“…Leachate contains organic compounds (hydrocarbons, humic acids, sulfates, tanates, and gallates) and inorganic (sodium, potassium, calcium, magnesium, chlorine, sulfate, phosphate, phenol, nitrogen and heavy metal compounds) which is highly polluting the soil environment. Concentrations of these components in leachate can reach 1000 to 5000 times higher than concentrations in groundwater [5]- [8].…”

Leachate is water which is formed in a pile of garbage that dissolves a lot of existing compounds so that it has a very high pollutant content, especially organics substances. Leachate has the potential to cause water pollution, both surface water, ground water and underground water, so it needs to be managed properly. Leachate processing uses a combination of electrocoagulation and aeration methods. The objective of this study is to determine leachate characteristics before and after the processes, the optimum treatment conditions, and the effectiveness of the treatment processes in reducing pollutant content. Electrocoagulation is able to reduce the characteristics of the waste pollutant content in terms of increasing pH and decreasing total disolved solid (TDS), total suspended solid (TSS), chemical oxygen demand (COD), biological oxygen demand (BOD5), and waste turbidity. This condition occurs due to the process of coagulation of pollutants by applying electric current to electrochemical reactions. The working principle of electrocoagulation is the dissolution of anode metal (M+), which reacts with hydroxyl ions (OH-) to form coagulants. The experiment was conducted in batch, where the leachate is put into an electrochemical cell containing 2 aluminum electrodes with dimensions of 10 cm x 10 cm. The parameters varied are the aeration process and variations in the addition of NaCl. The optimum conditions are achieved in the electrocoagulation process with aeration and the addition of 2 g/L NaCl. The most significant processing effectiveness of the process is TDS 34.06%, TSS 81.46%, COD 54.26%, BOD5 53.76%, and turbidity 92.92% respectively.

“…Energy is inextricably linked to human life. Until now, difficulties in the energy sector have remained a severe concern in a number of nations, particularly in Indonesia, due to the country's continued reliance on fossil energy, specifically 96% (48% petroleum, 18% gas, and 30% coal) [1], [2]. The depletion in fossil energy reserves is inversely related to the high usage of fossil energy.…”

Utilizing an Oxyhydrogen Reactor to Produce Hydrogen Gas as a New Source of Energy from Textile Effluent

Textile wastewater can disrupt the environmental equilibrium. One type of textile waste processing is the production of hydrogen gas as a new and sustainable energy source. The water electrolysis method may be used to convert textile waste into hydrogen gas. In this study, hydrogen gas was produced from textile waste in two stages: electroplating waste treatment with an electrocoagulator and then processing textile waste into hydrogen gas using an oxyhydrogen reactor. Various catalysts, including NaOH, KOH, NaCl, and NaHCO3, were used in the process of converting textile waste into hydrogen gas, with a concentration of 0.5 M and an electrolysis period of 5 minutes. The addition of a catalyst is intended to identify the optimal concentration in the conversion of textile waste to hydrogen gas. The optimal KOH catalyst concentration for obtaining hydrogen gas was determined through study and analysis.

Tofu waste liquid contains high levels of organic impurities, such as protein and amino acids. These organic compounds cause the tofu industrial wastewater to contain high biological oxygen demand (BOD), chemical oxygen demand (COD), pH and total suspended solid (TSS) which can pollute the environment. In general, the liquid waste from the tofu factory is discharged directly into rivers through sewers and rivers. Most of the tofu wastewater contains various kinds of pollutants which may be produced in the form of organic pollutants (foul smelling), inorganic pollutants (spicy and colored), so they are dangerous to the surrounding environment and need to be treated. One alternative to tofu liquid waste treatment is electrocoagulation. The electrocoagulation method has the potential to purify tofu wastewater and reduce the content of BOD, COD, TSS and neutralize pH without the addition of certain chemical coagulants. The purpose of this study was to obtain the characteristics and levels of pollutants contained in tofu industrial wastewater before and after processing, and to determine the effectiveness of the electrocoagulation method with various variations in voltage and reaction time. The electrocoagulation tub is attached with a cable connected to the power supply, then connected to a current source with a variable voltage (8; 10; 12 V) and a variable reaction time (30; 60; 90; 120; 150 minutes). The optimum conditions were obtained at a voltage variation of 12 volts and a reaction time of 150 minutes, with a percentage increase in pH of 72.33% to 5.98, a decrease in COD of 28.57% to 10 mg/L, a decrease in BOD5 of 46.87% to 2, 29 mg/L, and TSS from 11.47% to 21.6 mg/L.
