Project description


Within this contract, our team elaborated full technical proposal for Iasi municipality (Iasi 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 255.120,0 m3/day serving an equivalent population of 933.333 PE.

The plant’s treatment scheme comprised:

  • wastewater treatment: preliminary treatment (wet weather wastewater overflow, overflowed wastewater pumping and receiving water discharge, screening, influent wastewater pumping, grit and grease removal), primary treatment (primary clarification, overflow), 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 anaerobic digestion, biogas cogeneration, digested sludge mechanical dewatering, and dewatered sludge storage

The following disciplines were covered within the proposal:

  • Process
  • Hydraulics
  • Mechanical
  • Structural
  • Architectural
  • Electrical
  • Instrumentation, control and automation (SCADA)
  • Roads, platforms and alleys
  • Landscaping
  • HVAC
