Abstract
The wastewater filtration system and method relates to systems and methods that use Ruba Al-Khali Saudi sand as the filtration media in systems for treating industrial wastewater. Ruba Al-Khali Saudi sand is effective in removing organic dyes, particularly rhodamine B, from the wastewater. The method includes bringing wastewater having an organic dye constituent into contact with the Saudi sand for a period of time sufficient to adsorb the organic dye. The system may include a batch reactor, such as a fixed bed or moving bed reactor, or a continuous flow reactor, such as a column reactor. When a batch reactor is used, the method may benefit from shaking or agitating the filtration media, particularly in the dark or under low ambient light conditions. The method may include regenerating the Saudi sand after use by heating the filtration media.
