For the problems of high moisture content of pharmaceutical sludge and shapeless mud, the following are some effective solutions:

First, the use of sludge conditioner

Sludge conditioner is a chemical agent that can change the surface structure of sludge, reduce the surface load of sludge solids, and destroy the structure of bacteria. By adding appropriate amount of sludge conditioner, the dewatering performance of sludge can be effectively improved, and the sludge particles can be agglomerated and settled, so as to improve the dewatering efficiency. At the same time, the sludge conditioner can also reduce the viscosity of the sludge, increase its compressibility, and make the mud pressing process more smooth.

Two, increase the press pressure and press time

For the process of dewatering sludge using equipment such as plate and frame filter press, the press effect of sludge can be improved by increasing the pressure and press time of the filter press. Increasing the pressure forces more water to be separated from the sludge, while extending the pressing time further reduces the moisture content of the sludge. However, it should be noted that too high pressure and too long pressing time may cause damage to the equipment, so it is necessary to operate within the scope of the equipment.

Three. Optimization of sludge treatment process

Combined with the production process and wastewater treatment process of the pharmaceutical industry, the optimization of the sludge treatment process is also an effective way to solve the problem of high water content and unformed mud. For example, the amount of sludge produced can be reduced by adjusting the wastewater treatment process; Or in the sludge treatment process to increase the pre-treatment link, such as the use of coagulation precipitation, air flotation and other methods to improve the dewatering performance of the sludge.

Four, replace or upgrade equipment

If the above methods do not solve the problem, you may need to consider replacing or upgrading the existing sludge dewatering equipment. For example, it can be replaced with a plate and frame filter press with higher press capacity, or more advanced sludge dewatering technology can be used, such as centrifugal dehydrator, belt filter press, etc. These devices generally have higher dehydration efficiency and better adaptability to meet the needs of different sludge treatment scenarios.

Five, comprehensive solutions

For the problems of high moisture content of pharmaceutical sludge and shapidity of pressed mud, it is usually necessary to issue a comprehensive solution combining a variety of methods. Through the process of pilot test, pilot adjustment and on-machine calibration, the parameters are strictly controlled to ensure that the treatment effect reaches the ideal state. At the same time, it is also necessary to flexibly adjust the treatment scheme according to the nature of the sludge and the scale of treatment, in order to achieve the best dehydration effect and economic benefits.

In summary, to solve the problem of high moisture content of pharmaceutical sludge and shapeless mud pressing, it is necessary to start from many aspects, including the use of sludge conditioner, increasing the pressure and pressing time of the filter press, optimizing the sludge treatment process, replacing or upgrading the equipment, and issuing comprehensive solutions. Through scientific and reasonable treatment methods and advanced technical means, it can effectively reduce the moisture content of sludge, improve the efficiency and quality of mud pressing, and contribute to the sustainable development of the pharmaceutical industry.
