Frequently Asked Question
1. How Do I Know When the Filter Press Is Full?
The diaphragm pump will get to 30 second to one minute intervals between thrusts, indicating that pressure has increased due to solids building up inside the press cavities. This is your signal that the press is full.
2. What Is Involved in Routine Filter Press Maintenance?
Cloth cleaning, dumping, check hoses and connections.
3. How Often Should I Change the Hydraulic Filter?
Whenever you change your oil, you should change your filter.
4. When Do the Cloths Need to Be Cleaned or Replaced?
The filter cake will begin to become wet, slimy and not as dry. This is your indicator that the cloths need to be cleaned. (see number 5 for cleaning info). If you have already cleaned your cloths and your process has not changed but you are still getting slimy filter cake, it may be time to replace your cloths. Cloth life varies from installation to installation and depends on such variables as frequency of cycles, proper cleaning and maintenance and the type of sludge that is generated. Generally speaking for most installations cloths can last up to 6 months at the most.
5. Will I Need to Replace the Plates?
Plates generally last years unless they become cracked, broken or warped. It is good practice to examine the plates during press cleaning and dumping.
6. What Are the Factors That Affect Filter Press Filtration?
- Feed slurry solids percentage
- Slurry particle size distribution
- Chamber thickness
- Solid material permeability
7. Can I Add More Plates to My Current Press?
You may be able to add a couple of plates without expanding your sidebars if your press is not already expandable but care must be taken to ensure that you have adequate cleaning room when dumping the press and cleaning the cloths.
8. How Long Is the Cycle Time?
Cycle time is dependent on solids loading and can take anywhere from 2-4 hours on average. (Closer to four hours for typical metal hydroxide waste.)
9. What Can I Do to Ensure the Driest Possible Filter Cake?
Be sure cloths are cleaned as needed and the air blow-down system is run for a full cycle. You may also wish to add a sludge dryer to your system. A dryer accepts filter press cake and dries it further to provide up to a 4:1 sludge reduction.
10. Why Are There Solids in My Filtrate?
There are several possible causes. You might not have the proper cloths for you application or if you have been using the same cloths for an extended amount of time, you may have holes in the filter cloths. The gasketed cloth may have slipped out of the grooves. Or, perhaps, the cloth on the head plate may not be properly secured.
