SUGARCANE BAGASSE ADSORPTION EVALUATION AND APPLICATION ON BOD AND COD REMOVAL FROM TEXTILE WASTEWATER TREATMENT

Without properly treated Wastewater released from textile industry contains organic and inorganic pollutants and causes environmental problems. Textile wastewater contains: BOD, COD, toxic heavy metals, organic and inorganic particle matter, colour and etc. The multi-component pollutions needs latest technology treatment. Butch adsorption process is one of the best selective unit operations for such treatment using organic waste material. Sugarcane bagasse was used for this experimental study in butch adsorption process. The variable affects the adsorption process are adsorbent dose changes 0.5 g to 2 g in 200mL sample, pH ranges 3 to 11 and retention time 3 to 7 days. The maximum BOD removed was 85% at 0.5 g, 3days and 8.32 dose, retention time and pH values respectively, and the maximum COD removed was 86% at 1 g, 3 days and 8.24 adsorbent dose, retention time and pH value respectively. Adsorbent dose, pH and retention time are significant factors on the competitive pollutant removal.
