Free from iron, Non Ferric Alum (Non Ferric Alum Sulphate) Lumps are known for their hygroscopic properties. These have 1.69 specific gravity and their dehydration temperature is 86.5 degree C. Offered lumps easily dilute in water, alkali and acid. Their water based solution is acidic by nature. These are required for treating waste water as part of flocculation and precipitation procedures. In paper industry, these are needed to reduce holes and in strengthening paper sheets.
