Abstract
Spent Merox caustic (SMC) is a hazardous waste that is produced during the Merox desulfurization process in the petroleum refinery industry and should be treated before discharging to environment. In the present study, treatment of SMC was investigated by three methods including Fenton-like process, foam fractionation, and a combination of both processes. Immobilized TiO2/Fe0 on modified silica nanoparticles was used as a heterogeneous Fenton-like catalyst. The chemical and physical characteristics of the catalyst were determined using Fourier-transform infrared spectroscopy, X-ray diffraction, diffuse reflectance spectroscopy, thermogravimetric analysis, differential scanning calorimetry, and transmission electron microscopy techniques. The treatment performance of the combined method was measured as a cost-effective method with chemical oxygen demand (COD) removal percentage. The effect of parameters including pH, gas flow rate, surfactant type and concentration of hydrogen peroxide, catalyst, and chelate were investigated. It is found that the prepared heterogeneous catalyst has high activity for the treatment of SMC. In addition, the results showed that the combined method achieved 97.6 ± 0.5% COD removal, while the measured values for Fenton or foam fractionation methods alone did not exceed 85.5 ± 1% and 47.2 ± 0.4%, respectively. The advantage of combination process over foam fractionation was the use of an advanced oxidation process in the separating column to eliminate or reduce the secondary phase contamination load. Besides, the role of the column in the effective contact of contaminants with the rising bubbles improved the degradation performance of the proposed process and reduced the consumption of hydrogen peroxide by 46% compared to the Fenton-like method.

Abstract
Dyes are intensively used in textile and dyeing industries, and substantial volumes of organic wastewater with residual dye require treatment before discharges to public waterways. Flotation separation is an efficient and widely used method for the treatment of massive organic dye wastewaters. The key scientific problems for dye flotation separation lie in the mineralization transformation of dissolved dye to tangible flocs. In this work, a high-efficiency removal of hazardous azo dye Congo red (CR) from simulated wastewaters via metal ions chelation flocculation followed by flotation separation was proposed. It's demonstrated that CR can be chelated by the trivalent metal ions, including Al(III), Fe(III), and its mixture to form hydrophobic flocs, and then the flocs were efficiently removed via flotation in a microbubble column. The effects of chelation flocculation and flotation separation conditions on the removal efficiencies of CR, COD, and chromaticity from CR simulated wastewaters were optimized. Chelation effect of CR by trivalent metal ions was in this order: Al(III)+Fe(III)>Fe(III)>Al(III). The chelation mechanism suggested that CR molecules gradually changed from hydrazones to electronegative azo with the increase of pH to 6-7, and electrostatic attraction between the Al3(OH)45+ or Fe(OH)2+ with the CR was favorable for the chelation reaction, in which the metal ions chelated with N atoms on naphthalene ring and amino groups of CR. Over 99% CR was removed under the optimal chelation and flotation conditions: chelation by composite Al(III)/Fe(III) with a concentration of 25 mg/L at pH of 7 for 25min; followed by flotation with SDS concentration of 20 mg/L and air flow rate of 50 mL/min for 20min. Under this condition, the COD and chromaticity removal efficiency were over 96% and 98%, respectively, and the turbidity was lower than 0.1 NTU, meeting the water discharge requirement. Eventually, resourceful utilization of flotation sludge via calcination was conducted to prepare Al-Fe spinel refractory material.

Abstract
The feasibility of foam separation for color removal from direct dyes-containing wastewater was assessed using actual textile wastewater as the research system and cetyl trimethyl ammonium bromide (CTAB) as the collector. The influences of liquid loading volume, air flow rate, surfactant concentration, and initial pH on the removal efficiency and reuse of CTAB in the foamate were studied. The results indicated that using CTAB as a collector for foam separation can provide good foaming quality and effectively remove color from textile wastewater. Under optimum operational conditions (liquid loading volume 450 mL, gas flow rate of 500 mL/min, CTAB concentration 20 mg/L, and an initial pH of 7.0), the removal efficiency reached 88.9%. The residual dye content met the discharge standard for the dyeing and finishing textile industry (GB4287-92) published by the Ministry of Environmental Protection of the People's Republic of China. Using recycled foamate in untreated wastewater, the removal efficiency of 87.5% was obtained with CTAB concentration 10 mg/L of the wastewater.
