Backwash and operating cleaning
Verify clean-water quality, pressure or flow, valve timing and distribution against the equipment instructions.
Permeability maintenance for porous ceramic media
Ceramic Filter Plate Cleaning and Regeneration
Maintain ceramic filter permeability with backwashing, ultrasonic cleaning and controlled regeneration based on slurry deposits and operating conditions.
BackwashRoutine method
UltrasonicPeriodic option
Controlled instructionChemistry
Deposit + trendDecision input
Cleaning basisRoutine Periodic Regeneration
Identify the Deposit Before Increasing Cleaning Intensity
Loss of permeability can come from fine-particle penetration, mineral scale, process reagent film, incomplete backwash, blocked channels or physical plate damage.
Ultrasonic cleaning
Check equipment function, coverage and cycle condition using the controlled BOYUN procedure.
Chemical treatment when approved
Select chemistry only after deposit, plate and site compatibility review.
Chemical safety and accuracy
This page intentionally does not publish a universal chemical, concentration, temperature or duration. Use the current BOYUN instruction for the identified plate and deposit, the chemical supplier SDS and the site’s risk assessment, permit, PPE, ventilation, containment, neutralization and disposal requirements.
Condition evidence
Separate Fouling from Damage or Flow-Path Faults
Cleaning will not repair a cracked plate, failed connector, blocked internal passage or incorrect valve sequence.
Performance trendFiltrate flow, vacuum, cake, moisture and change over time.
Deposit evidenceColor, location, texture and laboratory identification where needed.
Plate conditionCracks, chips, sealing edge, connector and scraper contact.
Water qualitySuspended solids, hardness, ions and contamination relevant to scale.
Process chemistrypH, temperature, reagents and recent operating changes.

Escalate Cleaning Only with Evidence
Record the response after each approved step so the effective method is known.
Confirm trend
Verify measurement, feed and cycle baseline.
Inspect system
Check valve, backwash, channels and plate integrity.
Identify deposit
Use process history and analysis where needed.
Apply approved method
Follow the controlled operating and safety instruction.
Verify and record
Compare permeability and filtration performance.
Clean or replace
Know When Regeneration Is Not the Answer
Remove damaged or unsafe plates from service and investigate why the damage occurred.
| Observation | Likely decision | Required review |
|---|---|---|
| Performance recovers after routine backwash | Continue controlled routine cleaning. | Confirm frequency, water quality and trend. |
| Performance responds only to periodic cleaning | Optimize the approved periodic schedule. | Identify deposit source and avoid over-cleaning. |
| No response despite correct flow and method | Investigate internal blockage or incompatible deposit. | Technical review before stronger chemistry. |
| Crack, chip, seal damage or leakage | Remove/replace according to equipment procedure. | Check scraper clearance, handling and installation. |
| Repeated short life | Treat as a system problem. | Review feed, chemistry, cleaning, mechanics and plate selection. |
Safety before inspection or maintenance
Stop the equipment and isolate all hazardous energy that can cause rotation, vacuum, pressure, stored mechanical movement, electrical energization or chemical exposure. Follow the site lockout and permit procedure; inspection and maintenance must be performed only by authorized personnel.

Practical answers
Frequently Asked Questions
These answers support project preparation; the final recommendation depends on the actual duty.
Why is representative slurry data required?
Mineral names do not define filterability. Particle-size distribution, mineralogy, clay, reagents, solids and temperature can change cake formation, permeability and release. Use filterability testing when results matter commercially.
What should be sent for a preliminary review?
Provide dry-solids throughput, feed solids, particle-size data, target cake moisture, operating schedule, elevation and available utilities through the quote request.
Can BOYUN promise cake moisture from the mineral name alone?
No. A defensible target must be tied to representative feed data, test conditions, equipment scope and an agreed operating basis.
Define the Next Engineering Step
Share the feed, throughput, operating target and site constraints. BOYUN will identify missing information and recommend testing, sizing or the appropriate equipment scope.
