Constructed Wetlands for Treatment Azo Textile Dyes Wastewater

Wetlands have long played a significant role as natural purification systems. Textile industry processes are among the most environmentally unsustainable industrial processes because they produce coloured effluents in large quantities polluting water. The aim of this study is to assess the performance of VFCWs to treat two different azo textile dyes with and without artificial wastewater for long periods of time through different operation modes such as contact and resting times and loading rates which has rarely been considered in previous research works.
