Tank Separator

Midwestern Industries manufactures stainless steel tanks and separators (shaker screens) that help commercial and industrial laundries reclaim valuable heat energy from waste water.

Laundries transfer heat from hot waste water (approximately 130 degrees F) through a heat exchanger. The cold-water temperature is raised to within about 5 degrees of the waste water. When pit waste water with suspended solids is sent through a heat exchanger, the solids gradually reduce the heat exchanger’s efficiency and eventually plugs its tubes. A Midwestern Gyra-Vib separator can reduce solids to an acceptable level before the waste water goes through the heat exchanger. Plugging is eliminated.

To save valuable floor space, the Gyra-Vib separator can be mounted directly above the stainless steel tank. The screened, hot, waste water is stored in the tank until it is pumped to the heat exchanger.

The pit’s sloping bottom directs fiber and solids to the low corner. Water that goes to the screen passes through a separator feeder, reducing splashing and aeration. Screened wastewater is discharged into the stainless steel tank, then pumped to a heat exchanger, where incoming cold water is heated.
