VSV Sludge/Water Heat Exchanger Brochure

The VSV Sludge/Water heat exchanger is a “Tube in Shell” heat exchanger used to heat and cool biological sludge. The sludge tubes are a circular cross section surrounded by rectangular cross section water channels. The flow of the sludge and the water is cross current for highest efficiency. The VSV heat exchanger utilizes a modular construction, with each heat exchanger being designed specifically for each application. There are five diameter sludge tube sizes available. There is the flexibility of one to four sludge tubes per level and 2 to 22 levels in the heat exchanger design. The sludge tubes can measure up to 20 feet in length. This design flexibility optimizes velocity, Reynolds number, shear rate, and pressure loss in the sludge flow for efficient heat transfer. This also provides flexibility in the physical size of the heat exchanger, as the design is easily modified to fit in an existing plant.
