Wastewater Treatment

Osorno can treat any type of wastewater – residential or industrial – for a range of hydraulic loads. The treatment solution depends on the application: treatment of greywater (from bath, dish and wash water) differs from the black water (from flush toilets). The treatment of residential wastewater differs significantly from the treatment of industrial wastewater.

Our company owns the intellectual property for a number of wastewater treatment processes. Brief process descriptions are provided below.


Our BioCompact® wastewater treatment packages are ideal for small and medium flows – a perfect solution for clusters of homes, small communities, First Nations, hospitals, resorts, ships, and military applications. BioCompact® technology handles wastewater generated by 4 to 5,000 people.

Wastewater Disinfection

Osorno offers the  following wastewater disinfection technologies:

  • Ultraviolet (UV) disinfection – UV disinfection  instantaneously neutralizes microorganisms as they pass by ultraviolet lamps submerged in treated effluent.
  • Chlorine Dioxide – chlorine dioxide is ideal for disinfecting treated effluent of all types. Unlike chlorine, chlorine dioxide does not react with organic compounds, thus no harmful chlorination disinfection by-products are produced.
  • KMPS – KMPS offers strong water oxidizaton and sanitation, effectively killing microorganisms without the formation of chlorination disinfection by-products.
