Biological sewage treatment

 
Biological Sewage Treatment Plant series WWT-LC

With the new IMO Resolution MEPC.159(55) applicable for installations starting from January 1st 2010, new and more stringent limit values will come into force for effluent water from marine sewage treatment plants.

RWO's family of wastewater treatment systems has therefore been complemented by the biological wastewater treatment series WWT-LC fulfillingthe new MEPC.159(55)

The WWT-LC is generally based on RWO's proven Biopur WWT technology together with an additional treatment step.
