Drafting of the above-mentioned project which includes the following infrastructures:

  • Pulse conduction of regenerated water, with a total length of approximately five kilometres, for the transport of effluent from the new WWTP to a control tank with a capacity of approximately thirty thousand cubic metres.
  • Network of wastewater collectors, with a total length of approximately 18 km, for the transport of flows from the existing treatment plants to the planned new WWTP.
  • A new WWTP with a flow rate of 15,000 m3/day, with a BOD5 load of 350 mg/L, with a capacity of 87,500 H-E, with a biological treatment using a dual technology combining a conventional activated sludge process and a membrane process of the ANMBR type, which will eventually consist of two conventional treatment lines for 6,000 m3/day each and six ANMBR lines for 1,500 m3/day each. The main characteristics of the waterline are as follows:
  • Common pre-treatment (thinning-degreasing),
  • Extended aeration lines: biological reactor in extended aeration, secondary decantation.
  • ANMBR lines: anaerobic reactor, membrane tank and tertiary treatment.
  • Tertiary treatment of 6,000 m3/day capacity for the effluent of the ANMBR line: ultraviolet disinfection and chlorination.
  • Thickening line: gravity thickener and dehydration by centrifugal decanters.
  • Gas line: CHP system, gas meter and torch
