Sewage Treatment PlantSuper TridentSTA-C series and ST-C series

Water Systems

Hamworthy is the world´s leading manufacturer of marine

sewage treatment plant. For over three decades Super

Trident sewage treatment plant have been widely regarded

as standard specification on all vessels.

Plant installed on existing ships on or after 1 January 2010

and on new ships whose keels are laid on or after this date

must meet the new IMO MEPC 159(55) guidelines, which

are more stringent than the longstanding IMO MEPC 2(VI)

guidelines.

The STA-C and ST-C series of Hamworthy plant is certified

to meet IMO MEPC 159(55).

An STA-C or ST-C unit is fully compatible with gravity and

vacuum collection systems, and uses the activated sludge

system, which accelerates natural biological processes.

Chemical disinfection and dechlorination are employed

to produce a clean, safe, effluent suitable for discharging

at sea.

To enable ships to continue discharging black and grey

water in especially sensitive waters, where regulations

demand tighter controls, Hamworthy have developed a

range of MBR (Membrane Bioreactor) plants.

Please refer to your local Hamworthy representative for

details on the latest developments in wastewater

technology.
