The press filter is a commonly used dewatering device, but it often faces the issue of sticky filter cakes during operation. This issue not only hampers dewatering efficiency but also complicates subsequent treatment processes. This article presents several strategies to mitigate the problem of sticky filter cakes in press filters for reference.
How to Solve the Sticky Filter Cake Issue in press filter?
Choose the Appropriate Filter Aid
Choose a suitable filter aid based on the characteristics of the sludge and specific dewatering requirements. It is essential to pay attention to both the dosage and application method of the filter aid, ensuring thorough mixing with the sludge.
Increase Sludge Solid Content
Increase the solid content of the sludge through processes such as concentration and sedimentation. Reducing the water content of the sludge helps shorten dewatering time and improve dewatering efficiency.
Choose the Right Filter Cloth Material and Regular Cleaning
Select the appropriate filter cloth material based on the properties of the sludge and dewatering requirements. For highly sticky sludge, choose filter cloths with high tensile strength and good abrasion resistance. Furthermore, regular cleaning of the filter cloth is crucial to prevent residual materials from clogging its pores.
Optimize Operating Parameters
Optimize the operating parameters of the plate and frame dewatering machine based on the properties of the sludge and dewatering requirements. For example, increase pressure, extend filtration time, etc., to improve dewatering performance.
Enhance Equipment Maintenance and Upkeep
Regularly maintain and service the press dewatering filter, checking that all components are in good condition and the machine is operating normally.
The problem of sticky filter cakes in plate and press filters is complex and requires a comprehensive approach for resolution. For more information, please visit the Bolian official website product page or contact us for professional consultation.
