The biological treatment units were operated for 37 days without water circulation and aeration supply. Six circular concret tanks of 350 liters were used. The prior period of the experiment was designed without water exchange to study the difference in water quality between two treatments. The one was control, designed without Artemia, and the other one was stocked at a density of 100 ind/l (pre-adult stage). Three replications were conducted for each treatment. The results showed the significant (p<0.05) difference in pH, nitrite-nitrogen, nitrate-nitrogen, ammonia-nitrogen, orthophosphate, total phosphate, dissolved oxygen, BOD, chlorophyll a, chlorophyll b and chlorophyll c content. Artemia were able to grow from the initial length of 2.36 mm to the maximum length of 6.06 mm on the-6th day. The brood eggs appeared on the 7th day and maximum biomass was on the 5th day. BOD was decreased from the initial level of 8.34 mg 1 to 3.4 mg/l within the detention time of 6 days. Waste water exchange was designed in the experiment to study pollutant removal rate and Artemia production. Artemia was cultured for 23 days and were able to grow from 1.88 mm to 5.34 mm in length. Brood eggs appeared on the 20th day and maximum biomass was also occurred at the same day. The filamentous bacterium infested Artemia on the 23th day. Average production of Artemia on the 23th day was 19.72 g/tank. The pollutant removal rates were the highest during the 15th day to 23th day of 0.11 mg /ind/day, 4.83 ug/ind/day, 0.53 ug/ind/day and 1.55 ug/ind/day for the removal rate of BOD, chlorophyll a, chlorophyll b and chlorophyll c, respectively.
