Dye-waste water treatment using banana peels as a substitute for activated carbon
Abstract
Use of various dyes in order to color the products as a common practice in composite knit industry. The presence of these dyes in water even at a low concentration is highly visible and undesirable. This study was carried out for the utilization of banana peels as adsorbent for the removal of dyes from waste water and to establish it as a standard waste water treatment process for composite knit industry. This experiment was performed in the laboratory at a small scale. The materials were obtained and treated for the removal of dyes at different amounts of the adsorbent, different Ph levels and contact time in a batch experiment.
The experiment showed that the removal percentage was 60-70% at Ph of 7 with a retention time of 120minutes. The optimum amount of the adsorbent was 1.5g/25ml
