Pro-Cal is the first step in treating any field. Before fertilizer is applied or seed is planted, it is important to prepare the soil. 95% of soil naturally has a low soil pH. Low pH leads to lost fertilizer, bound up nutrients, slowed growth, and. Pro-Cal® can be applied through standard ground or …
In the second step (Reaction Tank #3), lime is typically used for the precipitation reaction. In this flow diagram, a process known as high density sludge (HDS) is employed to help promote precipitation. The heart of the HDS process is the pH in the HDS or densification tank which needs to be at a …

From the silo, the burned lime is either delivered to the end user for use in the form of quicklime, or transferred to a hydrating plant where it is reacted with water to produce slaked lime. A flow chart for a hydrated lime manufacturing process:
Precipitated Calcium Carbonate. PCC stands for Precipitated Calcium Carbonate—also known as purified, refined or synthetic calcium carbonate. It has the same chemical formula as other types of calcium carbonate, such as limestone, marble and chalk: CaCO3. The calcium, carbon and oxygen atoms can arrange themselves in three different ways, to form three different calcium carbonate minerals.
Lime and limestone play a significant role in the removal of pollutants from the flue-gas streams of coal-fired power plants, incinerators and industrial facilities.
