The report describes experiments with an algatron system i.e., one that involves the use of a mechanically rotated culture and presents a design of a system to support two men. An average algae yield of 1500 mg1day was obtained at inner and outer light intensities of 225 and 270 ft-c, respectively, the maximum light intensities obtainable with the available light source. From 87 to 91 of incoming volatile solids were stabilized at detention periods from 0.25 to 1 day. No relation was noted between detention period and removal of P, Mg, Ca, and N. Low temperature distilled water yield was 1.83 m1sq m minambient relative humidity, 80. Water losses from an algal culture and from a carbon black suspension were closely similar and that from both, about 5 greater than from water alone. Design estimates based on the experimental conditions indicate that a maximum of 11 algatrons, each 18 in. in diameter and 4 ft long would be required per man for gas exchange, waste treatment, and water recovery about 200 litersday.
