal efficiency, reduced odour annoyance and robustness towards hydrodynamic variations and shocks in the inlet concentration.
