Alum project information

Here are some details on the ALUM PROJECT
Alums are usually the double salts of ammonium, potassium or sodium sulphate with aluminium, chromium or iron sulphate, and are readily prepared by concentrating and cooling a solution containing molecular proportions of the component sulphate. Ferric alum mainly used in paper sizing and in water treatment. Demand for ferric alum is arising for making water more soft for drinking and industrial uses. Present production of ferric alum is insufficient to satisfy the demand and supply. It provides good scope to many new units to enter in this industry.
Plant capacity: 30 MT/Day
Plant & machinery: Rs. 50.00 Lacs (roughly)
Working capital: Rs. 75 Lacs ( approximately)

  • Experiencing a global shortage of natural sand, and environmental pressures, costs and a shortage has necessitated the manufacture of sand from quarried material
  • Manufactured sand, also called artificial sand, is being successfully used in the production of high quality concrete and asphalt around the world. Its superior shape puts it well within specifications imposed on sand for use in concrete production

    “Building with Grandson” from Doug Williams,

    An engineer talks about ...“What came to mind when answering the question, What inspires you to achieve awesomeness in engineering, was my grandson. In this picture, he asked me to help him build a model of the Tower Bridge for his 4th grade EDGE Program (a class for gifted students).  And thanks to grandma, I happened to have a picture of the build!”
