In The Round

The horizontal sludge-dewatering system from In The Round Dewatering has a stainless steel drum with perforated tile lining. The drum is mounted on a roll-off frame for easy transportation and unloading.

Water trays allow for containment of discharge water. An 18,000- to 25,000-gallon batch is mixed with polymer before being filtered in the rotating drum, driven by a 1/2 hp variable-speed electric motor with a heavy-duty chain and sprocket.

The turning eliminates crusting and wet pockets, producing uniform, consistent results. The dewatered material dumps easily, and the drum is self-cleaning. Dewatering is complete after one night.
