RWO Marine Water Technology, part of Veolia Water Solutions and Technologies, has received an order for three of its Cleanballast water treatment systems from Japanese shipyard SHI-ME.

The Sumitomo Heavy Industries (SHI-ME) shipyard, located in Yokosuka, Japan, has built in excess of 1,300 ships.

The ballast water treatment plants of the long-established Bremen company RWO will be installed in 2012, in three Aframax tankers currently being built for a Cypriot shipowner.

The Cleanballast water treatment system, with a maximum capacity of 3,000m/h, will be equipped with several of RWO’s advanced disinfection systems operating in parallel.

This allows the system to cater for differing rates of ballasting and de-ballasting.

According to RWO, SHI-ME selected Cleanballast for its low energy consumption, vibration resistance and its option for intermittent operation.

In addtion, Cleanballast works in low conductivity water, needing no external additional chemicals for the disinfection.

The fully IMO type-approved Cleanballast technology was developed by RWO in 2003 and has been technologically refined over the years and tested in real-life conditions.

Even under extreme situations, such as high sediment concentrations, Cleanballast was reported to have exceeded the IMO test requirements.

The design and the testing of the plant under realistic environmental conditions is an essential prerequisite in order to guarantee a rapid and safe intake of ballast water and short times in port.

In addition, the efficient removal of the sediments considerably lowers tank cleaning costs and prevents the loss of valuable load capacities.

Many years of experience in the treatment of water and wastewater on board ships and offshore platforms helped the Bremen Company in the development of the modular system, which stands out for its technological reliability, sustainability and economical operating and investment costs.

The Cleanballast system, which can operate not only in sea water but also in waters with low salt content, is offered for various capacities and configurations for both new builds and retrofitting.
