Sewage Treatment Plants

Sewage treatment plants (STPs) from Wärtsilä are the most cost-effective and safe answer for every ship or offshore platform to dispose of wastewater at sea.

Vacuum Collection System

The vacuum collection systems from Wärtsilä Water & Waste use differential air pressure to transport sewage from the toilet bowls, and other sanitary fittings, to the Sewage Treatment Plant (STP) or independent collection tank.

Vacuum Toilet System

Wärtsilä vacuum toilets have been designed to be mechanically simple, operationally reliable, and stylish in appearance. By using only approximately 1 liter of water per flush, the amount of wastewater is dramatically reduced.

Single Stage Desalination Plants

Wärtsilä’s Single Stage Desalination (SSD) plant generates high quality freshwater in an energy efficient way. With a capacity from 8 to 35 tons/day, it is ideal for converting seawater for use as drinking or technical water onboard ships or offshore installations.

Horizontal inner Tube Evaporator (HiTE)

The Wärtsilä Horizontal inner Tube Evaporator (HiTE) is a multi-effect evaporator specifically designed for producing small to medium capacities of 30 to 175 tons of distillate per day. The HiTE operates smoothly even at partial load.

Multi-Stage Flash (MSF) Evaporator

Wärtsilä's Multi-Stage Flash (MSF) evaporator is used for producing distillate (fresh water) from sea, well or industrial water. The MSF is able to produce up to 1500 tons of distillate per day.

Oily Water Separators

With the aid of Wärtsilä's Advanced Oily Water Separators all environmental aspects regarding bilge water issues are easily handled. They give the operator effective control over all bilge media as well as over any discharges made into the sea.

Ballast Water Management Systems

Wärtsilä Water & Waste takes pride in developing two advanced lines of Aquarius Ballast Water Management Systems (BWMS) that enable vessels of all types to meet the performance discharge obligations. BWMS offerings, one based on filtration & UV and the other on filter & side stream electro-chlorination (EC).
