Treating Acids & Alkalies in Industrial Wastewater
Treating Acids & Alkalies in Industrial Wastewater

The neutralization of, acids, and alkalis often produces a solid, residue, that may also be toxic in nature. In few cases, gases are evolved that require treatment for the gas stream., Waste, streams containing hard ions, readily loses its hardness through de-ionisation process in the accumulation of, precipitated, calcium and magnesium salts.
