Abstract Use of various dyes in order to color the products is a common practice in composite knit industry. The presence of these dyes in water even at low concentration is highly visible and undesirable. This study was carried out for the utilization of orange peel as adsorbent for the removal of dyes from wastewater and to establish it as a standard wastewater treatment process for composite knit industry. This experiment was performed in the laboratory scale. The materials were obtained and treated for the removal of dyes at different doses. These materials also evaluated for different pH and contact time. This batch adsorption experiment was carried out for finding the effects of adsorbents amount pH and retention time on the removal of dyes from the wastewater. The experiment showed that the removal percentage was 60-70 at pH7 with a retention time of 120 minutes. The optimum dose amount of adsorbent was 1.5g25mL. The equilibrium adsorption behavior was examined by applying Langmuir adsorption isotherm model. The adsorption capacity of orange peel is low but comparable to the other available adsorbents.
