Liquid dairy manure is applied with irrigation water or injected into the soil, as well as being used for the production of biogas. One of the problems facing dairy operations is the slurry manure transportation and pumping through pipelines to distant locations of the farm, especially when the sand content (used as bedding material) increases. In this study, rheological properties of sand-laden dairy manure (SLDM) including total solids (TS%), density and apparent viscosity were determined at four levels of manure solids (7, 10, 13 and 16 %TS) as well as the liquid manure taken from a manure separator tested at shear rates of 1.76 to 225.28 using a concentric cylindrical rheometer. Effect of temperature on the apparent viscosity at five levels (10, 21,... |
