Thermal Vacuum Evaporator-Crystallizer with Forced Circulation
The DESALT MFE-1 series thermal vacuum evaporator-crystallizer is designed to treat large volumes of aqueous-based streams. The equipment can be manufactured to operate using saturated steam or hot water to heat the product to be concentrated. The condensation of the generated vapour is carried out by supplying cooling water.
It is an ideal system to manage effluents with a high contaminant load and it allows the precipitation of salts from dissolved solids. The high-speed recirculation pump plays a crucial role in preventing scale formation in the main heat exchanger. Additionally, this heat exchanger is sufficiently inclined to facilitate its draining to the vessel in case of shutdown.
The operation of the equipment is fully automatic — 24 hours a day.
