Tricking flow nickel treatment for wastewater: An investigation on selective operating parameters

Abstract

Tricking filters works on the principle of attached growth processes. The biological slime layer is grown on the support and effluent is passed over it. Generally it is used for removal of organic matter. The tricking filters have been used successfully by many researchers for removal of variety of pollutants due to its simplicity, and less space requirement. In current investigation the trickle bed was prepared on stone support by growing biological layer. The studies were carried out to study effect of flow rate, initial concentration; slime layer preparation time and fruit peel concentration. It was observed that the time required to reach exhaustion concentration decreases with flow rate, initial concentration and preparation time. There exits optimum value beyond which the increase in the slime layer preparation time and fruit peel concentration doesn't have significant impact on removal.
