Evaporation is a technological process that allows to treat wastewater obtaining the condensed solvent (water) at a low conductivity and a concentrate, enriched in solute, whose volume is a fraction of the wastewater input.
Evaporation is widely used in the treatment of difficult industrial wastewater as:
High salinity
High concentration of organic substances
Plating
Industrial painting
Vibrofinishing
Mechanic industry
Oily emulsions
Die casting
Landfill leachate
The noblest application of the evaporation process, regarding diluted waste water, is obtained when the recovery of the concentrate and the reuse of the condensate take place.
An example of "ennoblement", concerning evaporation, is the treatment of washings after galvanic processes (Chrome plating, Nickel plating), in which the condensate at low conductivity is used as washing system and the concentrate is used as a raw material of the process.
Evaporation is also applied as a reduction system of management costs in "difficult" wastewater treatment, thanks to the reduction in volume through water recovery and eventual transfer of the concentrate to authorized third parties.
An example is the treatment of oily emulsions that, if properly treated by evaporation, allows to obtain a reusable condensate in the production process and a concentrate which may also be conferred free.
Evaporation is a process that requires energy that can be "recovered" by waste energy or directly supplied;Ecoteam studies every application optimizing both the production processes and the energy consumption.
Ecoteam has developed its own range of evaporators unit using the best technologies such as Mechanical Vapour Recompression (MVR), Heat Pump (HP) or energy flows' recovery (HW), which, whethere correctly applied, may solve many problems of industrial wastewater treatment, with management costs either acceptable or, in many cases, advantageous compared to other technical solutions.
Mechanical Vapour Recompression (MVR) technology is very interesting in terms of management low costs: if included within complex projects, by technical experts, it can lead to a lower cost of ownership compared to standart wastewater treatment discharging in a sewer.
