Activated Alumina Supplier in Bangladesh.

Description

Activated Alumina Supplier in Bangladesh.

Activated Alumina:

Activated Alumina (Al₂O₃·xH₂O) is a highly porous aluminum oxide adsorbent widely used for water treatment, gas purification, air drying, and industrial adsorption applications in Bangladesh. It is produced by controlled dehydroxylation of aluminum hydroxide, creating a large surface area with strong adsorption capacity for moisture, fluoride, arsenic, acidic gases, and other contaminants.

Key Features of Activated Alumina:

1. White, spherical, non-toxic, and odorless beads.
2. High surface area and excellent adsorption efficiency.
3. Insoluble in water and alcohol.
4. High mechanical (crushing) strength.
5. Superior moisture and contaminant removal capacity.
6. Stable structure – does not crack or disintegrate after water absorption.

Available Sizes:

1–3 mm | 3–5 mm | 4–6 mm | 5–8 mm | Custom sizes

Common Applications by Size:

1. Drinking water treatment (fluoride & arsenic removal): 1–3 mm
2. Industrial water purification: 3–5 mm
3. Compressed air & gas drying: 3–5 mm / 4–6 mm
4. High-flow or low pressure-drop systems: 5–8 mm

Applications of Activated Alumina:

A. Gas Purification & Air Drying:

Activated alumina is widely used as a desiccant and adsorbent for:

1. Compressed air, natural gas, nitrogen, oxygen, hydrogen, refrigerants
2. Moisture removal to achieve dew points up to −40°C or lower
3. Removal of acidic gases such as HF, H₂S, SO₂, HCl
4. Sulfur and volatile contaminant removal from refinery and process gases

Benefits:
High adsorption efficiency, chemical stability, regenerable, long service life.

B. Water Treatment Applications:

Activated alumina is a proven solution for drinking water and industrial water treatment in Bangladesh.

1. Fluoride removal (prevents dental & skeletal fluorosis)
2. Arsenic (As³⁺ / As⁵⁺) removal
3. Lead, selenium, and heavy metal removal
4. Silica removal in boiler feed water and RO systems
5. Regenerable using acidic or alkaline solutions

C. Food & Beverage Industry:

Food-grade activated alumina is safe, inert, and taste-neutral, used for:

1. Potable water treatment in food & beverage plants
2. Bottled water, soft drinks, breweries, dairy, juice processing
3. Drying food-grade gases (CO₂, nitrogen, compressed air)
4. Sugar decolorization, edible oil refining, ethanol drying

 

D. Pharmaceutical Applications:

Pharmaceutical-grade activated alumina supports USP, EP, BP, and GMP compliance.

1. Purified Water (PW) & WFI pre-treatment
2. Drying of pharmaceutical gases
3. Chromatography separation of APIs
4. Catalyst support for pharmaceutical synthesis
5. Solvent purification (ethanol, methanol, acetone, hexane)
6. Clean-room air and exhaust gas purification

Why Choose Activated Alumina?

1. Excellent adsorbent and desiccant
2. Suitable for batch and continuous systems
3. Regenerable and cost-effective
4. Long operational life
5. Trusted solution for water, gas, food, pharmaceutical, and industrial sectors
