Completion report settling basins for irrigation return flow and fresh pack effluent Item Info

Sediment yield was monitored from seven fields in southern Idaho to determine the effects of crop type, soils, topography and other parameters. Regression techniques and application of the Universal Soil Loss equation were used in attempts to develop predictive procedures for sediment yield. Measured seasonal sediment yields varied from .34 to 37.0 tons/acre depending on the crop, soil type and field slope. Average sediment and nutrient removal efficiencies for farm settling ponds for an irrigation season varied from 69 to 93 percent for sediment and from 25 to 78 percent for phosphate and nitrogen. A mathematical model was developed as a tool for settling pond design and the model results verified with measured data. Water quality parameters of effluent from four potato fresh pack operations were measured and removal efficiencies determined on four settling facilities. Removal efficiencies of 70 to 90 percent for C.O.D., 63 to 99 percent for suspended solids and 13 to 80 percent for total nitrogen were measured.
