In this study, kaolin from Wallan village, Mon State was activated to prepare low cost adsorbent for removal of colour and specific organic pollutants from the wastewaters. The removal efficiencies of kaolin were firstly investigated by treating the effluent with natural kaolin using various dosages of kaolin (3 to 9% wt/v) and different contact time (30 min to 150 min). Then the effects of combined mechanical and thermal activation (from 100 to 600ºC), and chemical activation (2.5 to 5.5 M sulphuric acid) on the contaminant removal efficiencies of kaolin were examined. The physico-chemical characteristics of wastewater such as colour, turbidity, chemical oxygen demand (COD) and UV/Vis absorbance at 436 nm before and after treatment were systematically analysed. The collected wastewater is characterized by extremely high chemical oxygen demand, turbidity and solid contents, apart from low pH, unpleasant odor and dark brown color. The experiments showed that natural kaolin (NK) largely removed colour imparting contaminants than turbidity and COD from wastewater. Activating the NK by methods such as grinding, grinding and heating, acid activation decreased its colour removal efficiencies while its turbidity and COD removal efficiencies dramatically increased upon activation.Among the natural and activated kaolin samples, acid activation of kaolin enhanced its turbidity and colour removal efficiencies. The maximum turbidity and COD removalefficiencies of ~80% and ~60%,respectively were achieved with acid activated kaolin (4.5 M sulphuric acid) for 30 min contact time whereas those of ~17% and ~36%, respectively with natural kaolin for 150 min."}]}, "item_1583103108160": {"attribute_name": "Keywords", "attribute_value_mlt": [{"interim": "distillery wastewater"}, {"interim": "kaolin"}, {"interim": "mechanical and thermal activation"}, {"interim": "chemical activation"}, {"interim": "contaminant removal efficiencies"}]}, "item_1583103120197": {"attribute_name": "Files", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_access", "date": [{"dateType": "Available", "dateValue": "2020-12-21"}], "displaytype": "preview", "download_preview_message": "", "file_order": 0, "filename": "24.pdf", "filesize": [{"value": "1.3 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_0", "mimetype": "application/pdf", "size": 1300000.0, "url": {"url": "https://meral.edu.mm/record/6960/files/24.pdf"}, "version_id": "e13df176-7844-4112-ac04-0f7916447ebc"}]}, "item_1583103131163": {"attribute_name": "Journal articles", "attribute_value_mlt": [{"subitem_journal_title": "Journal of the Myanmar Academy Arts and Science", "subitem_pages": "421-439", "subitem_volume": "Vol. XVI.
