Electrocoagulation of Textile Effluent: RSM and ANN Modeling

The capability of response surface methodology (RSM), artificial neural network (ANN), and adaptive neuro-fuzzy inference systems (ANFIS) in modeling and predicting moisture content reduction in the drying of cocoyam (Colocasia taro) slices was the purpose of this study. Design of experiment was utilized. Modified Fick's second law of diffusion was used to determine effective moisture diffusivity (D eff ). Results indicated that drying time, air velocity, and temperature significantly affected the drying process. D e ff values obtained ranged from 2.97 × 10 −10 to 7.30 × 10 −10 m/s. Page model with R 2 = 0.994, SSE = 0.0053, RMSE = 0.0611, best described the kinetics of the drying process. ANN, RSM, and ANFIS all showed significant modeling and predicting ability with R 2 of 0.9583, 0.9519, and 0.9971, respectively. Genetic algorithm (GA) optimization showed minimum moisture content of 14.362%, 11.919%, and 11.293% for RSM-GA, ANN-GA, and ANFIS-GA, respectively. Additional statistical analysis lent credence to ANFIS as the best in modeling and predicting the moisture content reduction of cocoyam slices.

“…The relationship between the response ( y ) and the independent variables were expressed in Equation 6 (Murugan et al., 2009):

y = f (x_{1}, x_{2}, x_{3} \dots . x_{k}) + ε,

where x 1 , x 2 , x 3 , …, x k are the independent variables, ε is the error term, while k refers to the number of independent variables.…”

“…Since then, various carbon‐coating methods have been published by using different carbon sources, most of which are based on the decomposition of organic precursors, such as sugars,2 polymers,3 or glycols4 in inert or reducing atmosphere. When such carbon‐coating methods are applied to classical cathodic materials, such as highly oxidized transition metal oxides, they often reduce the compound even to the elemental metal.…”

Chemical lithiation and carbon coating of cathode materials can lead to strongly improved electrochemical properties, especially if the active materials have low electronic conductivity. This behavior is quite often the case for new high-capacity materials. A novel synthesis method is presented in which the two processes are performed simultaneously by employing Li2C2 as both the carbon and the lithium source. In this contact reaction, the acetylide anion C2(2-) is oxidized to carbon and deposited directly on the surface of the active material, while lithium is reductively inserted into the oxidant. Two different synthesis routes are demonstrated: a tribochemical approach at room temperature and heat treatments between 150 and 600 °C. The applicability of these new carbon-coating methods are demonstrated on various crystalline and amorphous Li(x)V2O5 phases. The composites obtained were characterized by powder X-ray diffraction, transmission electron microscopy, and Raman spectroscopy. In addition, electrochemical data confirm the chemical lithiation and show that lithiated Li(x)V2O5 with specific phases can be prepared selectively.

“…Appendix Table 5 provides a summary table considering the parameters and the dye(s) treated. Upon further assessments, it is observed that only two authors considered varying dyes (albeit they are from the same classification) (Körbahti 2007;Murugan et al 2009), while only one employed combined electrocoagulation/chemical coagulation using only one coagulant (powdered activated carbon) (Taheri et al 2013). An investigation of several textile dyes is important because the physical and chemical nature of conventional textile dye wastewater can be very complex.…”

This study assessed the efficiency of electrocoagulation (ECF) coupled with an addition of chemical coagulant to decolorize textile dye. Tests were conducted using Box Behnken methodology to vary six parameters: dye type, weight, coagulant type, dose, initial pH and current density. The combination of electrocoagulation and chemical coagulation was able to decolorize dye up to 99.42 % in 30 min of treatment time which is remarkably shorter in comparison with using conventional chemical coagulation. High color removal was found to be contingent upon the dye type and current density, along with the interactions between the current density and the coagulant dose. The addition of chemical coagulants did enhanced treatment efficiency.
