| description | Phytoremediation employs plants to remove contaminated soil and wastewater. The
effluents from aquaculture has large amount of suspended solids and enriched with
nitrogen and phosphorus in aquatic ecosystems. By using conventional wastewater
treatment to treat fishpond wastewater, the cost is expensive to run and maintain. The
performance of phytoremediation by using macrophytes, such as Lemna sp. and
Spirodela sp., are evaluated on treatment of fishpond wastewater. The duckweeds
were fed with wastewater from Catfish production facility. The objective was to
determine the nutrient update and its effect towards biomass. 4 pond rigs were set up
to study. They were Spirodela sp., Lemna sp., mix (Lemna sp. and Spirodela sp.) and
control (without plant). The water quality was monitored as well. The treatment by
phytoremediation was done in raceway pond rig for 2 weeks. The efficiency of
phosphate removal was 89% and 85% by Lemna sp. and Spirodela sp. respectively.
Spirodela sp. reduced nitrate concentration to 3.6 mg/L, while Lemna sp. managed to
reduce to 7.9 mg/l. Spirodela sp. archived 89.0% in phosphate removal efficiency
compared to that of Lemna sp. at only 85.1%. Lemna sp. and Spirodela sp. reduced
turbidity from 16.2 ± 4.0 NTU to 3.2 ± 2.4 NTU in just 6 days. However, both Lemna
sp. and Spirodela sp. did not change much in pH value. COD volatile solids of
fishpond wastewater. In overall, Lemna sp. and Spirodela sp. were good for nutrient
removal, improve water quality and growth of biomass. |
