“…7). Yang et al (2017) reported that green algae or tide was effectively removed by using charged torrefied wood flour. It was suggested that the usage of an adsorbent produced via low temperature pyrolysis instead of the existing biomass adsorbent produced at high temperatures was a competitive alternative.…”

Potential application of Sembilang bamboo (Dendrocalamus giganteus) as a fuel source or an adsorbent was investigated, due to its large diameter, fast growth speed, and growth type. Samples of D. giganteus were carbonized at various temperatures, and then their physicochemical, fuel, and adsorption properties were analyzed and compared to the properties of Moso bamboo (Phyllostachys edulis), which is widely used as a raw material for charcoal in Northeast Asia. The volume, weight, and density of the D. giganteus samples were greatly reduced between carbonization temperatures of 200 °C and 400 °C. It is possible that the high levels of SiO2 and K in D. giganteus may cause a high electric conductivity value in Dendrocalamus giganteus charcoal, which is a poor fuel source because of its high ash content and low calorific value. The acidity of D. giganteus disappeared at a carbonization temperature of 400 °C and the pH of D. giganteus increased up to 10.3. The adsorption power of D. giganteus, in terms of iodine and methylene blue, was higher than that of P. edulis. Based on the results of this experiment, the proper utilization of Sembilang bamboo charcoal was suggested as a chemical adsorbent.

Due to global warming and abnormal climate, the incidence and scale of green tracts in rivers and water intake dam are increasing every year. Therefore, in this study, developed eco friendly positively charged Torrefied Wood Flour(TWF) coagulant by reusing wood damaged by blight as a natural material. In order to evaluate the effect of coagulant on water ecosystem, green algae contaminated water was collected and TOC showed high removal rate of 86% ~ 92% under 1% and 5% TWF C-PAM treatment condition. The NH 3 -N showed 53% removal efficiency. The average pH of the polluted water was 7.9 in the case of hydrogen ion concentration, and the pH of the treated water was in the range of 6.5 ~ 7.7, It was found to be suitable for water quality standards. In ecotoxicity tests, all the results of the experiment showed that both the number of green algae and that of treated water were not affected by the survival of the daphnia. Therefore, as a result of the analyzing, developed paste type TWF coagulants is considered to be able to remove algae using natural resources.
