Wärtsilä Hamworthy MBR technology for naval application

MEMBRANE BIOREACTORS (MBR)

Wärtsilä Hamworthy’s innovative The technology also achieved MBR PRINCIPLES OF OPERATION MBR technology is based on outstanding performance in Alaska Black and grey water pass through biological degradation and under the scrutiny of the local the automatic screen press into the membrane separation and allows authority, USCG and USEPA studies first stage bioreactor where the active for the treatment of grey and black over the past seasons. The membrane biomass degrades organic material. water to satisfy the most stringent permeate quality exceeds the most The active biomass is pumped through standards. The process produces the stringent coliform standards even an interstage filter fitted with fine highest quality discharge without without additional UV or chemical mesh. The filtered biomass, free of any requiring any addition or generation disinfection. The latest system fibrous materials, is returned into the of chemicals that are hazardous to optimisation has achieved over 25% second stage bioreactor.

The system is automated.

2 OILY WATER SEPARATORS

With the aid of Wärtsilä Oily Water THERMAL DESALINATION PLANTS Separator (OWS), the environmental aspects regarding bilge water issues are Wärtsilä Serck Como’s well-proven, to the individual requirements of easily handled with minimum impact for multi-stage flash (MSF) principle is each cruise vessel. the operation staff and with results that the most reliable thermal seawater We also offer multiple effect easily surpass legislative requirements. desalination process in the world and evaporators which are individually The Wärtsilä OWS units are IMO and is the only evaporation principle where designed to the customer’s specific US Coast Guard approved and give the heat transfer and evaporation are requirements, plate type evaporators operator effective control over all bilge strictly separated. which utilise the waste heat from media as well as over any discharges Wärtsilä Serck Como designs the main diesel engine jacket water, made into the sea. The system and manufactures multi-stage flash and rising film evaporators which guarantees a maximum oil content in desalination plants which are employed are shell and tube type, single-stage the effluent of 5 ppm (parts per million) for producing fresh water from sea units. during continuous operation. The units water, well water or industrial water. are designed to conform to the highest A special advantage of the multi- safety standards, an essential factor stage flash technology is that the for their competitiveness but also a specific heat consumption (or thermal substantial value in itself. efficiency) can be continuously adapted A complete Wärtsilä OWS consists of: • Wärtsilä Oily Water Separator • Solidpac solids dewatering unit (optional) • Onsys feed pump system (standard on OWS 500 and OWS 2500) • Bilge discharge monitoring system (optional)

VACUUM TOILET SYSTEMS

The Wärtsilä vacuum flush toilet has to install, and is supplied ready to been designed to be mechanically connect. The control mechanism can be simple, operationally reliable, and accessed without removing the bowl. stylish in appearance. By using only approximately 1 litre of Wärtsilä vacuum toilets use air water, the amount of wastewater is to drive waste from the toilet to dramatically reduced. the treatment tank or intermediate We offer the following designs for collection tank.
