Abstract

The textile industry generates huge amounts of wastewater which must be treated effectively in a bid to prevent water scarcity through re-use. In this chapter, the use of bio adsorbents from agricultural waste which included corn stalks, baggase and saw dust were used as bio adsorption carriers for textile water. Bio adsorbents with particle size ranging from 200-1000µm and surface area of 500-1100 g/m² were used to determine the effect of bio adsorbent size on textile wastewater treatment focusing on the total suspended solids (TSS) and the chemical oxygen demand (COD). Furthermore, the effect of bio adsorbent’s mass per unit volume with ranges between 1-5 g/L was also investigated on the impact from TSS and COD reduction. TSS and COD reduction by more than 70% were noted for increasing mass per unit volume in the textile water. However, an increase in the particle size of the bio adsorbent during textile treatment resulted in decreased efficiency of the TSS and COD reduction. Bio adsorbents present an attractive option which is easy to adapt for textile wastewater treatment.
