In July of 2022 a sludge dewatering system was installed in Mont Belvieu, Texas, at the Cotton Bayou Wastewater Treatment Plant. This system is designed to operate for 16 hours a day and is equipped with remote operation features! One multi-disk screw press dehydrator MDQ-354 CL, with two shaftless screw conveyors are installed.

The dewatered sludge is discharged into a shaftless screw conveyor that transfers the cake to an additional shaftless screw conveyor on an incline ending with the dewatered sludge falling into a dewatering dumpster to be removed by the staff of the Mont Belvieu Public Works staff.
