عنوان انگلیسی Investigation of solid removal of the Cornell design tank by using submerged vanes
چکیده انگلیسی مقاله Many scientists have been studied on water quality and solid removal from Recirculating Aquaculture Systems (RAS), but the solid removal problem did not solve completely yet. This paper is based on experimental data on a cylindrical tank in diameter of 0.53 m and height of 0.17 m and inlet flow using six nozzles in 2 mm diameter to determine solid removal efficiency by comparison with some different scenarios. The results indicate that using submerged vanes on the bed of the tank may improve removal of solid particles. In this paper 10 different scenarios compared and some of them showed more effectiveness on solid removal. The number of submerged vanes in outer pyramid of the tank bed does not necessarily reduce amount of sediment discharge efficiency, and the location of each vane makes a special impact on the context of hydraulic conditions and solid removal as well. The experimental observations showed, the second scenario (12 submerged vanes in binary groups) and the third scenario (7 submerged vanes in 45º by the vicinity of the tank wall) have significant impacts on sediment discharge efficiency.
