Wastewater resource application is the future development direction of sewer therapy and is also an inevitable necessity for sustainable human development. Organic matter extracted from sewage or sludge, such as minerals and phospholipids, can be utilized as printing and coloring resources, main adsorbents, and biological flocculants. It is made use of in water treatment, agriculture, horticulture, the paper market, treatment, the building sector, and other fields and has fantastic relevance. Recycling worth.


(surfactant)

There are lots of types of bacteria in the continuing to be sludge. Consequently, the substances removed from it has to be a mix of various polymer compounds. Whether they are intracellular or extracellular polymer substances, they all have typical energetic teams, such as carboxyl, hydroxyl, and phosphate. Teams and other useful teams. The existence of these groups enables the extracted polymer materials to be made use of as heavy steel ion adsorbents.

As a tidy therapy technology, ultrasonic waves do not require the addition of chemicals during the activity and will certainly not create secondary air pollution. Ultrasonic waves can spread flocs in the water phase, and the cavitation effect can damage big bits into little bits. Ultrasound is an energy-intensive treatment approach, and its largest drawback is its high power usage, which limits the possibility of practical applications. Surfactant has a solubilizing result, which can clean off proteins on the cell membrane, increase the leaks in the structure of the cell membrane by influencing the osmotic stress, and escalate the damages to the sludge floc. In addition, surfactant activity can promote the removal of EPS from remaining sludge, transform the cell structure, and influence sludge residential or commercial properties.

Surfactant-enhanced ultrasonic approaches can be utilized to draw out natural polymer materials and as a pretreatment method to minimize power usage. The increase in the removal amount of PSs from the remaining sludge under the activity of surfactant-enhanced ultrasound results from the release of organic matter as a result of floc fragmentation and cell dissolution.

First, surfactants, such as anionic (such as sodium dodecyl sulfate, SDS) and cationic (such as cetyltrimethylammonium bromide, CTAB), are utilized to boost the connection in between sludge and polymer compounds. Communications in between. They can reduce the surface stress of sludge, making it much easier for polymer compounds to divide from sludge.

Subsequently, ultrasound is introduced to improve the extraction effect further. The solid resonance and shock waves produced by ultrasonic waves can destroy the structure of sludge and tear cell wall surfaces, consequently releasing more polymer materials. Furthermore, ultrasound can additionally promote the communication in between surfactants and polymer materials, making the removal process more effective.

Throughout the removal process, it is likewise needed to enhance the experimental criteria, such as the frequency, power, and activity time of ultrasonic waves, to attain the best removal effect.


(surfactant)

As a whole, surfactant-enhanced ultrasonic removal of polymer materials in residual sludge is an effective and ingenious method. It not just boosts removal efficiency yet also aids expand the range of source use of staying sludge, giving brand-new possibilities for the advancement of sewer therapy and source recovery areas. However, the functional application of this technique requires additional research study and optimization to solve possible technological difficulties and economic issues.
