Treatment of Rubber Industry Wastewater by Using Fenton Reagent and Activated Carbon

Abstract

Rubber industries are sufficiently developed and widely spread countryside as well as in some big cities in Indonesia. An Increasing number of rubber industries have also increased rubber wastewater. However, the rubber industry development should pay attention to the impact on the environment. The rubber wastewater is problematic, because of high Chemical Oxygen Demand (COD) content. So far, the methods that have been used to remove COD in the waste water have been proven to be costly and time consuming. The research objective is to treat the rubber wastewater by using a combination of Fenton reagent and activated carbon adsorption. In this study, effect of molar ratios of Fenton reagent, pH, and reaction time on COD degradation were studied. After treating with Fenton reagent, the wastewater was passed into an adsorption column of 20 cm height of activated carbon granules. The maximum COD degradation of 95% were found by using a combination of Fenton reagent and activated carbon, with a molar ratio of reagent Fenton 1:250 and a reaction time of 45 minutes. The final COD of 71 mg/l, TSS of 70 mg/l, and pH of 7.8 were found which fulfilled the environmental quality standard regulation for industrial wastewater in Indonesia.

Enhanced Pretreatment of Natural Rubber Industrial Wastewater Using Magnetic Seed Coagulation with Ca(OH)2

“…Rubber is the third largest merchandise export item of Sri Lanka, producing 70,867-78,204 Mt of rubber per year (2019-2022 data) [3,4]. Rubber manufacturing facilities have been driven to enhance their production capabilities due to the rising demand for natural rubber, and this has led to a simultaneous increase in water demand for the manufacturing factories, which in turn has meant that large amounts of rubber effluent are now being discharged into natural water streams [5] as wastewater (WW), which is one of the most severe pollutants from the rubber industry. Generally, natural rubber industrial wastewater (NRIWW) comprises a small portion of uncoagulated latex and serum liquid and high amounts of proteins, lipids, carotenoids, carbohydrates, sugar, and organic and inorganic salts, which generate high COD and BOD in the wastewater and specifically low pH values.…”

Testing of a Laboratory Wastewater Treatment Prototype Using Coagulation, Adsorption and Photo-Fenton Processes

“…The Fenton process can be carried out at room temperature and atmospheric pressure conditions. Fenton is one of the most effective advanced methods in the degradation process of many types of pollutants in wastewater (Agustina et al, 2016;Agustina et al, 2017). Fenton is related to reactions such as hydrogen peroxide with iron ions.…”

Rubber Industry Wastewater Treatment Using A Combination Of Ozonation And Modified PES-Nano ZnO Membranes

“…Then, the Advanced Oxidation Process (AOP) method shows great potential in various fields of wastewater treatment applications. The technique reduces organic contaminants, destroys specific pollutants, and reduces color and odor [7]. Ozonation, as one of the AOPs technologies, can break down non-biological natural substances that have large molecular weights into smaller organic materials.…”
