Evaluation of Physical and Micromorphological Properties of Saprolites for Wastewater Treatment
Saprolite is defined as soft, massive, friable, isovolumetrically weathered bedrock that retains the fabric and structure of the parent rock (Pavich, 1986). It is the transitional material between hard rock and the solum and has characteristics of both the parent rock below and the soil above it...

| description |
Saprolite is defined as soft, massive, friable, isovolumetrically weathered bedrock
that retains the fabric and structure of the parent rock (Pavich, 1986). It is the
transitional material between hard rock and the solum and has characteristics of
both the parent rock below and the soil above it (Daniels et al., 1984). Saprolite
is currently being used for the on-site treatment and disposal of household
wastewater (Vepraskas et al., 1996) and storage of some radioactive wastes
(Vepraskas and Williams, 1995). Due to extensive housing development, suitable
soils for septic systems are being depleted (Schoeneberger et al., 1995). Thus, a
g reater demand is being placed on the use of saprolite for wastewater disposal
purposes.
The objectives of this study are (1) to study the physical and micromorphological
characteristics of different saprolites, (2) to study the saturated hydraulic
conductivity of different saprolites, and (3) to correlate the saturated hydraulic
conductivity with the physical characteristics and develop models to predict Ksat
for different type of saprolites for wastewater treatment. The hydraulic conductivity was carried out in the laboratory using metal core rings
(7.62 cm internal diameter x 4 cm long) and double-ring infiltrometer were used in
situ. To determine the physical properties, standard method is employed for the
particle size distribution, bulk density, particle density, total porosity, penetration
resistance, and water retention capability. Micromorphology and scanning electron
microscopy were used to observe the microfabrics. The pore size distribution
was analyzed using an image analyzer and pore shape was also determined. |
