In the tide of environmental protection and sustainable development, sludge treatment, as an important link of sewage treatment, is facing higher and higher requirements. The efficient dewatering of sludge is not only the key to reduce the volume of sludge, reduce the cost of transportation and storage, but also the premise of realizing the utilization of sludge resources. As a kind of chemical agent specially used to improve the dewatering performance of sludge, sludge enhancer is gradually becoming a star product in the field of sludge treatment.

A basic overview of sludge synergists

Sludge enhancer is a chemical agent that improves sludge dewatering efficiency by changing the surface structure and properties of sludge. It is usually composed of a variety of ingredients, including inorganic compounds, sludge surface structure modifier, degreaser, wall breaking agent, sludge surface treatment agent and sludge stripping agent. The synergistic effect of these components can effectively destroy the colloidal structure in the sludge, reduce the viscosity of the sludge, and increase the solid content of the sludge, so as to achieve efficient dehydration.

Two, the principle of action of sludge synergist

Damage the colloidal structure of the sludge: the colloidal structure of the sludge makes the sludge particles have a strong binding force and are difficult to separate. The wall breaking agent and the sludge surface structure modifier in the sludge synergist can destroy the colloidal structure, weaken the binding force between the sludge particles, and facilitate dehydration.

Reduce sludge viscosity: sludge viscosity is one of the important factors affecting the efficiency of dehydration. The degreaser and the sludge surface treatment agent in the sludge synergizer can reduce the viscosity of the sludge, make the sludge flow easier in the dewatering process, and reduce the resistance of the dewatering equipment.

Increase sludge solid content: By promoting the accumulation of solid particles in the sludge, the sludge synergist can increase the solid content of the sludge and reduce the water content. This not only reduces the volume of the sludge, but also facilitates subsequent transportation, storage and disposal.

Three. Application advantages of sludge synergists

Efficient dehydration: After the use of sludge synergists, the dehydration efficiency of sludge can be significantly improved. Combined with dewatering equipment such as filter press and centrifuge, the sludge moisture content can be reduced from more than 90% to 40%-60%, or even lower.

Reduce the cost: Because the sludge synergist can improve the dehydration efficiency, reduce the running time and energy consumption of the dehydration equipment, the treatment cost can be reduced. At the same time, the volume of dehydrated sludge is reduced, which also reduces the cost of transportation and storage.

Environmental protection and safety: Many sludge enhancers are made of environmentally friendly and non-toxic raw materials, which are harmless to the environment and human body. In the sludge treatment process, they will not cause damage to the useful components of the sludge, which is conducive to the resource utilization of the sludge.

Strong adaptability: sludge synergist is widely used in sludge dewatering treatment of various industries, including domestic sewage, industrial wastewater, etc. Whether it is municipal sludge treatment or industrial wastewater treatment, sludge synergists can play an important role.

Four, the selection and use of sludge synergists

In the selection of sludge synergists, it is necessary to consider the nature of the sludge, the performance of the treatment equipment and treatment requirements. Here are some suggestions for use:

Understand sludge properties: different sources of sludge have different properties, such as composition, moisture content, viscosity, etc. In the selection of sludge synergists, it is necessary to fully understand the nature of the sludge in order to select the appropriate agent.

Control dosage: The dosage of sludge enhancer should be adjusted according to the nature of the sludge and the performance of the treatment equipment. Too much or too little dosage may affect the treatment effect and economy. Therefore, it is recommended to conduct a small or pilot test to determine the best dosage.

Optimize the operating conditions: While using the sludge synergist, the operating conditions of the dewatering equipment should also be optimized, such as pressure, filtration speed, filter cloth cleaning, etc. The optimization of these conditions can improve the dehydration effect and reduce the treatment cost.

Regular monitoring effect: In the process of use, the dewatering effect and water content of the sludge should be regularly monitored to ensure the effectiveness of the sludge synergist. If the effect is not satisfactory, the dosage or operating conditions should be adjusted in time.

Market prospects of sludge synergists

With the increasingly strict environmental protection policies and the continuous progress of sludge treatment technology, the application prospect of sludge synergists in the field of sludge treatment is more and more broad. In the future, with the continuous innovation of technology and the continuous promotion of application, sludge synergists will play a more important role in the field of sludge treatment. At the same time, with the increasing market demand for environmental protection products, the market demand for sludge synergists will also continue to grow.

Six, Conclusion

Sludge enhancer, as an efficient and environmentally friendly sludge treatment agent, plays an important role in sludge dewatering treatment. Through the rational use of sludge enhancer, the dehydration efficiency of sludge can be significantly improved, the moisture content can be reduced, the equipment wear and blockage can be reduced, and the treatment cost can be reduced. At the same time, it also helps to promote the resource utilization of sludge and the development of environmental protection. In the future, with the continuous progress of technology and the continuous promotion of application, sludge synergists will usher in a better development prospect in the field of sludge treatment.
