Alesd WWTP, Bihor County, Romania

Project description

---

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

The plant was designed for a dry weather maximum daily flowrate of 1.987,0 m³/day serving an equivalent population of 14.500 PE.

The plant’s treatment scheme comprised:

• wastewater treatment: preliminary treatment (screening, screened wastewater pumping, grit and grease removal), advanced biological treatment with sludge stabilization (pre-denitrification for biological nitrogen removal, enhanced phosphorus biological removal), chemical phosphorous removal
• sludge treatment: excess sludge mechanical thickening, thickened sludge mechanical dewatering, and dewatered sludge storage

The following disciplines were covered within the project:

• Process
