  • Soil Separates: Classification and Characteristics

    The texture of a soil horizon is an almost permanent character. The size of particles in mineral soil is not subject to readily change. Thus, a sandy soil remains sandy and a clay soil remain a clay. Texture cannot be altered and thus is considered as basic property of a soil.

    the PEP-soil mixture causes the PEP to coagulate and cling together. Later, water separation via hydroclone or screening will separate the soil from the PEP. Sobvent separation from water could be accomplished by distillation at a later time. Dry screening can separate PEP from soil, as long as it is of different particle size from the soil.
