For a refinery/chemical complex project, located nearby Nanhai in the Huizhou Municipality, Svašek Hydraulics has determined the environmental impact of a waste water effluent.

The outlet of the proposed effluent discharge line is situated at a distance of 9 km from the coast line.

Water Quality standards require that pollutant concentration occurring as a result of the disposal does not exceed certain critical values.

Therefore the dilution parameters in relation to the distance from the outlet have been determined for several tidal currents.
