COMPARATIVE STUDY ON REMOVAL OF HEAVY METALS FROM TEXTILE INDUSTRY WASTEWATER USING VARIOUS ADSORBENT
Abstract
The most important class of pollutants are the effluents (dyes) which are disposed directly to the river from the textile industries. Disposal of the effluents into the water streams or precious water resource must be avoided. However there are various treatment methods before disposal, which will not be effective in the removal of heavy metals. Adsorption is recognized as an effective and economic method for low concentration heavy metal wastewater treatment. In the adsorption process numerous adsorbents are available. The adsorbents used are banana peel, activated carbon produced from coconut shell. The adsorption process is done using column chromatography. In this project a comparative study is done in order to make a comparison between the removal efficiency of the various adsorbents. Some of the heavy metals which are present in even smaller amount will cause a greater pollution. This project is based on the various adsorbents which have greater influencing in the removal of heavy metals, namely copper and chromium. The dosage of adsorbents is about 10 grams, 15 grams, 20 grams which will create a situation of removing heavy metals. The adsorption process is done at the room temperature for about an hour for each adsorbent. The adsorption process is started with the initial concentration of 10 gram of each adsorbent and then gradually increased based on the removal percentage. At the end 25 gram of dosage is given beyond that which produces which produces heavy metals.
