| Abstract |
| The aim of this study was to investigate the nutrient and blue green algae removal using hybrid bead in the lake water. Hybrid bead is a composite bioadsorbent made by mixing sericite and chitosan. Therefore, hybrid bead has a variety of electric charges, so it has the advantage of removing nutrients and blue green algae that have various electric charges in the lake water. Hybrid bead removed successfully 90-96% of the nutrient and Chl-a in the lake water at the following optimal parameters: Temperature 25 °C, pH 7-8, mixing time 60 min, hybrid bead dosage 3 g/L. The relationship between TN, TP and Chl-a was highest obtained 0.999 and 0.9977, respectively. This indicates that nitrogen and phosphorus have a great influence on the eutrophication of rivers and harmful algal bloom. Hybrid bead is an eco-friendly blue green algal and nutrient remover that does not adversely affect the ecosystem. In addition, the cost is low and the efficiency is high, so it can be applied in the field. |
