Sewage Treatment PlantSuper Trident

Water Systems

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.

Please refer to your local Hamworthy representative for

details on the latest developments in wastewater

technology.
