Flow behavior of industrial effluents in soils with different textures

Abstract

A capillary rise experiment was conducted by passing different organic industrial effluents [liquor distillery effluent (DE), cotton seed delinting plant effluent (CD), and sewage water (SW)] through soils with two different textures. The validity of Poiseuille's law was verified in the first time segment by a straight line relationship between wetting front rise velocity dz/dt and the inverse of the wetting front rise I/Z. The soil geometrical and transmission characteristics (e, G, r, X, and k) were estimated by a quick capillary rise (QCR) approach. The liquor distillery effluent was found to have the lowest flow velocity through both types of soils due to its lower surface tension higher viscosity and density than those of ordinary water. Due to the acidic nature, CD could not be used for irrigating the fields, whereas, SW was not found to have any harmful effects on its flow behavior in the soils.
