Pesticides and insecticides are harmful and toxic organic chemicals that are used for controlling pests and insects in agriculture, thereby considered as necessary evil. Agricultural wastewater, contaminated with such toxic pesticides, pollutes surface and groundwater. Pesticides are able to reach surface waters either directly or indirectly via the discharge of agricultural drainage water from...
Pollutants such as pharmaceutical products and pesticides are still present in treated water. Several of these compounds photoactive. The photodegradation eight organic pollutants was studied using listed advanced oxidation processes: UV/H2O2, UV/persulfate, Fenton, photo-Fenton UV/TiO2. results show that is most effective the first 10 min treatments simulated urban wastewater collected from lo...
Backgrounds and Objectives: Untreated leachate is discharging into the environment in the many countries of worldwide. Leachate treatment methods have not been unified so far due to variable composition of leachate. Moreover, the uncontrolled management of leachate, cause many environmental dissociates. The aims of this study apply the Fenton process to decrease the pollutants of Kerman leachat...
A influência do pH na degradação do fármaco diclofenaco (DCF) por processo foto-Fenton/ solar foi avaliada usando o complexo citrato de amônio e ferro(III) (FecitNH4). Embora a eficiência de degradação diminua com o aumento do pH (no intervalo de pH de 5 a 8), a concentração de DCF ficou abaixo do limite de detecção após 45 min de irradiação enquanto que 77% do carbono orgânico total foi removi...
The influence of iron species on amoxicillin (AMX) degradation, intermediate products generated and toxicity during the photo-Fenton process using a solar simulator were evaluated in this work. The AMX degradation was favored in the presence of the potassium ferrioxalate complex (FeOx) when compared to FeSO(4). Total oxidation of AMX in the presence of FeOx was obtained after 5 min, while 15 mi...
Background & Objectives: Entering LAS through the wastewater plant’s effluent to water resources causes taste and odor changes, aquatics death, oxygen transfer limitation, and disorders in water treatment processes. Therefore, the study objective was to determine optimum conditions for fenton oxidation process to remove linear alkyl benzene sulfonate from aqueous environments using taguchi meth...
Background and purpose: Wastewater olive processing industries have significant amounts of organic compounds resistant to biodegradation which are hazardous if not treated and discharged to the environment. Advanced oxidation processes such as Fenton process have been considered to increase and improve the biological degradability of this type of wastewater. Current study aimed at investigating...
