Alum is a semi-transparent glass-like solid substance with a sweet and astringent taste and a very dry nature. When some alum is mixed with polluted water, the impurities in the water stick together and become heavy and accumulate under the water, leaving clean water on top. Floods and tidal waves in Bangladesh continue to occur in epidemic form. Then there is an acute shortage of clean drinking water. The World Health Organization has identified alum as the cheapest, most effective and suitable disinfectant for Bangladesh. Excessive consumption of alum can cause stomach pain and even poisoning. #iron_free_water #freshwater
