Evac waste water systems chosen for Transpetro tankers building at EAS

João Cândido, the first in a series of ten 160, 000 dwt Suezmax tankers building at Brazil’s Atlântico Sul Shipyard (EAS) for Transpetro, is equipped with Evac’s complete wastewater system. Evac’s system has also been selected for the series of five 110,000 dwt Aframax tankers being built by Atlântico Sul.

The delivery of MT João Cândido is a historical milestone for the shipbuilding industry in Brazi and Evac says it is proud to be a supplier for this vessel. All wastewater on the new tanker is handled and cleaned by Evac’s latest water treatment technology.

Evac provides a complete wastewater management solution, capable of handling all black (sewage) and grey waters (from galleys, sinks, showers) onboard, meeting the strict environmental requirements of IMO, the International Maritime Organization. The system operates fully automatically with little need for maintenance.

Evac, with headquarters in Finland, is a company in the Zodiac Marine & Pool Group and has been in the Brazilian market for some 20 years – where other deliveries include the vacuum systems for the Administrativo do Governo de Estado de Minas Gerais – the State Administrator’s and Governor’s Palace complex, the Santos Dumont Airport and the Rodoviário Terminal in Rio de Janeiro as well as for the Recife International Airport.

On the Suezmax tankers, Evac’s wastewater system includes:

• Evac’s vacuum collection system with ejectors, including the quietest toilets on the market, of Evac 910 type. The system has a very small size and footprint onboard and it uses 80% less water than traditional toilets. The system was built by EAS and Evac in cooperation, with the yard supplying the holding tanks used by Evac’s vacuum collection units.
• Evac’s MBR 24C type advanced biological membrane-based wastewater treatment plant, based on flat sheet micro-filtration membranes, developed specifically for wastewater treatment. The Evac MBR is directly combined with the Evac vacuum system as a total wastewater management package. In 2010 IMO’s new resolution MEPC159 (55) entered into force with new and more stringent limit values for effluent water from marine sewage treatment plants. Evac’s wastewater systems meet and surpass these requirements.
