Living Technologies ~ How It Works <br />000000 <br />HOW IT WORKS <br /> <br />In the claritier, the microbial communities, and any remaining <br />solids, are separated from the treated water. <br />Calm, non-aerated, water allows the remaining biological <br />solids to settle, then those solids are pumped back to the <br />closed aerobic reactor (step 3) where they are broken down <br />and metabolized further or are wasted to a holding vessel and <br />removed for disposal. <br />To achieve zero discharge, a reed bed is added to compost <br />the solids settled out of the wastewater in the clarifier. The <br />solids composted in a reed bed are removed every five to ten <br />years (depending on the size of the bed and the amount of <br />solids being treated) and often are used as a beneficial soil <br />amendment for gardeners. <br />The green surface you see in the clarifier is duck weed and/or <br />frog bit. This vegetation shades out the sun and keeps algae <br />from growing in the reactor. <br />Home I Living Machines _InC..
