The electrochemical treatment was an effective technique in dye processing and it can be enforced to remove color from dye solution. An Experimental setup was made for electrochemical treatment of synthetically prepared Reactive Black B dye in batch mode operation using aluminum electrodes. Based on probability the operating parameters such as pH, Concentration, Electrolysis time, Retention time were determined from which the color removal efficiency (CRE) is optimized. The maximum color removal efficiency of Reactive black B dye was achieved at 98.23% for the concentration of 10mg/l.

Removal of dye from wastewater has been investigated using the electrocoagulation method. Batch experiment has been conducted to remove the color from synthetically prepared acid red 87dye wastewater. Stainless steel and nickel foam sheets are used as cathode and anode, respectively. The effect of some operating parameters, such as current density, initial dye concentration and supporting electrolyte concentration, on color removal has been studied. It can be observed from the present investigations that the nickel foam electrode effectively removes color from the wastewater. Nickel hydroxyl species formed during the operation and also, nickel (II) hydroxide flocs formed in a subsequent stage, trap colloidal precipitates and make solid-liquid separation easier during the flotation stage. These stages of electrocoagulation must be optimized to design an economically feasible process.

Natural Mediator

The low molecular syringaldehyde was found to be a preferred natural mediator for pulp delignification in the electrochemically mediated delignification system (EMD-system). Electrochemical treatment of poplar kraft pulp with syringaldehyde results in the reduction of kappa number of about 28%, but the loss of viscosity is only 6.6%. During the process of electrochemically mediated delignification , the delignification efficiency is dependent on the voltage, the dosage of syringaldehyde , reaction temperature , pH value, reaction time and the composition of electrolyte solution. The optimum operating parameters of electrochemical delignification with syringaldehyde are obtained as follows: syringaldehyde 1mmol/l, voltage 1.8v, temperature 45°C, reaction time 4.5h, the pH-value in the range from 4.0 to 5.0, sodium sulfate 0.05mol/l.

External Power

Bio-electrochemical anaerobic digestion (AD) is one of the most recent advancement in anaerobic treatment processes. Microbial electrolysis cells (MECs) are used for bio-electrochemical treatment, where the supplied external power is used to enhance the performance of AD. Multiple studies have investigated the viability of MECs under various operating parameters and for different organic wastes. The present paper aims at reviewing the latest literature regarding bio-electrochemical enhanced AD through MECs. It was concluded that MEC reactors significantly enhance AD performance under different supplied voltages, temperatures, electrodes configuration, as well as other operating parameters. Based on the compiled literature, further comprehensive life cycle assessment of MECs is recommended prior to any full-scale implementation.

Removal Efficiencies

In this study, a novel treatment approach combining biological treatment, struvite crystallization, and electrochemical treatment was developed and its efficiency for the simultaneous removal of pollutants and recovery of nutrients from high strength swine wastewater (SWW) was verified. For all the parameters, maximum removal efficiencies in the lab-scale test were obtained in the range of 93.0–98.7% except for total solids (TS) (79.4%). Farm-scale process showed overall removal efficiencies for total nitrogen (TN), total phosphorus (TP), soluble total organic carbon (sTOC), and color as 94.5%, 67.0%, 96.1%, and 98.9%, respectively, while TS, suspended solids (SS), ammonium nitrogen (NH4-N), and ortho-phosphate (O-P) concentrations were reduced by 91.5%, 99.6%, 98.6%, and 91.9%, respectively. Moreover, the struvite recovered from SWW showed heavy metal concentrations within the range of the Korean standard for fertilizers and feedstocks and thus, suggesting its potential application as fertilizer and in animal feed production. Using the proposed process, the SWW was converted to liquid compost as a quick-acting fertilizer, struvite as a slow-release fertilizer, and the decolorized and disinfected effluent after electrochemical treatment was safe for discharge according to Korean standard. Therefore, the novel integrated treatment process used in this study can be considered as a solution for SWW management and for the simultaneous removal and recycling of nutrients (N and P).
