APPLICATION OF FLOATING WETLAND FOR TREATMENT OF PAPER MILL WASTEWATER

Abstract

The wastewater from the paper mills is described by dark yellowish color, high amounts of COD, phenol, BOD, pH, TDS and lignin. This study concerns plants were vegetated in wastewater of paper mill by using different treatment named as T1, T2, T3, T4, T5 and T6.The examination was run in duplicated with the resulting treatment design (T1) T. domingensis + Tap water, (T2) Wastewater and T. domingensis, (T3) Wastewater + T. domingensis+ M40, (T4) Wastewater + T. domingensis +M8, (T5) Wastewater + M40, (T6) Wastewater + M8 in pot tests. As T. domingensis is an aquatic species, holds great potential to remediate contaminated water. In this study impact was seen on the effect on growth of T. domingensis and the level of toxicity in contaminated was estimated by using Fish Toxicity assay.
