Cooling water and anode washing WWTP


For this leading aluminum manufacturer EURO MEC tailored a water treatment system which served to convert anode cooling water management from a semi-open circuit to a closed circuit system and the collection and pretreatment of wastewater discharged into the civil sewer network. The main interventions planned and executed by Euro Mec were:
  • interception of waste water from anode washing and cooling water systems which previously discharged directly into the sewer network; 
  • installation of two heat exchangers (one reserve) for cooling water and a new cooling tower located next to the molding production line, together with feed pumps and closed circuit piping serving the aforementioned exchangers;  
  • realization of a treatment plant for the waste discharged from the closed circuit system. The treatment includes stages of sedimentation and oil separation (sediflotation), followed by filtration through filter beds of silica sand / anthracite. Installation of new pressure piping for the transfer of treated wastewater to the civil sewer network.
To ensure the correct operation and maintenance Euro Mec carried out a year of plant management following the start up of the installed plant.
