The dynamic sludge mixer MBV design is simple, robust and compact. It can be easily adapted in existing or future sludge stabilization process (for odour removal and / or agricultural purposes) of any water and waste water treatment plant. The sludge mixer is fed with hydrated lime or quick lime by a mechanical discharge and metering unit.

The double counter-rotating rotors are fitted with intersecting and adjustable paddles. They optimise the quality of the mixture as the sludge progresses through the body of the mixer. The cranked shape of the paddles, specifically designed for this application, ensures that the sludge is mixed for the time necessary according to its properties.
