Analysis of color removal in the medium dye wastewater For the mixture of dyes and dye wastewater study, the true color level independent of hue was measured using the American Dye Manufacturers’ Institute (ADMI 3WL) tristimulus filter method.
This method is applicable to colored waters and wastewaters having color characteristic.
The decolorization of mixture of dyes and actual dye wastewater by Lysinibacillus sp. RGS was determined by measuring ADMI from the aqueous solutions.
ADMI removal percent (%) is the ratio between the removal ADMI value at any contact time and the ADMI value at initial concentration was calculated (25) as
follows:
