Water Evaporation in Filter Press Operation & Essential Cleaning Guide | Ranxu
Filter presses feature outstanding wastewater treatment capacity and can handle diverse types of wastewater steadily, though the feed pump endures heavy working load during feeding. The filter cloth efficiently traps contaminants to produce clear filtrate.
Water evaporation is inevitable under high operating temperatures and cuts down actual processing efficiency to some extent. Volume loss caused by evaporation is a normal occurrence in practical production. Monitoring ambient climate conditions during operation helps prolong equipment service life, an item frequently overlooked in daily production which requires extra attention.
Residual sludge and solid deposits accumulate inside the unit after long-term operation.
Continuous contact with filtrate plus high working pressure makes solid particles adhere tightly to filter cloth. Without timely cleaning, filter cloth clogging leads to lowered efficiency, shortened service life and even cloth burnout. Regular cleaning is therefore essential for sludge filter presses, with standard cleaning steps listed below:
Check filter cloth material characteristics before cleaning to adopt proper washing solutions:
Alkali-resistant filter cloth: soak in weak alkaline solution for 10–24 hours, fully rinse with clean water, air-dry to 90% dryness before reinstallation and operation.
Acid-resistant filter cloth: replace soaking solvent with mild acid solution instead.
