The Neptumatic ASTS (Advanced Sewage Treatment Plant) is expertly designed and type approved in accordance with MEPC 227(64), encompassing the stringent §4.2 Phosphorous and Nitrogen special area requirements.

Our innovative Neptumatic system processes mixed black and grey water, leveraging the vessel's holding tank as a highly efficient bioreactor. This design maximizes the bioreactor's dimensions and retention time without occupying any additional onboard space. By fostering ideal conditions for bacterial growth, the treatment unit maintains a minimal footprint without sacrificing the quality of the treated effluent water. The Neptumatic ASTS system comprises aerobic and anaerobic bioreactors (integrated into the hull or standalone) for BOD (Biological Oxygen Demand) reduction and denitrification (Nitrogen removal), a flocculation stage for solid and Phosphorous extraction, and a final stage of filtration and disinfection using a cutting-edge UV-powered free radical generator.

Invest in the Neptumatic ASTS for an advanced, compact, and highly efficient sewage treatment solution that meets the most demanding environmental standards.
