A modern engine room is required to contain so much machinery that space is at a premium. With its compact size and flexible installation options, the Ecomotive™ plant offers the most space saving solution available. Much to the benefit of designers, yards, crews and owners.
Jets™ Ecomotive™ sewage treatment plants (STB) are using the Moving Bed Biofilm Reactor (MBBR) approach. Biological treatment of waste water using MBBRs is an innovative but already tried and tested method. The technology is competitive, virtually maintenance-free and gives long operational life. Chief Engineers consulted during development are confident about the Ecomotive™ plant's first class qualities.
Why choose Ecomotive™ plants?
- Ecomotive™ plants can be built significantly more compact than traditional sewage treatment plants. Its volume and footprint sizes are only 60% to 70% compared to conventional biological treatment plants.
- The continuous movement of the biofilm reactors creates a self-cleaning action inside the reactor which automatically cleans the reactor walls and outlet grids, eliminating the need for manual intervention.
- Its flexible design allows both modular or split versions to make the most of limited space.
- The sterilisation process is based solely on UV light treatment. This chemical-free and environmentally friendly process is low-maintenance, has low operating costs and offers safe handling.
1. Inlet tank
The inlet tank mixes black water (sewage) and grey water, and provides ample capacity for peak loads. The Vacuumarator™ pump used to feed the treatment plant ensures a steady and continuous flow of waste water from the inlet tank to the bio tanks. The inlet tank can be supplied for either integrated or separate installation. Alternatively a hull tank can be used in its place.
2. Bio chambers
The bio chambers feature a seamless interface which always maintains the important retention time at the correct level. Due to the steady flow created by the feeding pump, effluent moves in an optimal pattern from chamber to chamber. Aeration keeps the suspended biofilm carriers in motion while providing oxygen for the microbes.
3. Settling tank
The settling tank features a centrally installed inlet pipe which reduces the speed of the liquid flowing into the tank, thereby improving the settling process. The funnel-shaped lower section of the tank directs sludge toward the tank's discharge point, preventing deposits inside the tank.
4. Sludge removal
The sludge removal pump ensures that excessive sludge is removed from the plant. This is an automatically controlled procedure that does not require the crew's attention.
The treated water is exposed to UV light sterilisation on its way to the clean water tank. A dedicated pump is then used to discharge the water overboard, effectively eliminating the risk of cross contamination.
