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:
