EBP was hired to develop a treatability study of industrial effluents generated by rainwater runoff in an industrial area. The main challenge The variability of concentrations of interest due to generation dynamics is one of the main challenges of this work.

The objective of the study was to collect and characterize the effluents generated in the areas and then test applicable treatment processes to meet legal disposal standards.
 

Sample collection planned according to representativeness was carried out in a sequence of rainfall occurrences and combined with in situ analysis techniques of the parameters of interest. The samples sent to the laboratory were characterized through physical-chemical analyses.

In parallel, aliquots of the effluent were combined to apply pre-defined treatment techniques on a laboratory scale (bench test).

Treatment techniques were defined and organized into 5 specific routes for the conditions observed in the effluents during characterization.  Each defined route resulted in lower concentrations, whose values ​​were evaluated and compared with the control sample.

Among the routes evaluated, it was possible to consider the processes that proved to be more or less efficient in meeting the objective.

The result made it possible to establish the best treatment route for the chemical substances of interest on a laboratory scale, bringing gains in defining an engineering concept that adheres to the customer's needs.
