Effect of pretreatment of biosorbent in biosorption: A comparative study

The textile industry generates large amounts of wastewater with strong BOD/COD and salt load, which are often seen in dark colour. An alternative treatment for this type of wastewater is the biosorption, where it involves a passive uptake of both the organic and inorganic compounds, including dye or...
