Specific recommendations for selecting wastewater evaporators

According to the water quality selection of wastewater: The water quality of wastewater in different industries varies greatly. Therefore, when choosing an evaporator, the content of various suspended solids, oils, heavy metals, etc. in the wastewater should be considered. Generally speaking, for wastewater containing a high amount of suspended solids and oils, tube or plate evaporators can be chosen; For wastewater containing heavy metals, thin film evaporators or falling film evaporators can be chosen.

Selection based on treatment capacity: The treatment capacity of different industrial wastewater varies greatly, and choosing a suitable evaporator requires consideration of the Wastewater treatment capacity. Generally speaking, large tubular or plate evaporators can be chosen for wastewater with large processing capacities; Wastewater with smaller processing capacity can be treated using small evaporators or even natural evaporation methods.

According to the requirements of treatment effect, for wastewater that requires high treatment effect, if more than 99% of salt and harmful substances need to be removed, multi-stage evaporation or combined evaporation can be selected for treatment. In addition, in order to better treat high concentration wastewater, more advanced technologies such as electrodialysis and reverse osmosis can also be chosen.

Select based on operating costs: The operating costs of the evaporator include energy consumption, maintenance costs, labor costs, etc. When choosing an evaporator, these factors should be considered, and equipment with high energy efficiency, easy maintenance, and simple manual operation should be selected as much as possible.
