The client wanted to improve the treatment efficiency of the existing industrial wastewater pre-treatment plant to maintain the effluent standard requirements.
Veolia Water Solutions & Technologies offered a "turnkey" design & build solution in order to improve the efficiency of the existing industrial wastewater pre-treatment plant. The plant needed to be completely refurbished.
Veolia Water Solutions & Technologies refurbished the existing industrial wastewater pre-treatment plant, to attain a treatment capacity of 750 m3/d.
The project covered both the wastewater and sludge treatment lines and consists of:
Design capacity : 750 m3/d
