This study tested pilot series small-size cyanobacteria bioreactors to treat human urine. The proposedsystem immobilized cyanobacteria on pieces of gauze mesh inserted in transparent plastic tanks filledwith water. Between each tank were two connecting plastic tubes: the first tube was used to deliver waterinto the bottom of the adjacent tank from the previous tank; the second tube was used to deliver waterfrom the adjacent tank top to the next tank. The system was placed on gently sloping land to allow gravityto facilitate water delivery. After six runs of immobilized cyanobacteria mesh bio-adsorption, the urinebecame reusable water with lower quality than drinking water. This easily operated, cost-effective urinewater recycling system may be used in underdeveloped rural areas or space crafts for long-term travel byrecycling water for biological life support systems. In addition, the produced edible cyanobacteria may beused as animal feed.
