This work is intended to optimize the experimental conditions for the maximum oxidative degradation of hydroxypropyl guar gum by the coagulation and UV/H2O2/ferrioxalate complexes process. Optimal reaction conditions were proposed based on the chemical oxygen demand (COD) removal efficiency and UV_vis spectra analysis. ...
This work evaluated the performance of a dissolved air flotation (DAF) system for biomass recovery from the effluent of algal ponds used for sewage treatment in Northeast Brazil. Two different coagulants and effluent samples were tested following a random-factor experimental design (34–1–4 factors and 3 levels), in triplicate. Factor analysis showed that ...
The paper presents results of research on the removal of priority hazardous polycyclic aromatic hydrocarbons (PAHs) (anthracene, benzo[a]pyrene, benzo[b]fluoranthene, benzo[k]fluoranthene, benzo[g,h,i]perylene, indeno[1,2,3-cd]pyrene) from water in the coagulation and sedimentation process. Coagulants chosen for the analysis were ...
New strategies were herein applied for treating a cotton dyeing wastewater: coagulation/flocculation followed by Fenton’s oxidation – approach 1, Fenton process per se – approach 2, and Fenton followed by coagulation/flocculation – approach 3, aiming reducing chemicals consumption. Regarding the cost analysis, which is crucial for deciding on ...
In an effort to address the current arsenic drinking water requirements in Hungary, life cycle analysis (LCA) methodology was applied on two example arsenic removal technologies, coagulation-filtration and adsorption, from cradle to grave. ...
Hybrid microfiltration (MF)–ultrafiltration (UF) and hybrid coagulation–ultrafiltration membrane processes were investigated and compared for dissolved organic matter (DOM) reduction in the low turbidity raw water supply from Sri-Trang Reservoir, Thailand. The coagulation process was operated with 20 mg/L polyaluminum chloride (PACl) at pH 7. ...
At all pH values (7.5–7.8) and coagulant dosages (0.84–3.00 mg/L Fe) tested, the negative effect of phosphate on arsenic removal was also evident. ...
