ABSTRACT
The study used two types of algae to reduce contaminants in dairy wastewater, using Lyngebia and Chlorella. COD, PO4, NO3 and algal growth measured, at 22 ° C and 32 ° C,. The results of the study showed that the highest removal rates for Lyngebia (62%, 83%, 74% and 95% at 22 ° C) while for Chlorella (71% and 71% at 32 ° C, 88% and 95% at 22 ° C) (95%, 98%, 99% 95% at 22 ° C) respectively, and Chlorella (95%, 95% and 98% at 32 ° C),. (96% at 32 ° C, 99%, 97% and 95% at 22 ° C), and Chlorella (99% at 22 ° C at 97 ° C) (32 ° C and 97% 97% at 22 ° C),. In the optical density test, there was an increase in the optical density of both algae halves during the experiment.
