BIOLAC System Information

There are over 250 installations in the United Stated and another 350 international installations covering the full spectrum of wastewater treatment applications. Control for air distribution to the aeration chains and the basin’s dissolved oxygen content provide moving waves of multiple oxic/anoxic environment. These “zones” provide for nitrification, denitrification, and biological phosphorous removal in the patented Wave Oxidation process. Rising air from fine bubble diffusers, suspended near the bottom of the basin, create lateral displacement of the floating aeration chains. Their slow, continuous oscillation creates unique high-efficiency mixing using one third to one quarter the energy of fixed systems.
