Based on the regulatory and technical documentation, there has been identified a need to find ways of reducing the pollution impact zone formed as a result of treated wastewater discharge. Reducing the influence degree will allow creating a more favorable environmental condition. To intensify the mixing process, it is proposed to use the jet flow collision with the dictating flow by placing the discharging outlet head perpendicular to the river flow direction. In this study, the effectiveness of this method was confirmed using simulation and making a comparison with dispersion discharge operating co-directionally with the river flow. The simulation results have verified a significant increase in the dilution multiplicity.
