The roots of the vegetation provide <br />surfaces for the growth of attached microbial populations that <br />assist in the wastewater treatment. The plants serve as habitat <br />for beneficial insects and organisms that graze on microbial <br />biomass. <br />The plants used to cover the open aerobic reactors include <br />tropical and sub-tropical species that have been tested and <br />found effective in treating wastewater as well as providing an <br />optimal habitat for the rest of the ecology. <br />These planted reactors are beautiful and make the Living <br />Machine feel like a botanic garden. Open aerobic reactors and <br />'polishing' reactors (step 6) set Living Machines® apart from all <br />other wastewater treatment systems. <br />These reactors reduce BOD to secondary levels and complete <br />the nitrification process. The size and number of these <br />reactors are determined by the required BOD reduction; and <br />design water and air temperatures. Removable fine membrane <br />air diffusers keep the contents completely mixed. <br />Home I Living Machines. Inc.
