Filter-grade diatomite for industrial buyers
A natural diatomite deposit is not automatically a filter aid. NAGTAR structures drying, classification and optional calcination so permeability and particle retention match the liquid process. Trial parcels first; recurring supply after the plant clears clarity and flow.

What is Diatomite?
Diatomite (diatomaceous earth) is a silica-rich sedimentary material used as a filter aid. Natural ore must be processed and tested for permeability and particle retention before it qualifies for industrial filtration.
US market focus
US food, beverage and industrial filtration plants buy grades that pass in-plant trials. We support that path explicitly — no claim that ore name equals filter performance.
Who buys this
Edible oil and industrial oil filtration
Performance trials on flow and clarity.
Beverage and food processors
Grade trials under plant hygiene and retention rules.
Filter-aid distributors
Samples into accounts already running diatomaceous earth.
Grade variants
Natural processed filter grade
General filtration
Dried and classified for permeability — still tested before programme.
Calcined / flux-calcined style grades
Higher-flow applications
Where calcination is part of the buyer’s qualified grade family. Confirmed explicitly.
From resource to grade
01.Diatomite ore
Deposit — not yet a filter aid.
02.Drying and classification
Particle and moisture control.
03.Optional calcination
When the filter grade family requires it.
04.Filter-aid grade
Permeability and retention confirmed for the process.
Standards and references often used in briefs
Cited as buyer specification guides — not as a certificate already issued on an unnamed lot.
Buyer filter performance methods
Plants specify permeability, clarity and retention tests. We align the trial to those methods on the candidate grade.
What we confirm before quoting
- Liquid process (oil, beverage, industrial)
- Permeability / grade family currently qualified
- Calcined or not
- Trial volume before programme
Typical inquiry fields
- Process and current filter-aid grade family
- Performance targets
- Trial vs programme volume
- Destination and packing
Path to a first programme
01.Process brief
What liquid, what failure mode.
02.Lab or plant trial
Flow and clarity.
03.Trial parcel
Executable first shipment.
04.Recurring filter programme
With multi-origin backup in the same grade family.
How we source Diatomite
Send the liquid process, permeability or grade family you use, volume and destination. We say whether a filter-grade path looks realistic.
Supply continuity
Algeria-first filter grades with alternate origins so a filtration plant is not stranded on one deposit or calcination line.
Trade and market context
Filter aids are bought on performance, not on geology marketing. Public trade data helps see import patterns; plant trials decide the order.

Technical specifications
Permeability, particle retention, moisture and composition are confirmed on the qualified lot. A natural diatomite label is not a filter-aid guarantee.
Logistics & packing
Bags, big bags or containers depending on grade and volume.
Bags and big bags are typical for filter aids. Format locked with the receiver.

Documents & inspection
Grade data plus commercial and export documents for the named destination.
Performance sampling can be arranged before shipment when the contract requires it.
Commercial terms & export
Quoted as a named filter grade into a named process. Trial lots may precede a full programme.
