The immobilization of microalgae is one of the techniques to treat textile dyes
wastewater. The objectives of the study were to assess the growth of Chlorococcum
sp. immobilised in alginate & Chlorococcum sp. in suspension in different
concentration of textile dye and to assess the reduction of pollution parameter of the
textile dye after treatment under laboratory conditions. In this study, Chlorococcum
immobilised in 1% alginate and Chloroccocum suspension were grow in different
concentration of textile dye wastewater (0, 10 & 50 mg/L) for 12 days. The growth
(chlorophyll a, carotenoid, dry weight) were measured on days 0, 2, 4, 6, 8, 10 & 12.
The pollution parameter (ammonia, nitrite, phosphate & colour) were measured on
day 0 & 12. The results showed that in Chlorococcum immobilised in alginate (50 mg/L
textile dye on day 12) have highest Chlorophyll a (1.48 mg/L) in comparison to
Chlorococcum suspension (0.14 mg/L Chl a). The highest reduction of pollution
parameter obtained in immobilised cultures grown in 50mg/L are 85.84%
(phosphate), 83.70% (nitrite), 91.25% (ammonia) & 93.28% (colour). In conclusion,
we found that Chlorococcum immobilised in alginate can treat textile dye better than
growth in cell suspension.
