Activated charcoal BAU-A

What Is BAU Activated Wood Carbon?

Activated carbon has a developed porous structure and is used as an adsorbent — a material on whose surface certain substances from liquid or gaseous media can be retained. Treatment efficiency depends on the substance to be removed, its concentration, contact time, temperature, flow rate, and other process parameters.

Product Options

How to Choose the Particle Size

BAU-A — 1.0–3.6 mm
The coarsest of the available options. It is suitable for granular filter and adsorbent beds where the medium passes through a layer of activated carbon. All other conditions being equal, a coarser fraction forms a more permeable bed than a finer one.
BAU-MF — 0.5–2.0 mm
A finer granular fraction. It can be selected when the equipment design or technological process requires a smaller particle size. As particle size decreases, contact conditions with the medium change and resistance to flow through the bed may increase.
Powdered Activated Carbon — 0–0.5 mm
The finest available fraction. It can be introduced directly into the medium being treated and subsequently separated according to the process technology. It can also be used in adsorption/filter layers and materials designed to retain fine carbon particles. Possible applications include use with filter paper, woven, nonwoven, or other permeable retaining materials compatible with the specific process.

Applications

• adsorption treatment of aqueous and other liquid media;
• filter and adsorbent beds;
• industrial treatment of solutions;
• reduction of substances that can be adsorbed by activated carbon;
• adsorption/filter layers and materials;
• use as an adsorbent component in industrial mixtures and products.

Actual performance depends on the composition of the medium, the properties of the substances to be removed, and the operating conditions of the process.

What to Consider When Choosing

Choosing a fraction simply on the principle that “finer is always better” is incorrect. Smaller particles may change the contact conditions with the medium, but they also affect hydraulic resistance of the bed and the risk of fine-particle carryover.

• composition of the medium being treated;
• substances to be removed;
• design of the filter or equipment;
• flow rate and acceptable hydraulic resistance;
• method used to retain the carbon particles;
• required contact time with the adsorbent.

Packaging and Storage

Packaging — 10 kg bag. Store in closed packaging in a dry place, protected from moisture and foreign contamination. When handling fine material, dust generation and inhalation should be minimized, and appropriate personal protective equipment should be used according to the working conditions.

Buy BAU Activated Wood Carbon

Novohim offers BAU activated wood carbon in 10 kg bags with a choice of particle size: BAU-A 1.0–3.6 mm, BAU-MF 0.5–2.0 mm, or powdered activated carbon 0–0.5 mm. The fraction should be selected according to the application technology and the design of the filtration equipment.

Frequently Asked Questions

What is the difference between BAU-A and BAU-MF?
For this product offer, the main selection criterion is particle size: BAU-A — 1.0–3.6 mm; BAU-MF — 0.5–2.0 mm.
What is the finest available fraction?
Powdered activated wood carbon — 0–0.5 mm.
Can the 0–0.5 mm fraction be used in a filter bed?
Yes, provided that the filter design retains the fine carbon particles and maintains acceptable resistance to the flow of the medium.
Is a finer fraction always better?
No. Particle size affects both contact conditions with the medium and resistance to flow, as well as the possibility of particle carryover.
What is the packaging size?
All three options are supplied in 10 kg bags.
