INVOLVEMENT OF BASALT TUFF AS A FLOCCULANT IN THE SEPARATION OF MICROALGAE MONORAPHIDIUM SP. BIOMASS

Abstract

For the first time, the paper considers the possibility of using basalt tuff as a flocculant for aggregation and sedimentation of the biomass of the green alga Monoraphidium sp. The sedimentation rate of algae biomass was analyzed when basalt tuff was added in concentrations of: 0.5 g/l, 1 g/l, 1.5 g/l, 2 g/l. The separation of settled biomass was carried out either by centrifugation or sedimentation. The percentage of separated cells from the fugat was determined. A scheme for the separation of algae biomass has been developed, which includes: the use of basalt tuff as a flocculant at a concentration of 2 g/l, the ratio of the culture liquid of algae and flocculant is 25:1, settling the mixture for 48 hours, separating the fugat.
