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.
