To solve the problem of non-forming mud press of plate and frame filter press, you can start from the following aspects:
1. Optimization of sludge conditioning
Select the right sludge conditioner:
According to the specific properties of the sludge, select the appropriate sludge conditioner, such as polyacrylamide (PAM), inorganic coagulant, etc., to improve the dewatering performance of the sludge.
Adjust the amount of sludge conditioner:
Determine the optimal amount of sludge conditioner through tests to avoid excessive or insufficient sludge dewatering effect is not good.
Improve the flocculation effect of sludge:
Optimize the flocculation process of the sludge to ensure that the formed flocs are large, compact and easy to press and filter.
2. Check and maintain the equipment
Check filter cloth:
Check the integrity of the filter cloth regularly, if there is damage or blockage should be replaced or cleaned in time.
Check filter plate:
Check whether the filter plate is damaged or not tightly sealed, if there is a problem, it should be repaired or replaced in time.
Adjust the compression force:
According to the nature of the sludge and the design requirements of the filter press, adjust the appropriate pressing force to ensure that the filter cake can be tightly formed during the filtration process.
Three, standard operation process
Ensure adequate supply and appropriate concentration:
Before filtration, ensure that the sludge supply is sufficient and the concentration is appropriate to avoid too thin or too thick affecting the filtration effect.
Follow the operating procedures:
Filter press operation in strict accordance with the operating procedures to avoid improper operations such as unloading plate in advance and insufficient pressure.
Monitor the filtration process:
In the filtration process, closely monitor the operating state of the filter press and the forming of the filter cake, and adjust the operating parameters in time.
4. Optimize the process flow
Enhanced wastewater pretreatment:
Sufficient pretreatment of sewage, removal of suspended solids, grease and other impurities, improve the dewatering performance of sludge.
Adjust process flow:
According to the nature of the sludge and the characteristics of the filter press, optimize the process flow and improve the dewatering efficiency of the sludge.
Other measures
Increase filter time:
Under the premise of ensuring the safety of the equipment, the filter press time should be extended appropriately to improve the water content and forming effect of the filter cake.
Adjust the pressure of filter press:
According to the characteristics of the sludge and the design parameters of the filter press, adjust the pressure of the filter press to achieve the best filter effect.
Regular cleaning and maintenance:
Regular cleaning and maintenance of the filter press to maintain the cleanliness and integrity of the equipment to ensure the filtering effect.
In summary, to solve the problem of non-forming mud press of plate and frame filter press, it is necessary to start from many aspects such as sludge conditioning, equipment maintenance, operating process, process flow and other measures. Through comprehensive consideration and optimization of these factors, the filter press effect and sludge dewatering performance can be significantly improved.
