dc.description.abstract |
The leather tanning industry or tannery, mainly in the small and medium scale (SMEs), is not
environmentally friendly. Limited capitals drive the SMEs-scale tanneries to dispose of liquid waste
directly into water bodies without proper treatment. It might cause serious environmental problems
due to the high content of COD, BOD, chromium, and dyes. Treatment of liquid waste using constructed
wetlands has been widely used because it is efficient, cheap, and powerful. This review discusses the
latest studies in the wastewater treatment of tanneries using phytoremediation techniques and
constructed wetlands and their potential applications in the SMEs tanneries.
