The Defense Style Questionnaire (DSQ) is a self-report questionnaire and it revealed four factors upon factor analysis in previous study. Each was presumed to be group of defense mechanisms that we called style due substantial but limited validity. Further validation the DSQ tested this second study by correlating 156 subjects' responses with their scores on Mechanism Rating Scale (DMRS), which judges rated from videotaped clinical assessment interview. There were significant positive...
Wastewater treatment facilities use secondary to stabilize the effect of discharged effluent on receiving waters by oxidizing biodegradable organic matter and reducing suspended solids nutrients. The process was never specifically intended remove trace quantities xenobiotics, such as endocrine-disrupting compounds (EDCs) pharmaceuticals personal care products (PPCPs). Nevertheless, European studies performed at bench-scale or small have demonstrated that a critical minimum retention time...
Full‐scale ultraviolet (UV) light and chlorine disinfection systems were operated in parallel using nitrified partially denitrified tertiary treated wastewater effluent. A UV dose of 75 mW · s/cm 2 reduced the concentration fecal coliforms, enterococci, streptococci, MS2 bacteriophage, poliovirus by four logs. higher was needed to reduce heterotrophic plate count (HPC) logs achieve a total coliform value ≤2.2 MPN per 100 mL within consecutive 7‐day period as required most restrictive...
The feasibility of the membrane bioreactor (MBR) process for water reclamation was studied. Process evaluation based on following: literature review MBRs, worldwide survey and preliminary costs estimates. have shown that MBR offers several benefits over conventional activated sludge process, including: smaller space reactor requirements, better effluent quality, disinfection, increased volumetric loading, less production. can exist in two different configurations, one with low-pressure...
ABSTRACT There is interest in treatment processes that can both contribute to pathogen removal and provide effective pretreatment for reverse osmosis (RO) potable reuse systems. The most familiar train employs micro-/ultrafiltration along with cartridge filters (CFs) upstream of RO. However, there are some applications which other pre-RO processes, such as membrane bioreactors (MBRs), desirable. In cases, more research needed on MBR an RO process. addition, although CFs widely used, the...
Abstract Literature on ozone inactivation of Cryptosporidium was critically reviewed and analyzed. A set criteria established for selecting data from diverse sources experimental protocols with the objective compiling comparable data. Several kinetic models were evaluated ranging 4-parameter Hom “Power Law model to single parameter Chick model. No gave a “best fit” all sets. On case-by-case basis, included 3-parameter incomplete gamma Horn model, 2-parameter Chick-Watson one Temperature...
Abstract Water quality, in combination with design and operational data collected from multiple studies, was assessed to benchmark the performance of ozone‐biologically active filtration reuse applications. A total 149 contaminants emerging concern, representative categories chemical structures, were prioritized systematically compared elucidate apparent differences removal capabilities as affected by factors such influent water matrix, ozone‐to‐organic carbon ratio, empty bed contact time,...
The water–energy nexus has motivated water industry professionals to maintain performance goals with less energy input and fewer greenhouse gas (GHG) emissions. This article investigates protocols, methodologies, tools for GHG emissions control tracking that are adaptable or specifically developed use within the urban cycle. Although many operational energy‐minimization strategies available, real‐time near monitoring reporting of not yet widely sector. Additional study is warranted obtain a...

Climate change and urbanization pressures in parts of the world characterized by water scarcity have strained resources to point that many purveyors must operate within more a closed urban cycle using alternative sources while continuing protect public health.
