Fate and Treatability of Engineered Nanoparticles in Urban Stormwater
… is explored, and the influence of n-Ag on the treatability of co-pollutants is examined. Through the analysis of particle size distribution, it was noticed that metallic ENPs tend to aggregate initially, while extended turbulence in the system leads to disaggregation. Stormwater samples with …

Physicochemical and biological treatability study of textile dye wastewater
The textile industry discharges a highly colored wastewater characterized by high organic levels. Industrial wastewater with these characteristics can be harmful to receiving streams and municipal plants, and must be treated prior to discharge. In this project, a yam dyeing facility was studied …

Treatability of emerging contaminants in wastewater treatment plants during wet weather flows
… inflow into sanitary systems and the amounts and treatability of targeted pharmaceuticals. Stormwater is a known source of many contaminants and could mix with wastewater through stormwater infiltration and inflow (I & I). Several dry and wet weather series of samples were obtained from the city …

The Effectiveness of Multiple Redox Treatment Strategies on the Treatability of a High Strength Industrial Wastewater
The treatability of a high strength industrial wastewater, 9,000 mg/L as chemical oxygen demand (COD), by three sequencing batch reactor (SBRs) systems operated under alternating redox environments: anaerobic/aerobic (ANA), anoxic/aerobic (ANX), and aerobic was investigated. A synthetic wastewater …

Preservative treatment evaluation of five Appalachian wood species with four preservatives
… well documented studies of what has been termed "treatability". This work investigated and documented the treatability of five common and abundant Appalachian hardwoods vacuum/pressure treated with the four wood preservatives creosote, chromated copper arsenate (CCA), ammoniacal copper quaternary …

Biological Health Assessment of an Industrial Wastewater Treatment Facility
… the addition of nitrogen and phosphorus. The treatability of acetone and ethanol was studied through sOUR and batch testing to determine bacterial response to solvents. Both solvents were utilized by the microbes. The concentrations tested proved to be beneficial, not inhibitory. Ethanol and a …

Characterization and treatment of wastewater from blue crab (Callinectes sapidus) processing facilities
… highly variable daily and seasonal production. Treatability studies were completed on the process wastewater because discharge limits exist for TSS, Oil and Grease and in some cases BODs and ammonia. Settling and filtration studies were performed on these effluents. The organics and nutrients in …

The removal of phenols from oily wastewater by chlorine dioxide
Treatability studies were performed on oily wastewaters produced by petroleum and canning industries. Chlorine dioxide was used for the removal of phenolic compounds from these oily wastewaters. Most of phenolic compounds can be destroyed by chlorine dioxide within 15 minutes if CI02-to-phenol …
