Study on the treatment of photovoltaic wastewater using electrocoagulation: Fluoride removal with aluminium electrodes—Characteristics of products

Electrochemical treatment involving a coupled coagulation and floatation was performed in the removal of Doxycycline Hyclate (DCH) from aqueous solutions. All the experiments were carried out in an electrochemical reactor of 1.5 L which contained aluminium electrodes as cathode and anode. The removal of doxycycline hyclate (DCH) species by EC/EF was determined as a function of electrolysis time, pH, current intensity, flow rate and DCH concentration. From the observed results, it was corroborated that the DCH removal through the EC/EF process was excellent. The effective contribution from initial pH (7.03) and current intensity (5.39 mA cm -2 ) was very much remarkable and well apparent from flocs of good buoyancy. The removal of DCH was inversely proportional to spacing between electrodes (SBE) and circulating flow rate in the presence of the supporting NaCl electrolyte of 1 g L -1 . It was also highly promoted by the addition of NaCl in comparison to NaNO 3 and KCl to the electrolytic system. The compliance of four kinetic models was verified with DCH removal system. The free energy values from DKR model suggested the nature of bonding by chemical forces. Characterization by FTIR, SEM and XRD interpreted the assignments of various functional groups, surface morphology and crystalline incorporated amorphous nature, respectively of electro -generated flocs. The current efficiency and specific electrical energy consumption at optimized conditions of the EC/EF system were calculated.

“…It was reported that electrocoagulation process has been widely applied to treat wastewater such as cutting oil emulsion wastewater [4] and textile wastewater [5]. In addition, researchers claimed that electrocoagulation process also successfully removed heavy metals from wastewater such as mercury (III) [6], phosphate [7,8], arsenic [9], fluoride [10] and antimony [11]. Electrocoagulation has advantages of minimum chemical addition and low maintenance.…”

Abstract. Herbicide has been widely used since it was first marketed. Consumption of water contains glyphosate herbicide can bring adverse effects to human health. This study was intended to evaluate the performance of electrocoagulation process using copper electrodes for glyphosate removal in aqueous solution. Synthetic glyphosate powder has been diluted in deionized water. An electrocoagulation tank of 500 mL with two copper plates electrodes, same in dimensions were setup. The effects of continuous variables of initial glyphosate concentration, electrocoagulation time and current density, were discussed in detail. Production of copper cations showed an ability to neutralize negatively charged particles, then, encouraged to bind together to form aggregates of flocs composed of a combination of glyphosate and copper hydroxide. This study revealed that electrocoagulation process using copper electrodes is reliable by indicating 46.69% glyphosate removal. Finally, it can be concluded that electrocoagulation process using copper electrodes is efficient for glyphosate removal from aqueous environments.

“…The other aspect of electrocoagulation process is energy efficacy which calculated by ratio of quantity of water treatment and energy input. The energy input of electrocoagulation system can be received from AC utility via rectifier circuit, in addition DC renewable energy sources such photovoltaic system can be applied especially in the rural area which no electricity from utility [9,10],In this paper, the combination of benefit of electrocoagulation and photovoltaic for water purification is proposed. The water purification and water quality parameter and standard are studied.…”

This paper demonstrates technique of water purification using electro-coagulation method. This system is composed of DC electric source 200 V 30 A connect to the anode and cathode terminals. The DC power supply can be received from utility or solar energy. The sample of raw water from reservoir is used to conduct experimental reaction with electrocoagulation system in order to improve water quality. The water purification experimental was implemented by batch processing with varying electrolysis time. The parameter of electro-coagulation and water quality parameters are collected such as electric voltage, electric current, water temperature, pH, dissolved oxygen (DO), total dissolved solid (TDS) and electro-conductivity. The result found that the water quality has improved with the standard of domestic water supply and also drinking water standard.
