Water treatment, papermaking,  printing and dyeing,  pigment,  fire fighting equipment, food additives, chemicals and wood  preservation, medicine and Cosmetic,textile, etc.
1) In water treatment, its used as flocculants for purification of drinking water and wastewater treatment by settling of impurities by means of precipitation and flocculation.
Because, after dissolved in water, can make the small particles and natural colloidal particles coalesce into large floc,thus to remove them from water, so as the water and wastewater coagulant.
2) In the paper industry, used as a paper sizing agent of paper, to improving paper quality(reducing spots, enhance the water resistance, permeability, increase the hardness, etc.
3) In printing and dyeing industry, as anti-seepage agent mordant and printing.
Pigment  industry  for  the production of chrome yellow and precipitant, at the same time, as solid color and fillers.
4). In fire protection industry, used as retention agent of foam fire extinguisher,making with baking soda and foaming agent.

 

Ammonium sulfate - Wikipedia

Ammonium sulfate decomposes upon heating above 250 °C, first forming ammonium bisulfate. Heating at higher temperatures results in decomposition into ammonia, nitrogen, sulfur dioxide, and water. As a salt of a strong acid (H2SO4) and weak base (NH3), its solution is acidic; pH of 0.1 M solution is 5.5
