Biological wastewater treatment methods are classified as suspended growth and attached growth. Activated sludge process and trickiling filters are examples of these types of methods. Removal of organic matter is main objective behind these treatment methods. In the present research wastewater from dye industries is treated by using trickiling filter. The trickilng bed was prepared by growing the microbial slim layer on the stone gravel filling. The dissolved oxygen, chemical oxygen demand and pH of the treated and untreated effluent was compared. In the present investigation about 75 percent of COD removal was obtained with 6 fold increase in dissolved oxygen.
Key words: Attached growth process, biological oxygen demand, dissolved oxygen, chemical oxygen demand.
