For tertiary wastewater treatment applications, the AlgaePac system from Oldcastle Precast features patented Algaewheel technology which provides a diverse ecological environment for wastewater discharged to Surface, Subsurface, and/or Reuse situations. Using a symbiotic relationship between algae and bacteria, the AlgaePac system combines Algaewheel technology, simple clarification processes enhanced by the natural coagulating effect of algae filaments, and disinfection to provide effluent treated to tertiary standards.
