Harlau WWTP, Iasi County, Romania
Project description
Within this contract, our team elaborated full technical proposal for Harlau city (Iasi county, Romania) wastewater treatment plant covering preliminary treatment, advanced biological treatment and sludge treatment up to 25% solids content.
The plant was designed for a dry weather maximum daily flowrate of 4.682,0 m3/day serving an equivalent population of 19.009 PE.
The plant’s treatment scheme comprised:
- wastewater treatment: preliminary treatment (wet weather wastewater overflow, screening, grit and grease removal, preliminary treated wastewater overflow, septic sludge acceptance station), advanced biological treatment with sludge stabilization (simultaneous denitrification for biological nitrogen removal, enhanced phosphorus biological removal), chemical phosphorous removal
- sludge treatment: excess sludge gravity thickening, thickened 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
