Environmental protection

Calcium hydroxide plays an important role in environmental protection. It can be used to treat waste water and waste gas and purify the environment. Calcium hydroxide can chemically react with organic matter and heavy metal ions in wastewater, making it insoluble in water, so as to achieve wastewater treatment and purification. In addition, calcium hydroxide can also be used to absorb and neutralize harmful substances in exhaust gas, reducing pollution to the atmosphere.
