The application of sludge enhancer in the sludge conditioning of pharmaceutical plants has indeed shown the characteristics of simplicity and remarkable effect. The following is a detailed elaboration of this view:
One. Mechanism of action of sludge synergists
Sludge enhancer is a chemical agent specially used to improve the dewatering performance of sludge. It can significantly improve the dewatering performance of sludge by destroying the colloidal structure in sludge, reducing the viscosity of sludge and increasing the solid content of sludge. Specifically, the sludge synergist can change the surface properties of the sludge particles, such as charge distribution and hydrophobicity, making it easier to aggregate and precipitate between the sludge particles, thereby reducing the free water content in the sludge. At the same time, it can also destroy the microbial cell structure in the sludge, releasing bound water inside the cells, which is often difficult to remove during conventional dehydration.
Advantages of sludge synergists in sludge conditioning of pharmaceutical plants
Effective:
Reduce water content: Sludge enhancers can significantly reduce the water content of the sludge, making it easier to handle and dispose of. For example, combined with the plate and frame filter press, the moisture content of the sludge can be reduced from more than 90% to 35%~50%, to achieve the purpose of deep dehydration.
Improve dewatering efficiency: sludge synergists can significantly improve the dewatering efficiency of sludge and shorten the dewatering time, thus reducing the running time and energy consumption of dewatering equipment.
Easy to use:
Simple operation: The use of sludge enhancer is relatively simple, just add it evenly to the sludge, and after full mixing reaction, it can be dehydrated.
Strong adaptability: sludge synergists have good adaptability to different types of sludge, and can be selected and adjusted according to the specific properties and treatment requirements of the sludge.
Three. Practical Application Cases
Taking a pharmaceutical factory in Guangdong as an example, the sludge treatment of the factory is difficult, the mud pressing effect is poor, the moisture content is high, and the mud pressing time is as long as 12 hours. Through the introduction of sludge enhancer for sludge conditioning, the sludge moisture content is finally achieved as low as 52%, which greatly improves the efficiency and effect of sludge treatment.
Four, use precautions
Although sludge synergists show significant advantages in sludge conditioning in pharmaceutical plants, the following points still need to be noted during use:
Select the right sludge enhancer: Select the right sludge enhancer according to the nature of the sludge and treatment requirements.
Control dosage: The dosage of sludge enhancer should be adjusted according to the nature of the sludge and the performance of the treatment equipment, so as to avoid too much or too little influence on the treatment effect and economy.
Monitoring treatment 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.
Pay attention to environmental protection requirements: when selecting and using sludge enhancers, relevant environmental regulations and standards should be complied with to ensure that the treated sludge meets environmental protection requirements.
In summary, the application of sludge enhancer in the sludge conditioning of pharmaceutical plants is simple and effective, which can significantly reduce the moisture content of sludge and improve the dehydration efficiency, and provide strong support for the sludge treatment of pharmaceutical plants.
