Wastewater treatment

Wastewater, treated before it returns to the environment

Design, construction, rental and maintenance of treatment plants for sewage, grey water and industrial water, in compliance with environmental regulations.

How a treatment plant cleans the water

Inflow Sewage, grey water and industrial water

Outflow Treated water, ready for discharge

Clarification

Suspended solids settle and oils and greases float, so that they can be removed from the water.

RemovesSolidsOils and greases

Biological treatment

Microorganisms consume the dissolved organic matter. It is the core of most sewage treatment plants.

RemovesOrganic matter

Filtration

Retains the finer particles that remain in the water after clarification.

RemovesFine solids

Disinfection

Eliminates pathogens before discharge, typically with chlorine, ultraviolet light or ozone.

RemovesBacteria

Ion exchange

Resins capture dissolved ions, such as hardness or metals, and release others in their place.

RemovesDissolved chemicals

Reverse osmosis

Pressure forces the water through a semi-permeable membrane that retains dissolved salts and contaminants.

RemovesDissolved chemicals

Dewatering

Reduces the water content of the sludge that the treatment produces, so that it takes up less volume and is easier to handle.

  • Oils and greases
  • Organic matter
  • Bacteria
