The use of hydrogen peroxide as an oxidation and iron (III) sulfate as a coagulant in the processing of tapioca flour liquid waste through the electrocoagulation method

Introduction

The tapioca flour processing industry is one of the many industries that produce liquid waste with high biochemical oxygen demand (BOD) and total suspended solid (TSS) content. If this liquid waste is not managed properly and discharged directly into the body of the water, it can cause environmental damage and pollution. Therefore, it is essential to do waste treatment so that it can be processed to be safe for the environment and water agencies.

The electrocoagulation method is a promising technology for treating liquid waste, including tapioca flour liquid waste. This method involves the use of an electric current to generate coagulant species that can remove contaminants from the waste. However, the efficiency of the electrocoagulation method can be improved by adding oxidizing agents and coagulants to the process.

This study aims to determine the effect of electrocoagulation time on the percentage of decreased COD and TSS concentrations in tapioca flour liquid waste with electrocoagulation methods added with hydrogen peroxide as oxidizing agents and iron (III) sulfate as coagulants. In addition, this study also wants to determine the optimum dose of hydrogen peroxide added in tapioca flour waste treatment.

Materials and Methods

The experiments were conducted in a laboratory with a batch scale. Iron electrodes were used with voltage variations of 6, 12, and 18 V. Hydrogen peroxide was added to waste with a variation of a dose of 0.7; 1.4; and 2.1 mg/l. Sampling was carried out after 30, 45, and 60 minutes since the electrode began to be electrified, then an analysis of the COD and TSS parameters was carried out.

Results

The results showed that the best decrease in COD occurred at a voltage of 18 V and an electrocoagulation time of 45 minutes, which succeeded in reducing COD levels by 67.41%. Meanwhile, the best decline in TSS occurs at the same voltage with an electrocoagulation time of 60 minutes, which succeeded in reducing TSS levels by 90.20%.

From the results of this study, it was also found that the optimum dose of hydrogen peroxide varies depending on the voltage used. At a voltage of 6 V, the optimum dose of hydrogen peroxide is 2.1 mg/l; at 12 V is 0.7 mg/l; And in 18 V is 1.4 mg/l with the same electrocoagulation time, which is 45 minutes. For the electrocoagulation time of 60 minutes, the voltage of 6 V and 18 V both show the optimum dose of hydrogen peroxide of 1.4 mg/l. However, at a voltage of 12 V, the optimum dose at 45 minutes remains 1.4 mg/l.

Discussion

The use of hydrogen peroxide as an oxidation agent in the electrocoagulation process can increase the efficiency of liquid waste treatment. Hydrogen peroxide functions to oxidize organic compounds contained in waste, thereby accelerating the process of reducing COD and TSS levels. In other words, hydrogen peroxide can help in elaborating harmful compounds into more easily deposited products.

Meanwhile, iron (iii) sulfate functions as a coagulant that plays a role in aggressing small particles dispersed in wastewater. In the coagulation process, these particles will join into larger particles (flok) and can be easily deposited. The combination of these two materials in the electrocoagulation process shows significant results in reducing waste concentrations.

The importance of this research not only lies in waste treatment but also contributes to environmental protection. By processing liquid waste from the tapioca flour processing industry, we can reduce water pollution that can negatively impact the ecosystem. In addition, this research also opens opportunities for the development of more efficient and environmentally friendly liquid waste treatment methods.

Conclusion

The use of hydrogen peroxide and iron (iii) sulfate as part of the electrocoagulation process in tapioca flour liquid waste processing shows a great potential in reducing the negative impact of waste on the environment, and can be applied in other processing industries that produce similar waste.

Recommendations

Based on the results of this study, it is recommended that the electrocoagulation method with hydrogen peroxide and iron (iii) sulfate be applied in other industries that produce liquid waste with high BOD and TSS content. In addition, further research is needed to optimize the parameters of the electrocoagulation process, such as voltage, electrocoagulation time, and dose of hydrogen peroxide, to improve the efficiency of the process.
