High concentration of toxic compound in palm kernel wastewater will lead to harmful
effect to consumer when the wastewater discharged into water sources. Immobilized
microalgae have been introduced as alternative in removing nutrient from wastewater.
Hence, this experiment conducted using immobilized Chlorella vulgaris to remove toxic
compounds from palm kernel wastewater. In this experiment there were 5 treatments
which are blank beads (without microalgae), 1.0 beads/mL, 1.5 beads/mL, 2.0
beads/mL and control (no beads) were tested in 600ml of palm kernel wastewater.
Results showed that the toxic compound concentration decreased within 48 hours.
Removal percentages of TAN and NO2-N concentration were up to 97.61% and
31.98% using 1.0 beads/ml treatment. On the other hand SRP concentration reduced
up to 50.79% using 2.0 beads/ml compared to other treatments. This shows that
immobilized Chlorella vulgaris is an effective method in removing nutrients from palm
kernel wastewater.
