The main objective was to reduce the  colour strength of the effluents.  The first method  was chemical pretreatment using oxidation and  reduction to destroy the conjugate double bonding  system of the chromophore structure. The other  method was the physical pretreatment using activated  carbon to adsorb the colourant.  The parameters  studies were chemical auxiliaries, colour strength,  conditions and types of dyestuff.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783844321654\"\u003e\u003ch3\u003eDye effluent treatment by physical and chemical process.\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783844321654","offer_id":39495933657181,"sku":"9783844321654","price":49.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/0af996cb-d33e-4555-b9aa-adc557246ae5.jpg?v=1757655447","url":"https:\/\/shop.autorenwelt.de\/products\/investigation-on-removal-of-residual-dyestuff-effluent-von-kanchana-luepong","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
