Condensers are the components which peels mud into the tank center and ensure that the mud is provided with a fluent and pumpable thickness. As solid substance contents of the muds settled in the settlement pools of treatment plants is very low (0.6-2% solid substance), condensing process is employed to increase this ratio and decrease the mud volume. In this process, solid substance contents of muds is raised to 6.5-12% solid substance. Condensers are generally designed as centrally driven and mounted on concrete or steel bridge.
