Recent Papers on Industrial Effluents
This study offers a solution for reducing the environmental effect of wastewaters generated by the olive-oil industry. Olive-oil companies produce variable quantities of wastewaters, which require treatment for disposal or reuse. Today, regulations are becoming increasingly strict regarding the parameters measured in these effluents. In Spain, the resolution by the ...

Native, acidic pre-treated and composite clay efficiency for the adsorption of dicationic dye in aqueous medium
Environmental applications of composites have attracted the interests of researchers due to their excellent adsorption efficiency for pollutants. Native, HCl pre-treated clay and MnFe2O4/clay composite were investigated as an adsorbent for removal of methyl green from aqueous solution. The adsorption behaviors of dye onto native, HCl pre-treated and composite clays were studied as a function ...

Detection of bisphenol A in water samples using ELISA determination method
In order to study whether bisphenol A (BPA) can pass into drinking water from polycarbonate barrel and exist in the river and industrial effluent the indirect competitive enzyme-linked immunosorbent assay (ELISA) for the determination of BPA was established. The results presented an inhibition concentration at 50% absorbance (IC50) of 0.123 mg L−1, and the limit of detection (LOD) is 9.934 μg ...

Removal of Ni(II) from aqueous solution by using micellar enhanced ultrafiltration
To explore the potential of micellar enhanced ultrafiltration (MEUF) process for the treatment of industrial effluent, herein, we report the surfactant-based separation of a metal ion [Ni(II)] from the aqueous solution using two different anionic surfactants viz. dioctyl sodium sulfosuccinate (DSS) and sodium dodecyl sulfate (SDS). By following a systematic investigation, we utilized two ...

Factorial experimental design applied to adsorption of cadmium on activated alumina
The effective removal of heavy metals from industrial wastewater is a very important issue for many countries. This paper examines the removal of cadmium ions from aqueous solutions and industrial effluents by adsorption on activated alumina. The Brunauer–Emmett–Teller (BET) specific surface area, pore diameter and pore volume of the activated alumina were 156.7 m2/g, 58.4 Å and 0.23 cm3/g, ...

Removal of trivalent chromium from dilute aqueous solutions and industrial effluents using Emulsion Liquid Membrane technique
This paper reports a study of batch extraction of trivalent chromium from dilute aqueous solutions as well as electroplating and tannery effluent by Emulsion Liquid Membrane (ELM) technique. An experimental study was performed to optimise the pH of the aqueous external phase based on distribution coefficient of solute between aqueous external phase and organic (membrane) phase. The batch ...

Industrial pollution scenario due to discharge of waste water effluents along Dombivali Industrial Belt of Mumbai, India - a physico–chemical study
The paper deals with the study of physico–chemical parameters of industrial effluents discharged from different manufacturing industries situated along the Dombivali Industrial Belt of Mumbai, India. From the results it was observed that the conductivity, salinity, cyanide, TS and COD content of the effluents released from dyeing industries were maximum having the respective values of 23,287 ...

Cost benefit analysis of measures to reduce industrial effluent discharges
In an environmentally harmonized society the most cost effective measures to reduce the total effluent discharges should be taken into account. Generalised discharge values are presented for organic material and nutrients in this paper. Depending on conditions in the receiving water any of these parameters can be the determining factor for the eutrophication and oxygen demand. These parameters ...

Removal of phenol using mushrooms and immobilized polyphenol oxidase in a plug flow reactor
Phenols are toxic and hazardous pollutants, hence their removal from industrial effluents is important. In this study, edible mushroom particles, which are a cheap and natural source of polyphenol oxidase (PPO), were used directly for phenol removal in a plug flow reactor. Initially, 60% phenol removal was achieved, but this percentage decreased after a second use. When the reactor included PPO ...

Removal of Cd(II) ions from aqueous solution and industrial effluent using reverse osmosis and nanofiltration membranes
Industrial effluents loaded with cadmium have contributed to the pollution of the environment and health troubles for humans. Therefore, these effluents need treatment to reduce cadmium concentration before releasing them to public sewage. The purpose of the research is to study the major role of reverse osmosis (RO) and nanofiltration (NF) processes, which can contribute to the removal of ...

Optimisation of radiolysis of Reactive Red 120 dye in aqueous solution using ionising 60Co gamma radiation by response surface methodology
In recent years, employing radiation technology is gaining great interest in degradation of industrial effluents. In this work the possibility of using gamma irradiation to degrade Reactive Red 120 (C.I.292775) was explored. The effects of pH, dose of gamma irradiation and concentration of dye were examined and their interaction were also established based on their response. For the analysis ...

Trace metals: Inputs, sedimentation and accumulation in San Vicente Bay, Chile
The present study deals with sediment dynamics affecting sediment-associated metal distributions in an embayment system experiencing pollution from coastal industries. Sedimentary metal content may originate from diagenetic processes of foundation rock on the bottom, allochthonous minerals from natural sources, and metals from industrial effluents along the coast. The study presents experimental ...

Noble metal modified titania catalysts in the degradation of Reactive Black 5: a kinetic approach
The photocatalytic degradation of Reactive Black 5 (RB 5), a di-azo dye was investigated over M/TiO2 (M = Ag, Au and Pt) photocatalysts irradiated with UV and visible light. TiO2 was prepared by sol–gel technique (Syn-TiO2). Photodeposition of metal salt precursors over Syn-TiO2 was carried out so as to obtain 1 wt% of M/TiO2 catalysts. The photodecolourization and photodegradation reactions were ...

Water quality of a stream receiving industrial effluents, located in the Brazilian Northeast
Industries, as a source of pollution, have a considerable impact on water resources due to the diversity in the composition of their effluents. The Mussure Stream was chosen for this study because it flows across the industrial district of Joao Pessoa, in Northeast Brazil, and is the main receiver of liquid effluents, which are disposed into the stream almost exclusively without adequate ...

Microwave and Fenton`s reagent oxidation of wastewater
Abstract We compared two H 2O 2 oxidation methods for the treatment of industrial wastewater: oxidation using Fenton's reagent [H 2O 2/Fe(II)] and microwave irradiation. Both methods were applied to the treatment of synthetic phenol solutions (100 mg L -1) and of an industrial effluent containing a mixture of ionic and non-ionic surfactants at high load (20 g L -1 of COD). The effects of initial ...
