VALMET INTRODUCES SCRUBBER WATER TREATMENT SYSTEMS

Wednesday, January 20, 2021 

Exhaust gas cleaning system manufacturer Valmet is launching an enhancement to its scrubber portfolio with a patented and fully automatic water treatment solution for the marine scrubber system and exhaust gas recirculation system, in line with IMO guidelines.

Valmet was the first supplier to introduce a hybrid scrubber to the market, and the Valmet Marine Water Treatment system is a further part of Valmet’s continuous development of marine solutions towards more sustainable ship transport. The Valmet Marine Water Treatment system consists of four different modules that can be fitted in different vessel layouts. Due to the layout flexibility, the water treatment system can be installed in newbuildings as well as retrofits.

Valmet's Marine Water Treatment needs no addition of chemicals to treat the effluent. Daily cleaning is carried out with plain sea water. For weekly cleaning freshwater and a small chemical dose is needed. Low chemical consumption, little freshwater consumption, as well as minimal maintenance save both costs and the environment.

The unit has been designed to handle high total solids contents without the risk of clogging the membranes. The bleed off water from closed loop circulation is concentrated, and when about 10% to 15% total solids content is reached, the concentrated sludge is pumped into a sludge tank. High total solids content leads to low volume of sludge hence low disposal costs in port.

Lishan Wu, Valmet Product Sales Manager, Marine Emission Control, said: “With the help of Valmet DNA automation system, the water treatment solution ensures flexibility and reliability in optimising the water treatment process."

“Our expertise from other land-based industries and decades of development work have led us to this innovative solution for vessels. Our target is to support our customers in their business in a more sustainable way, as well as make it possible for them to conduct responsible business, emissions controlled. At the moment, it is extremely important to support maritime businesses towards lower emissions. This technology contributes clearly to these aims,” said Anssi Mäkelä, Valmet Senior Manager, Sales and Technology, Marine Emission Control.
