Abstract

Abstract

This research aimed to get the potential concentration of sago wastewater optimum with microalgae Chlorella sp to reduce pollutant wastewater sago.  Research was carried out by emplemented a Randomized Completely Design (RCD) with five treatments, namely: P₀ (1000 ml sago wastewater without addition of microalgae), P₁ (250 ml microalgae: 1000 ml sago wastewater), P₂ (250 ml microalgae: 800 ml sago wastewater), P₃ (250 ml microalgae: 600 ml sago wastewater), P₄ (250 ml microalgae : 400 ml sago wastewater).  Results showed that the concentration of sago wastewater and treated with microalgae Chlorella sp significantly reduced the COD, BOD, and TSS.  The best treatment is P₄ with COD 277,33 mg/L; BOD 125,33 mg/L; pH 7,04;  and TSS 83,66 mg/L.
