Adlay is a cereal that has been used as food, but its use still limited. consists of high starch content, native adlay low water absorption capacity and other functional properties. The characteristics can be improved; some them are modified into porous starch. This study aimed to define granules improve the physicochemical properties by synergic modification microwave heat treatment (MHT) ozon...

The aim of this study was to investigate the feasibility of two decontaminating processes, ozonation and electrocoagulation, to decolorize wastewater generated by humid finishing leather production. With the objective to determine if one or both process could remove color, benchscale experiments were conducted with three different colorants, representative of the main dye groups: di-azo (CI Dir...

We hypothesized that exposure of healthy humans to ozone at concentrations found in ambient air causes both ozonation and peroxidation of lipids in lung epithelial lining fluid. Smokers (12) and nonsmokers (15) were exposed once to air and twice to 0.22 ppm ozone for four hours with exercise in an environmental chamber; each exposure was separated by at least three weeks. Bronchoalveolar lavage...

An ozonation pilot plant was installed at the Montréal Urban Community Wastewater Treatment Plant (MUCWTP) to assess the feasibility of employing a full scale ozone disinfection system. Wastewater characteristics such as turbidity, COD, TOC, BOD, pH, ORP and suspended solids were monitored to assess their effect on ozone disinfection. Fecal conforms (FC) were used as indicators to measure disin...

The research in this Thesis has been mainly performed at the research group Trataguas, from the Departamento de Ingeniería Química y Química Física of the Universidad de Extremadura. It is a part of an extensive research program on the elimination of emerging contaminants (ECs) in water through the application of advanced oxidation processes (AOPs), being developed by the Trataguas group and fi...

Photocatalytic oxidation/ozonation of a mixture eight pharmaceuticals added to secondary effluent, SE, an urban wastewater treatment plant has been studied using TiO2 supported on commercial Al2O3/SiO2 ceramic foams. As radiation source UVA LEDs (365 nm) or solar was used. Pharmaceuticals were at high (1 mg L−1 each) relatively low (50 μg concentration, contributing 25% and 1.5% the initial TOC...

Catalytic effects of cupric ion (Cu2+) and zero-valent copper (Cu0) on ozonation in aqueous solution were discussed this research using 1,4-dioxane as a radical probe. Ozonation with Cu0 enhance...

Ozonation was investigated as a potential post-treatment step for biologically treated landfill leachate to enhance the biodegradability and observe the influence of the initial organic matter concentration and pH. Changes in COD, UV absorption at 254 nm (UVA254) and BOD content were measured during and after ozonation, and the ozone utilisation efficiency at different conditions was calculated...

The double bond-to-ozone reaction stoichiometry was quantified for ozonation of several environmentally relevant unsaturated fatty acids and monoterpenes in saturated hydrocarbon solvents. Olefins with initial concentrations from 30 microM to 3mM were injected in a solvent (n-hexadecane, nonane, or cyclohexane) while an ozone-oxygen mixture was slowly bubbled through the solution. The number of...

this experiment was carried out at agricultural research station of gorgan during summer 2006 to study the effects of corn and green gram intercropping on forage yield, and weed biomass. the experimental design was rcbd with twelve treatments and four replications. a local green gram and corn single cross 550 were the crops employed. the experimental treatments consisted of sole corn and sole g...
