TEKNIK PEMANENAN MIKROALGA NANNOCHLOROPSIS SP. YANG DIKULTIVASI DALAM MEDIA LIMBAH CAIR KARET REMAH DENGAN FLOKULAN ALUMINIUM SULFAT
ABSTRACT: This study was aimed
to determine the best dosage for harvesting algaeusing Aluminium Sulfat. This
research done by harvesting microalgae Nannochloropsis sp. which cultivated in
the medium crumb rubber industrial wastewater (75% v/v) in an open reactor with
a working volume of 5L for 8 days with flocculation methode using aluminium
sulphate Al2(SO4)3[H1] in dose of 50 , 100, 150, 200, 250, 300 mg/L, and 200
mg/L NaOH as a comparison (control). The results showed that microalgae
Nannochloropsis sp. [H2] in the culivated medium crumb rubber industrial
wastewater which was harvested using dose 150 mg/L of the flocculant agent
aluminium sulphate Al2(SO4)3[H3] by cell density 4055 x 104 sel/mL has the
highest flocculation efficiency totalling 94,55%, dry biomass 0,7060 g/L, and
oil content 23,24%.
