Sunflower Husk to Remove Oil from Wastewater
https://doi.org/10.18412/1816-0395-2023-10-48-53
Abstract
The proposal concerns the use of native and modified sunflower husks for wastewater treatment from oil. It was found that acid and alkali modified at different temperatures increase the sorption properties of sunflower husk, and an increase in temperature and concentration of the substance during modification of the husk contributes to a decrease in the concentration of residual oil in model wastewater solutions treated with modified sunflower husk. It was found that the greatest removal of oil from model solutions of wastewater occurs when sunflower husk modified with 10 % sulfuric acid are used for treatment at 121 °C and and 1 atm. pressure. It was concluded that sunflower husk modified with acids and alkalis increases the degree of purification of oil-contaminated wastewater.
