waste & fresh WATER MANAGEMENT Wärtsilä Hamworthy Membrane Bioreactor (MBR) Systems Wärtsilä Hamworthy’s innovative MBR system is an evolution of the company’s proven sewage treatment technology for handling grey and black water waste. The technology is an advanced wastewater treatment process based on biological degradation and membrane separation. It delivers the highest quality discharge without requiring the generation or addition of chemicals hazardous to the maritime or shipboard environment.
automatically. This allows unattended operation, with reduced maintenance requirements and lower long-term operating costs. The systems are compact and modular in design, suitable for between-deck installations, and are adaptable to customer new build specifications. The STA-C and ST-C series sewage treatment plants are certified to meet IMO MEPC 159(55) guidelines, and are recognised by leading shipbuilders.

Wärtsilä Hamworthy Vacuum Toilets
Wärtsilä Hamworthy miniMBR systems are smaller, more compact versions of the company’s innovative MBR technology for handling grey and black water waste. By building on our successful experiences and working closely with our customers, we have been able to optimise the miniMBR system to produce an effective compact package. It is ideal for use on smaller cruise and naval vessels, plus ferries with up to a 200 complement, as well as FPSOs and accommodation platforms.
Wärtsilä Hamworthy vacuum toilets use air to drive waste from the toilet to the treatment tank or intermediate collection tank. This contemporarily styled toilet has a built-in vacuum breaker and flush memory, is simple to install, and is supplied ready to connect. The control mechanism can be accessed without removing the bowl. By using only approximately 1 litre of water, the amount of wastewater is dramatically reduced.
Wärtsilä Hamworthy Sewage Treatment Plants Wärtsilä Hamworthy’s market-leading sewage treatment plants offer easy-to-install, trouble-free systems for some of the harshest environments on the planet. Optimised for the treatment of black and grey wastewater flows, and suitable for conventional gravity and vacuum fed collection systems, all plants in our STA-C and ST-C range are controlled
Wartsila Hamworthy Vacuum Collection System The Wärtsilä Hamworthy vacuum collection system uses differential air pressure to transport sewage from the toilet bowls, and other sanitary fittings, to the Sewage Treatment Plant (STP) or independent collection tank. Ejectors can be mounted direct to the STP for modular construction without the need for a separate collection tank, and only a small amount of flush water is needed compared to conventional gravity systems.
