As a natural product, calcium carbonate is the perfect solution for environmental protection applications. Calcium carbonate has a natural buffer effect and works as a pollution filter – it poses no health risks and is free of harmful chemicals.
As a natural buffer, calcium carbonate is used in water treatment to regulate the pH of natural water and drinking water and consequently protects the environment and human health. Calcium carbonate is used in sewage or waste water treatment and is used as a desulphurisation agent in flue gas treatment at coal-fired power stations, where it helps to convert the large amounts of sulfur dioxide into recyclable gypsum. Calcium carbonate can also compensate for the negative effects of acid rain and eutrophication. Controlled liming stabilises the pH of acidified soil and water so that new organisms can thrive.
Whether in drinking water, waste water and sludge treatment, flue gas desulphurisation or forest and lake liming, the use of calcium carbonate in environmental protection is growing year by year.
