Treatment of Textile Dyeing Effluent Using Agriculture Waste Based Adsorbents - A Review

Objective: Removal of colour from the textile dyeing effluent is a major problem due to high tinctorial value, complex structure dyes, toxicity and presence metals in some dyes. The colouring matter has be removed before its discharge as it constitutes fraction pollution. spent dyes have disposal they Review waste based adsorption performance, economics involved options for adsorbents are objectives present work.
 Methods: Various techniques used removal including adsorption. Although activated carbon an ideal adsorbent, expensive treatment production regeneration costs. High cost led search alternate non-conventional adsorbents. Attempts been made by researchers use non-conventional, low-cost naturally occurring materials findings on literature survey authors’ experience.
 Findings: This review seeks give overview agriculture together with physical chemical processing needs, parameters mechanisms potential various adsorbent-adsorbate systems different effluents. Comparative studies conducted synthetic effluents well real also included. always concern industries. issue can addressed using which presented.
 Conclusion: gaps between practices research works identified highlighted along further needs mainly agricultural residues combustible. reused fuel boiler furnace that offset expenses extent.
