Removal of Oil and Grease From Wastewater Using Natural Adsorbents

Abstract

There are several pollutants that can harm our environment. Oil and grease are one of the examples of a pollutant that can cause a severe environmental problem. The highest concentration of oil and grease inside the sewer system can cause the sewer to clog that can lead to overflow. It can affect not only to the environment but can also affecting our health. There are various methods of oil and grease removal that one of the examples is by using adsorption method. This method commonly uses activated carbon that is one of the effective adsorbents. Although effective, the cost for activated carbon is expensive thus a study was conducted by using agricultural residues as alternative adsorbents for oil and grease removal. This study objective is to determine the ability of two adsorbents, which are sugarcane bagasse and banana pith as an adsorbent in removing oil and grease from wastewater. It involved the characterization of adsorbent and the performance studies of the adsorbent. The adsorbent was characterized in term of physical and chemical characterization. Dosage and contact time are the parameter used for performance studies, to see the ability of adsorbents in removing oil and grease.

Sustainable Materials Production for Oily Wastewater Treatment

“…Based on the study [3], [6], [7], [8], [9] and [10] A 500 ml three nick conical flask (Goel, Germany) was used as an adsorption chamber. The adsorption temperature was measured and recorded using a glass thermometer submerged within the flask.…”

“…One of the pollutants that can cause an environmental problem is the present of oil and grease inside water system [1] and [2]. When petroleum wastewater is introduced into the aquatic environment at high concentrations, it becomes toxic to aquatic organisms and damages other ecosystems in the body of water [3].Oily wastewater discharge into natural water streams has risen as a result of industrial growth and human activities. Crude oil spills, power plants, extraction of crude oil, stations, petrochemical plants, and domestic trash such as spent cooking oil and lubricant from vehicle spills are all sources of oily wastewater.…”

“…Another option is deemulsification, although it is not frequently utilized due to its low removal efficiency and expensive cost. [3]. Various research has been done in order to determine the best methods for removing oil from water.…”

“…One of the most popular ways for eliminating pollutants is adsorption, which is one of the methods described above. The advantages of employing adsorption techniques, according to earlier studies, include high oil removal efficiency, cheap cost, and low processing cost [3].…”

Studies on Adsorption Characteristics of Corn Cobs Activated Carbon for the Removal of Oil and Grease from Oil Refinery Desalter Effluent in a Downflow Fixed Bed Adsorption Equipment

“…Numerous agricultural wastes' ACs such as rice husks (Umembamalu et al, 2020), banana peels (Borhan et al, 2014), carbonised grass (Rahmat et al, 2017), and sugarcanne bagasse (Nadzirah et al, 2015) have been harnessed for the reduction of O&G in effluents even commerically obtained granular and powdered ACs (Al-Kaabi et al, 2019;Fulazzaky and Omar, 2012;Grieves et al, 1980). Also, raw agricultural wastes such as sugarcane bagasse (Boni et al, 2016;Hamid et al, 2016) and banana pith (Hamid et al, 2016;Sasirekha et al, 2018), and plants such as neem, Posidonia oceanica (Jmaa and Kallel, 2019). and curry leaves (Sasirekha et al, 2018) have been used for O&G removal from effluents.…”
