Abstract: This study was conducted in two lab-scaled high rate algae cultivation ponds operating at hydraulic retention time (HRT) of 1.5 days and 1.8 days to cultivate Chlorella sp. in combination with continuous ponds raising Moina sp. to evaluate the effectiveness of biomass production. The study result showed that the flow rate of the algae pond having HRT 1.5 days is 133 mL/mins, while that of 1.8 days HRT is 111 mL/mins. The result indicated that the Chlorophyll content in the effluent of the 1.5 day HRT algae pond was 1.92 times higher than that of the 1.8 day HRT algae pond and significant difference (5%). The quality of treated waste-water was improved when the effluent of algae ponds (without algal biomass removal) went through the Moina sp. raising ponds. Therefore, we can take advantage of domestic wastewater to feed Chlorella sp. in the high rate cultivation pond and to minimize pollution matter containing in the wastewater, and at the same time Chlorella sp. could be used as feeding to Moina sp. and then Moina sp. applicable for fish cultivation.
