Cloudy Alum – Premium Coagulant for Water Treatment, Agriculture & Industry | BTJ Group
Cloudy Alum, also known as Aluminium Sulfate or Potassium Aluminium Sulfate, is a widely used chemical compound in water treatment, agriculture, textile, paper, and leather industries. Unlike clear alum, Cloudy Alum has a milky or opaque appearance and is favored for its effective coagulation properties.
At BTJ Group, we supply high-quality Cloudy Alum in both lump and powder forms, ideal for use in industrial, municipal, and household applications.
✅ What is Cloudy Alum?
Cloudy Alum typically refers to:
Aluminium Sulfate (Al₂(SO₄)₃)
Potassium Aluminium Sulfate (KAl(SO₄)₂•12H₂O)
It appears as cloudy white or grayish-white crystals, usually in lump or stick form, and differs from clear alum by its opaque appearance and broader industrial utility.
Key Properties of Cloudy Alum
Appearance: Milky white to grayish-white solid, in lump or powder form
Solubility: Easily dissolves in water to produce a mildly acidic solution
Function: Strong coagulant, effective at binding suspended solids
Odor & Taste: Odorless and tasteless
Texture: Brittle and breakable in solid form
Cloudy Alum in Water Treatment
Cloudy Alum is most well-known for its use in clarifying water. When added to turbid water, it binds with suspended particles such as mud, dirt, algae, and organic matter, causing them to settle at the bottom.
Applications:
Municipal Waterworks: Used in water treatment plants to purify drinking water
Household Water Use: Traditional method for clarifying well or pond water
Wastewater Treatment: Ideal for industrial effluent settling prior to discharge
Household Uses of Cloudy Alum
Precipitates impurities in groundwater or well water
Clarifies water for drinking, cooking, or washing vegetables & seafood
Reduces fishy odors when cleaning seafood
Traditional and affordable water purification method in rural areas
Industrial Applications of Cloudy Alum
Textile Industry: Acts as a mordant to fix dyes during fabric processing
Paper Industry: Enhances fiber bonding and improves paper quality
Leather Tanning: Softens leather and improves dye absorption
Firefighting Products: Ingredient in certain fire-extinguishing compounds
Industrial Wastewater Treatment: Neutralizes particles before filtering processes
Agricultural Uses of Cloudy Alum
Pond Water Treatment: Clears murky water in fish farms, reducing algae buildup
Soil pH Control: Helps lower soil pH in alkaline soils
Fungal Protection: Prevents fungal infections in plants
Plant Strengthening: Enhances plant resistance when applied regularly
Cloudy Alum in Personal Care & Medical Applications
Natural Deodorant: Long-lasting odor control when applied to underarms or feet
