Waste Water Treatment is a process to convert water no longer needed or suitable for its most recent use into an effluent that can be either returned to the water cycle with minimal environmental issues, or reused.

Tecniplant solutions allow the removal of contaminants from water reuse for various purposes. Disposal or reuse options are the basis for the treatment decisions. Acceptable impurity concentration may vary with the type of use or location of disposal and some method of treatment are applicable to both water and wastewater.

The processes involved in removing the contaminants include pre-treatment, primary treatment, secondary treatment, tertiary treatment, disinfection, ultimate disposal and sludge treatment.





The Pre-Treatment consists in water conditioning through physical separation with the following phases:

  • Screening
  • Equalization
  • Oil Separation

Primary Treatment

Primary Treatment is divided in chemicals for the pH adjustment, removal of nutrients and metals and physical treatments for the removal of suspended solids consisting in:


  • Neutralization
  • Coagulation and Flocculation


  • Sedimentation
  • Flotation

Secondary Treatment

Secondary Treatment for the removal of soluble biodegradable organics consisting in:

  • Activated Sludge
  • Moving Bed Biofilm Reactor (MBBR)
  • Sequencing Batch Reactor (SBR)
  • Rotating Biological Contactor
  • Trickling Filters

Tertiary Treatment

Tertiary Treatment for the remove of non biodegradable organics, ions macromolecules, nutrients and odors consisting in:

  • Membrane Biological Reactor (MBR)
  • Ultrafiltration and Reverse Osmosis (RO)
  • Carbon Adsorption
  • Ion Exchange
  • Sand Filtration


Disinfection for removal of living organism consisting in:

  • Chlorination
  • Ozonation
  • Ultra Violet Sterilizer (UV)

Sludge Treatment

The Sludge Treatment consists in:

  • Thickener
  • Vacuum Belt Filter
  • Drum Vacuum Filter
  • Pressure Filter
  • Aerobic Stabilization
  • Anaerobic Digestion
