The Experimental Study of a New Sedimentation Tank

Through the research of close type separation device sedimentation tank (CTSDST) in static water test, it can be seen that change of effluent turbidity with time includes the two stages that turbidity diminishes quickly stage and turbidity decreases slowly stage in the static water precipitation. Meanwhile the results show that the sediment concentration of muddy water has little effect on the change of effluent turbidity with time and the effect of water purification is better than the sedimentation tank of no separation device. Moreover the CTSDST has many features such as energy saving, stable discharging water, small footprint, easy operation and maintenance, etc.
