Tiaano Appraisal Test Kit used to confirm the possibility of Treatment. The sample's reduction on BOD & COD is pre test and confirming to proceed for lab test. [More]

The use of a Central Composite Design for the optimization. Arslen-Alton et al. concluded that the central composite design was used to optimize CI Acid Blue 193 treatment by electrocoagulation. The central composite design is capable of achieving maximum color, COD, TOC, by manipulating the COD, pH, electrical current density, and treatment time by means of a response surface quadratic model [9]. Cora and Hung were able to remove metallic ions between 90 and 99% after 30 minutes of treatment using an electrocoagulation/electrofiltration with a pH of 9.5 and cadmium chloride for the metallic ions [10].

Electrocoagulation-flotation is an alternative method to classic chemical coagulation for many reasons. ECF is capable of reducing the need for chemicals due to the fact that the electrodes provide the coagulant. However, many individuals still use chemical coagulants to attempt to enhance treatment. Traditionally, chemical coagulation involves the use of alum (aluminum sulfate), ferric chloride (FeCl3), or ferrous sulfate (Fe2SO4) which can be very expensive depending on the volume of water treated. When applying the coagulant, the coagulant performs a similar function as the electrodes, neutralizing the charge of the particulates, thereby allow them to agglomerate and settle at the bottom of the tank. In addition, electrocoagulation-flotation is capable of reducing waste production from wastewater treatment and also reduces the time necessary for treatment. [More]

Electrocoagulation-electroflotation (ECF) technology is a treatment process of applying electrical current to treat and flocculate contaminants without having to add coagulations. Shammas et al. stated that coagulation occurs with the current being applied, capable of removing small particles since direct current applied, setting them into motion. Also electrocoagulation could reduce residue for waste production [More]

The Electro coagulation model comprised with Ericohrome Black T and oil/water emulsion where the primary mechanism operated were aluminum hydroxide precipitate and charge neutralization of developed model for wastewater pollution considering hydrodynamic conditions using chemical reaction of reagents and pollutants, where a multivariable modeling of anodes was described. The model combined a macroscopic/maximum gradient approach for all processes with pseudo equilibrium. [More]

Isotherm kinetics for arsenic removal from aqueous solutions by means of electrocoagulation through response surface methodology. It concluded that COD and Colour removal of 81.6% and 98.4%, respectively, were capable of treating bio-digester effluent within an electrocoagulator. [More]

Electro Coagulation Reactor (ECR) consists of electrodes, which is arranged in anode & cathode. Using the principles of electrochemistry, the cathode is oxidized (loses electrons), while the water is reduced (gains electrons), thereby making the wastewater better treated. [More]

Waste Water Treatment Electro coagulation & Electro Oxidation design optimized Cl ions, temperature in degrees Celsius, pH, intensity of current, time of electrolysis. From the results, the authors observed that current intensity, COD (chemical oxygen demand), TOC (total organic carbon), and electrochemical oxidation were major parameters [More]

In the Electro coagulation-floatation apparatus, particulates would instead float to the top of the tank by means of formed hydrogen bubbles that are created from the anode. The floated particulates can be skimmed from the top of the tank. [More]

In the Coagulation Reactor, when the cathode electrode makes contact with the wastewater, the metal is emitted into the apparatus. Then the particulates are neutralized by the formation of hydroxide complexes for the purpose of forming agglomerates. These agglomerates begin to form at the bottom of the tank and can be siphen out through filtration. [More]
