industrial and municipal sector

Hydroitalia – Colsen proposes different technological solutions based on the type of industrial wastewater to treat and the final quality requirements to achieve.
Our wastewater treatment technology solutions can be successfully applied to treat process wastewater from different industrial sectors:

  • Food and beverage industry;
  • Paper industry;
  • Chemical and pharmaceutical industry;
  • Tannery industry;
  • Textile industry;
  • Agricultural sector.

Hydroitalia – Colsen is also active in the design and construction of municipal wastewater treatment plants and/or the upgrade of the existing plants with the application of new technologies.

The principal techniques we apply for the treatment of wastewater and sludge in the these sectors are:

Primary treatment:

  • DAF unit
  • Coagulation
  • Neutralization
  • Filtration
  • Primary sedimentation

Biological anaerobic treatment of wastewater:

  • Anaerobic treatment and energy production from biogas, using UASB technology

Phosphorous removal with the ANPHOS® process:

  • The Anphos® process is a sustainable technique for the removal of phosphate from anaerobic treated wastewater. Generally, this treatment uses iron or aluminum salts that bring many disadvantages such as high costs due to the dosing of these expensive chemicals and the handling of the produces sludge containing metals, as well as the related high environmental impact. The Anphos® uses magnesium to let the phosphate precipitate into a usable fertilizer (struvite).

Biological aerobic treatment of wastewater:

  • Biological removal of nitrogen using the NAS® system (New Activated Sludge)
  • Membrane systems (MBR): micro-ultra-nano filtration and reverse osmosis

Sludge treatment:

  • Anaerobic digestion of sludge
  • Drying facility for sludge treatment
