||Domestic laundry wastewater (DLWW) has been remediated with activated charcoal (AC).
The physico-chemical identities of AC (pH=6.4, moisture content=1.02%, ash content=12.4%, bulk density= 1.7g/cm3, iodine number=1332, methylene blue number=322 and fixed carbon=46.9%) that were established technically enhanced the adsorption potential and treatment of laundry waste.
DLWW was characterized (Physical, chemical, and organic nutrient demand) before and after treatment.
Physical parameters in terms of pH, color, turbidity, electrical conductivity, and total dissolved solids were significantly controlled by 50, 47.5, 97.7, 82.70 and 58.02% respectively. Chemical parameters; in terms of alkalinity, phosphate, nitrate, sulfate, fluoride, chloride and calcium were controlled by 46.71, 96, 58.33, 70.15, 97.18, 99.84 and 98.46% respectively. Heavy metals with respect to copper, cadmium, nickel, iron, manganese, chromium, zinc, lead, magnesium and potassium are 83.64, 98.33, 99.46, 73.44, 38, 96.8, 24.96, 95, 15, 20, 91.5 and 29.21 % treatments respectively while organic nutrient demands in terms of biological oxygen demand and chemical oxygen demand, achieving 91.5% and 29.21% respectively with world health organization (WHO) guidelines as standard. The sorption processes were strongly supported by two parameters adsorption models of Langmuir (R2=0.9679) and three adsorption model of elovish (R2=0.9690) than to two parameters model of freundlich (R2=0.8869).Deducing from the relationship between the three adsorption models, the overall processes are predicted to be exponentially homogenous in nature.
