Removal of disinfection by-product precursors by activated carbon and MIEX(R)
… (HPO), and transphilic (TPI) NOM was fractionated and subsequent DBP formation from these fractions was studied. Several new adsorptive materials (greensand, carbon nanotubes, iron impregnated activated carbon) were tested for DBP reduction potential. Reductions by the materials were poor …

Chloramine and MIEX control of disinfection by-products formed from an alluvial aquifer water source
Disinfection has been applied for centuries for disinfection process. The formation of disinfection by-products (DBPs) caused by disinfection become a main safety issue for the public health. Trihalomethanes (THMs) and haloacetic acids (HAAs) are two of the major classes in DBPs. In response to …

Assessing Biofiltration Pretreatment for Ultrafiltration Membrane Processes
An engineered biological filtration (biofiltration) process treating a nutrient-enriched, low-alkalinity, organic-laden surface water downstream of conventional coagulation-clarification and upstream of an ultrafiltration (UF) membrane process was assessed for its treatment effectiveness. The …

Understanding the nonaqueous partitioning of per- and poly-fluoroalkyl substances (PFAS)
… fate, including their environmental distribution, bioaccumulation in biota, and treatment process, is of particular interest. Soil acts as a reservoir of PFAS in the environment, serving as a secondary contaminant source for the vadose zone, surface water, groundwater, and biota. PFAS leaching …
