Wetland-based blackwater systems, such as <strong>the</strong> proprietary Living<br />
Machine®, depend upon biomimicry and natural processes to filter<br />
blackwater. Typically, <strong>the</strong> system components include;<br />
• An anaerobic settling tank to initially remove large solids from<br />
<strong>the</strong> blackwater<br />
• A bi<strong>of</strong>ilter to initially filter <strong>the</strong> blackwater and reduce odors<br />
that may occur in anaerobic conditions<br />
• A series <strong>of</strong> aerobic tanks containing a variety <strong>of</strong> algae,<br />
organisms, hydroponic plants, plankton, etc. help to process<br />
<strong>the</strong> water, removing fine particles and unwanted bacteria<br />
• A purification chamber typically utilizing UV sterilization,<br />
chlorination, or ultrafiltration<br />
