To characterize the fouling potential of RO feed water the Silt Density Index (SDI) and the Modified Fouling Index (MFI0.45) are commonly applied. SDI is applied worldwide for many years on a routine basis by operators since it is a simple and cheap test. Unfortunately, the SDI has ...
Fig. 1: Apparatus for Measuring the Silt Density Index Procedure Assemble the apparatus as shown in Fig. 1 and set pressure regulator at 207 kPa (30 psig). Before installing the membrane filter, flush the water to be tested through the apparatus to remove entry contaminants. For samplin...
Adopting a density control strategy, the fully mixed and cured soil was incrementally injected into the PVC mold in three separate layers. After each injection, a vibration procedure lasting one minute was implemented to effectively eliminate air bubbles within the mixture and to enhance the ...
wet density, dry density, liquid limit, plastic limit, and plasticity index were incorporated as inputs for the model development. Later it was concluded that the developed hybrid model (ANFIS-FF) showed good prediction accuracy in terms ofR2(0.900) for liquefaction prediction. Overall, the propo...
Audible alertsnotifies the operator at the end of the silt density index test as well as if any errors have occurred. Clear, easy to read LCD displayprompts the operator through the test procedure and displays current test data while silt density index tests are underway....
·nSiO2yields a substantial amount of fibrous material that permeates the stabilized soil, filling voids and augmenting the soil’s density and structural integrity. However, as the content increases, the diminished space for hydration reactions, resulting from the filled voids, impedes further Na2O...
The dry density of the specimens was controlled to be 1.67 g/cm3. The changes in axial stress during the test are shown in Figure 3. The cyclic stress ratio (CSR) is used to study the effect of stress level on permanent strain, which is defined as Equation (1) [46]. 𝐶𝑆𝑅...
In a two-year study with a cereal rye (Secale cereal) cover crop, bulk density was decreased by 3.5% compared to the no-cover crop treatments [8]. Cereal rye cover crop can also quickly and significantly change the aggregate stability of the soil, as shown in a study by Steele et al...
Superimpos- ing and extrapolating the straight lines along the linear part of the anodic and cathodic polarization curves were utilized to acquire the electrochemical characteristic parameters, comprising corrosion current density (icorr) and corrosion potential (Ecorr). The specimens were subjected to 3...
