Connect Filtration to a Measured Water Balance
Disc filtration separates a filtrate stream while producing cake. The usable contribution depends on feed water, filtrate quality, losses, washing, downtime and the plant’s reuse requirements.
Match water to its reuse point
Check suspended solids and any chemistry that matters to grinding, flotation or utilities.
Provide storage and control
Define receivers, pumping, surge, overflow, return lines and upset handling.
Application boundary
Do not describe a universal recovery percentage. Report the calculation boundary, feed and cake water, wash water, filtrate, leakage or evaporation, availability and measured operating period.

Variables That Control the Filtration Result
Treat these inputs as measured ranges. A single nominal value does not describe seasonal, orebody or campaign variation.
Plant water balanceFresh water, recycle streams, inventories, losses and discharge.
Filter feedSlurry flow, dry solids, feed solids and variability.
Cake waterMeasured cake moisture and cake production under defined conditions.
Filtrate qualitySuspended solids and chemistry relevant to the proposed reuse.
Auxiliary waterCloth or plate wash, seal water and cleaning demand.
Upset handlingStart-up, shutdown, off-spec filtrate and storage capacity.

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.
