To investigate the adsorption capacities of locally available low cost bio-adsorbents like  neem leaves, orange peels, peanut hulls and coconut coir pith powders to remove colour in a textile industry wastewater, experiments were performed.  The experiments were conducted at pH of 7 with different process parameters like adsorbent dosage,  temperature,  contact  time  and  agitator  speed  using  batch  adsorption  method.    From  the  experimental results,  the  maximum  colour  from  the  textile  industry  wastewater  was  obtained  at  an  optimum  adsorbent dosage of 350 mg, an optimum contact time of 73 min., an optimum temperature of 330 K and an optimum agitator speed  of  650  rpm. Further,  from  the  validation  experiments,  it  was  found  that  the  maximum  colour  removal percentage in textile industry wastewater is about 75.2%, 78.3%, 86.6% and 81.7 % respectively for neem leaves, orange peels,  peanut  hulls  and  coconut  coir  pith  powders.    This result was higher than the results obtained by different process parameters for various bio-adsorbents. Finally, from the results of adsorption study, it was concluded that bio-adsorbents used as a coagulant for removing the colour from textile industry wastewater especially peanut hulls powder because of its higher adsorptive capacity than other bio-adsorbents used in this study.
