    (WOLKITE UNIVERSITY, 2022-12) ABDELWAHAB FEYID; AWOKE ABEJE; HABTAMU TESFAWN; SHERAF ABALULESA,; TAREKEGN YILMA,; TOLOSA MENGISTU,; ZEWDIYE YIZEZEW,
    Pulp and paper industry is considered as one of the most polluting industry contributing 100 million kg of toxic pollutants that are being released every year in the environment and more than 260 chemicals have been identified in effluents, which are produced at different stages of paper making in pulp and paper industry. The pulp and paper industry is typically associated with pollution problems related to high BOD, COD, toxicity, AOX, color, suspended solids, lignin and its derivatives and chlorinated compounds. Although numerous studies have looked ways by various researchers to remove COD, BOD, color etc. of pulp and paper effluents, the problem still persists. Number of microorganisms including bacteria, fungi and algae has been implicated to degrade the xenobiotic compounds present in pulp and paper mill effluent. The aim of the current review is to overcome the limitations of waste water treatment method currently used in pulp and paper mill to be of cost benefit and to be able to fulfill the environmental protection requirements.
