The Modular Biological Tanks, manufactured in High Density Polyethylene (HDPE), consist of equipment made up of several modules with decantation and an incorporated Biological Filter, for anaerobic degradation. The purified waters from the biological tank are subsequently drained and absorbed in the land itself through infiltration trenches. Given the specifications and constraints of the site, this modular biological tank can be complemented with tertiary treatment in the form of an evapotranspiration platform, where appropriate plants will affect the reduction, principally, of Macronutrients.
