The Hamworthy Super Trident sewage treatment plant is
the cost-effective and safe answer to disposing of waste at
sea, maintaining the quality of the world’s oceans. Fully
compatible with gravity and vacuum collection systems, it
operates on the activated sludge/suspended aeration
system, accelerating natural biological processes to produce
a clean and safe effluent suitable for discharging at sea.
The Super Trident is manufactured, installed and
commissioned working in close co-operation with the
world’s leading marine waste collection companies and was
the first non-American discharge type marine sanitation
device to meet stringent US Coast Guard testing standards.
Hamworthy Super Tridents are certified to IMO Marpol
73/78 Annex 4 Res. MEPC.2(VI). As such they produce an
effluent of sufficiently high quality to be discharged in the
majority of the world‘s seas.
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.
