ABSTRACT Technical feasibility of an ion exchange process for removal and recovery lead present in battery manufacturing wastewaters is demonstrated. In absence aluminium ferric species, quantitatively removed recovered (≈90%) from the neutralised after elution on natural zeolite clinoptilolite. Control pH to 5.5-6 necessary minimise degradation exchanger material. Throughput volumes exceeding 2,700 bed (BV) (flowrate: Fexh10 BV/h) obtained, when initial Pb concentration 4 mg/L, with metal...
The beer brewing process is one of the most polluting industrial processes, generating a huge amount wastewater effluent and solid wastes (i.e. spent grain yeast), which must be disposed or treated in least costly way to meet strict discharge regulations set by government entities. Particularly, grain, leftover malt adjuncts after mash has extracted sugars, proteins, nutrients, can constitute as much 85 % brewery’s total by-product. However, sustainability hallmark craft industry therefore...
The oxidation of 10 nonionic surfactants (6 alcohol ethoxylates and 4 alkylphenol ethoxylates) by Fenton H2O2/UV processes was investigated in synthetic (deionized water) real aqueous matrices, i.e. secondary effluent from municipal wastewater treatment plant groundwater. Batch tests were carried out to assess the optimal dosages reagents leading total removal surfactants. Regardless specific surfactant, both treatments solutions containing one single surfactant (C0=14 mg l(-1)) always...
Fat, oil and grease (FOG) recovered by the oil/water separator of a wastewater treatment plant (WWTP) were sampled, characterized, activated converted into biofuel. Free acids (50-55%) fatty soaps (26-32%) not only composed main components, but they also easily separable from starting waste. The respective free acid profiles gas-chromatographically evaluated, interestingly verifying that had different profile (mainly oleic acid) with respect to soapy fraction (saturated dominant). inorganic...
Batch and column tests were conducted to compare the efficiencies of three Fenton‐like systems in degradation chlorobenzene. In investigated systems, iron powder was source Fe2+ ions, either Fe3+ or Cu2+ added order enhance process. Optimum pH concentrations Fe3+, hydrogen peroxide assessed by treating synthetic chlorobenzene solutions both batch mode, thus achieving minimum residual concentration conditions means then applied treatment real chlorobenzene‐contaminated groundwater. Results...
ABSTRACT Laboratory scale investigation has been carried out for the optimization of a new process separation and recovery Pb/Fe species from automobile battery manufacturing wastewaters. The innovation, based on ion exchange, allows mentioned by use commercial weak anion resin (Duolite A7 Rohm&Haas Co, USA), as selective sorbent ferric species, cation with carboxylate functionality (Purolite C106 Purolite Co.,UK) removal lead species. Cl-form was eluted real wastewaters (pH 3; Fes= 4BV/h;...
The paper reports the results of a laboratory-scale investigation aimed at evaluating performance periodic biofilter with granular biomass (SBBGR) for treating leachate coming from mature municipal landfill. show that SBBGR was able to remove roughly 80% COD in leachate. remaining 20% were, therefore, presumably owing presence recalcitrant compounds. Ammonia removal efficiency low because high salinity and inhibitory compounds investigated process characterised by very sludge production...
Titanates may be selectively used as inorganic adsorbents for heavy metal ions owing to their stability and fast adsorption kinetics. Nevertheless, the synthesis of such materials usually requires extreme reaction conditions. In this work, a new titanium-based material was rapidly synthesized under mild laboratory The obtained amorphous hydroxo titanate tested sorption through kinetic equilibrium batch tests, which indicated that had high rates capacities towards Cu(2+), Ni(2+) Pb(2) ions....
The photochemical degradation of two azo and anthraquinonic dyes was performed using potassium peroxymonosulphate (Oxone®) activated by UV radiation. fast decolourization all observed within 6 min irradiation, with corresponding dye decays higher than 80%. kinetic rate constants the dyes' decay were determined, along energetic efficiency treatment, taking into account influence a few anions commonly present in real wastewaters (i.e., chloride, nitrate, carbonate/bicarbonate phosphate ions)....
Fenton oxidation of the nonionic surfactant Brij 35 was enhanced by effect 1,4-hydroquinone adsorbed on granular activated carbon (GAC). The procedure allowed 90%–94% removal after 24 h at pH=2.7–3.0, using 97 mg g−1 hydroquinone GAC and concentrations surfactant, H2O2, iron (either Fe2+ or Fe3+) of, respectively, 1300, 450, 9 L−1. In absence hydroquinone, with same concentration conventional process required 300 L−1 Fe(II) to obtain 85% 35. Quinone-loaded effectively recycled until...
