Chemical-physical batch plants

SBR (Sequencing batch reactor)
biological plants

  • Exhausted concentrate treatment
  • Treatment of discontinuous effluents
  • Variable flow rate effluent treatment
  • COD reduction
  • BOD reduction
  • Nitrification
  • Denitrification
  • Phosphates removal
  • Single section treatment
Vantages of discontinuous batch plants:
  • Water monitoring before the discharge
  • Flexible treatment
  • Possibility to repeat the treatment
  • Small area for installation
  • Economic saving

Chemical-physical batch plants

Chemical-physical discontinuous plants are suggested for discontinuous and irregular effluent flow-rates.
Chemical-physical discontinuous plants have the same treatment sections of chemical-physical continuous plants (but in sequential way):
  • Acidification
  • Coagulation
  • Neutralization
  • Flocculation
  • Sedimentation / decantation

SBR (Sequencing batch reactor) biological plants

SBR biological plants are composed by systems that equalize, aerate, denitrificate and sediment the effluent in a single reactor or in more reactors with determinated operative sequenceses.
SBR plant develops a mix of bacteria cultures that are able to remove COD, BOD and Nutrients present in the treated effluents.
The main sections of SBR plants are:
  • Loading
  • Equalization
  • Aeration
  • Sedimentation
  • Discharge
