Furthermore, surfactant activity can promote the extraction of EPS from staying sludge, transform the cell framework, and impact sludge properties.

Surfactant-enhanced ultrasonic techniques can be utilized to draw out natural polymer products and as a pretreatment approach to decrease energy usage. The increase in the extraction quantity of PSs from the continuing to be sludge under the activity of surfactant-enhanced ultrasound is because of the launch of raw material due to floc disintegration and cell dissolution.


(surfactant)

First, surfactants, such as anionic (such as salt dodecyl sulfate, SDS) and cationic (such as cetyltrimethylammonium bromide, CTAB), are made use of to enhance the partnership between sludge and polymer compounds. Interactions in between. They can reduce the surface area tension of sludge, making it less complicated for polymer materials to divide from sludge.

Subsequently, ultrasound is presented to boost the removal effect further. The solid resonance and shock waves produced by ultrasonic waves can destroy the framework of sludge and tear cell walls, thereby releasing more polymer substances. Additionally, ultrasound can likewise promote the communication between surfactants and polymer compounds, making the removal procedure more efficient.

During the extraction process, it is additionally essential to maximize the experimental specifications, such as the frequency, power, and action time of ultrasonic waves, to attain the most effective extraction effect.


(surfactant)

Generally, surfactant-enhanced ultrasonic removal of polymer substances in recurring sludge is an effective and ingenious technique. It not only improves removal performance yet likewise helps increase the extent of source use of remaining sludge, offering new opportunities for the development of sewage therapy and source healing fields.
