This text is a brief review on the use of Advanced Oxidative Degradation Processes (AOPs) applied to treatment sewage and industrial domestic wastewaters. A quick introduction importance wastewater environment discussed, followed by benefits limitations techniques. Chemical fundamentals are focused generation hydroxyl radicals, hydrogen atom abstraction, electrophilic addition electrical transfer, radical-radical reactions. AOPs herein divided into two categories: homogeneous heterogeneous....
Using low cost materials, tubular photo-bioreactors type bubble column were built for microalgae cultivation. Six factors/two levels Taguchi orthogonal array (L8) was adopted to identify the input variables with greatest influence on oil accumulation by Chlorella minutissima. The function desirability used simultaneously analyze process attain maximum biomass concentration and lipid content. microalgal submitted acid simultaneous esterification transesterification reactions using homogeneous...
The present work evaluates the bioremediation potential of microalgae Chlorella sp. cultivated in industrial wastewaters a metallurgy facility for CO2 fixation. Its growth was investigated experimentally and rate determined based on different dilutions. Taguchi's experimental design carried out values found laboratory were compared to those mathematical model adjusted rate. Process efficiency evaluated reduce organic load, nutrient consumption, cell count during initial final stages via...
Microcystis aeruginosa (M. aeruginosa) is the dominant cyanobacterial species causing harmful algal blooms in water bodies worldwide. The release potent toxins and pose severe public health hazards to bodies, animals, humans who are contact with or consume this water. interaction between M. heterotrophic bacteria thought contribute development of blooms. This study strives provide a specific answer whether quorum sensing also potential mechanism mediating different strains/species expression...
This work evaluated the efficiency and systemic application of heterogeneous photocatalytic degradation for dairy wastewater under advanced oxidation process (AOP) utilizing solar radiation immobilized ZnO as measured by total organic carbon (TOC). The AOP system consisted a semibatch reactor glass tank operated with an initial volume 3 L wastewater. was on metal plate mm used catalyst bed. Evaporation rate considered when effective determined. utilized Taguchi’s 8 orthogonal array. entry...
A total of 8 assays was conducted to study the influence different variables namely, light intensity, CO2 level, NaNO3 concentration and aeration rate, on cultivation marine microalgae Chlorella sp. enhance biomass feedstock availability for biodiesel. The experiments were designed using a Taguchi L8 experimental array set at two levels operation, having intensity (0.85 14.5 klux), (5 10%), (0.025 0.075 g L-1) rate (3:33 1.67 vvm) as independent considering productivity lipid content...
Leachates exhibiting an unstable ratio of biochemical oxygen demand (BOD) and chemical (COD) approximately 0.45 are typical new landfills in the City Cachoeira Paulista, Brazil. Although organic matter portion is bio-treatable, presence refractory leached material requires unconventional effluent-treatment processes. Leachate treatment with ozone oxidation, ferric ions, acts as catalyst formation hydroxyl radicals. Ozone was obtained by corona-discharge from high-purity O2 gas. The performed...
This study presents results from an application of Photo-Fenton process for organic-load reduction in dairy effluents. Process efficiency was evaluated terms percentage dissolved organic carbon, chemical oxygen demand, and biochemical demand (DOC, COD, BOD, resp.), whose initial values were <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" id="M1"><mml:mn>1658</mml:mn><mml:mo>±</mml:mo><mml:mn>145</mml:mn></mml:math> mg O 2 L −1 ,...
The advanced oxidation process was conducted using the Design of Experiments in this work. Initially, Taguchi’s Orthogonal Array L16 (Photo-Fenton and Ozone) applied, with which it obtained 29.07% TOC removal. Then, optimized Photo-Fenton RSM, thus achieved highest percentage removal= 54.68%. This condition is associated a mass ratio hydrogen peroxide ferrous ions eight, corresponds to 47,8g H2O2 5,95g Fe+2.
Advanced oxidative processes (AOP) are an important alternative in the treatment of industrial effluents. Several studies literature report that kinetic profile organic matter oxidation presents behavior typical pseudo-first-order reactions. Recent work indicates a conversion rate two phases: (1) rapid initial phase described kinetics and (2) decelerated as pseudo-first order. Previously published proposed empirical stochastic model reproduced these behaviors. In present study, we found...
There are several studies in this same sense aiming to develop new processes and technologies minimize the volume toxicity of effluents generated by chemical industries. Currently, technology advances effluent residues treatment is based on environmental sustainability (residual reuse) degradation pollutant substances with easier natural degradation. Technology has improved, Advanced Oxidation Processes (AOPs) for instance, being generation hydroxyl radicals as oxidant agent, seems have...
