Project description

---

Within this contract, our team provided technical assistance for process design for Oradea municipality (Bihor county, Romania) wastewater treatment plant covering preliminary treatment, primary treatment, advanced biological treatment and sludge treatment up to 20% solids content.

The plant was designed for a dry weather maximum daily flowrate of 165.287,0 m³/day serving an equivalent population of 251.333 PE.

The plant’s treatment scheme comprised:

• wastewater treatment: preliminary treatment (screening, screened wastewater pumping, grit and grease removal), primary treatment (primary clarification), advanced biological treatment (pre-denitrification for biological nitrogen removal, enhanced phosphorus biological removal), chemical phosphorous removal, polishing reefs lagoon
• 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 project:

• Process
