Description:
Bio-sludge from a wastewater treatment plant could be used as an adsorbent of vat dye from textile wastewater. Resting bio-sludge gave a higher adsorption capacity than dead bio-sludge. The resting bio-sludge from a textile wastewater treatment plant gave relatively high COD, BOD"5 and dye adsorption capacity of 364.4+/-4.3, 178.0+/-9.0 and 50.5+/-1.3mg/g of bio-sludge, respectively, in synthetic textile wastewater containing 40mg/l Vat Yellow 1. Another advantage of the bio-sludge was that, after washing with 0.1N NaOH solution, it was reusable without any activity loss. Through treatment with a sequencing batch reactor (SBR) system, both organic and dye in STIWW could be removed. The maximum dye (Vat Yellow 1), COD, BOD"5 and TKN removal efficiencies of the SBR system under an MLSS of 2000mg/l and an HRT of three days were 98.5+/-1.0%, 96.9+/-0.7%, 98.6+/-0.1% and 93.4+/-1.3%, respectively. Although, the dye and organic removal efficiencies of the SBR system with real textile wastewater were quite low, they could be increased by adding organic matters, especially glucose. The dye, COD, BOD"5 and TKN removal efficiencies of the SBR system with glucose (0.89g/l) supplemented textile industrial wastewater were 75.12+/-1.2%, 70.61+/-3.4%, 96.7+/-0.0%, and 63.2+/-1.1%, respectively.
