Common in labs and other areas where hazardous chemicals are present, these neutralizers bring the pH level of a spill back to within a neutral range. You'll know when the process is complete when the ,neutralizer, changes color.. In addition to pouring liquid and powder neutralizers onto spills, you can use them as an additive in processes such as deionized water systems and ,wastewater, tanks to ...

Gypsum as coagulant for waste water treatment

If the system uses a lot of sulfuric ,acid, and uses ,lime, as a ,neutralizer, and doesn't use any other coagulating agent, then one might argue that gypsum (calcium sulfate, the reaction product of ,lime, or calcium hydroxide and sulfuric ,acid,) is the coagulant.

Two uses of slaked lime (Ca (OH)2) are as follows: (i) Slaked lime gets used commonly as an acid neutralizer and an agent of pH-regulation in water and soil. (ii) For the purpose of serving as the accelerator in rubbers, slaked lime gets used as filler material in plastics and rubber." kvargli6h and 20 more users found this answer helpful.
