  7. Abstract:
  8. Water is the essence of life. On average, a human being consumes about 2 liters of water every day and it accounts for about 70% of the weight of human body and this alone reflects the importance of water for continuation of life. The production process in textile and dyeing factories as increasingly growing industrial units consume large amounts of water and consequently produce large volumes of wastewater. Such industries face environmental regulations on one hand and are unable to compete with foreign products on the other since the imported counterparts are low-priced. Therefore, finding a cost-effective and efficient solution for treatment of waste water and troubleshooting and modification of the chemical /biological treatment plant of the Ekbatan textile factory in order to increase the quality of effluent is of great importance. Vermifiltration is a novel technology, costeffective and environmentally friendly method that is used many countries worldwide for treatment industrial waste water. In this method, earth worms are used to reduce pollution of waste water. In the present study, Eisenia fetida earth worm is used for treatment of Ekbatan Textile Industry wastewater which is very diverse and dense. The results show a 56-68 percent reduction in COD, 62-75 percent reduction in BOD and 67-75 percent reduction in TDS. The results clearly demonstrate the effectiveness of the proposed method
