Evaluating Leachability of Residual Solids from Hydraulic Fracturing in the Marcellus Shale
… salt, radionuclides, and heavy metals which form residual solids during storage and treatment. The purpose of this research was to characterize the residual solids from hydraulic fracturing operations in the Marcellus Shale to predict the leaching behavior of select elements in disposal …

Evaluating Leachability of Residual Solids Generated from Unconventional Shale Gas Production Operations in Marcellus Shale
… off-site, resulting in significant generation of residual solids. These are either buried on site or are disposed in lined landfills. The objective of this study was to determine the levels of heavy metals and other elements of concern that will leach from these residual solids when placed in …

GENERATING BIOENERGY AND HIGH-VALUE PRODUCTS FROM HIGH SALINITY FOOD WASTE
… glycerin sludge from biodiesel production), and residual solids from VFAs separation after dark fermentation of food waste. The investigations were conducted using batch and semi-continuous systems in mesophilic conditions (35°C). Methane (CH4) potential tests were conducted to determine the …

Evaluating the Leachability of Elements from Residuals Generated by Hydraulic Fracturing in Marcellus Shale
… purpose of this research was to characterize the residual solids produced from hydraulic fracturing operations in the Marcellus Shale region. Four field samples were evaluated: drilling mud, treated sludge from the chemical treatment of process water, solids from the gravity settling of produced …

Effect of mean cell residence time on the acid hydrolytic assist activated sludge process
Handling and disposal of residual solids from wastewater treatment plants is an expensive and difficult task. The acid hydrolytic assist activated sludge process is one method of minimizing sludge production from a biological wastewater treatment process. Acid hydrolysis of waste sludge involves pH …

Factors Affecting Starch Conversion to Ethanol in Dry Grind Corn Process
… in higher ethanol concentrations and lower final residual solids. Resistant starch content for starch samples with 30% and 0% amylose decreased or remained similar after liquefaction and decreased further after SSF, for all four enzyme treatments. Four commercial corn hybrids with similar starch …
