Project description

Within this contract, our team elaborated process design of the technical proposal for Ploiesti (Prahova county, Romania) wastewater treatment plant covering preliminary treatment, primary treatment, advanced biological treatment and sludge treatment up to 25% solids content.

The plant was designed for a dry weather maximum daily flowrate of 36.000 m3/day serving an equivalent population of 200.000 PE.

The plant’s treatment scheme comprised:

  • wastewater treatment: preliminary treatment (wet weather wastewater overflow, screening, grit and grease removal, septic sludge acceptance station), primary treatment (primary clarification), advanced biological treatment (pre-denitrification for biological nitrogen removal, enhanced phosphorus biological removal), chemical phosphorous removal
  • sludge treatment: primary sludge gravity thickening, excess sludge mechanical thickening, thickened sludge screening, thickened sludge anaerobic digestion, biogas cogeneration, digested sludge mechanical dewatering, and dewatered sludge storage

The following disciplines were covered within the proposal:

  • Process
  • Hydraulics
  • Mechanical
  • Operational expenditure
