Calcium carbonate scale on a piece of pipe. Excessively hard water will nearly always have to be softened in order to protect the water treatment plant equipment and piping systems. At a hardness of greater than 300 mg/L as calcium carbonate, scale will form on pipes as calcium carbonate precipitates out of the water.
Precipitation softening accomplished at ambient temperatures is referred to as cold lime softening. When hydrated lime, Ca (OH) 2, is added to the water being treated, the following reactions occur: If the proper chemical control is maintained on lime feed, the calcium hardness may be reduced to 35-50 ppm.

Ultra-dry calcium carbonate particles, a method for drying calcium carbonate particles and also the use of the resulting dried calcium carbonate as a flow property regulating agent in sealing compounds or adhesive compositions. The calcium carbonate particles are dried with microwaves. The drying can take place in a continuous belt apparatus, a batch treatment apparatus or a rotary-tube ...
Precipitated calcium carbonate preparation began with the lime slaking process. Lime and water were mixed with a high-shear mixer for 10 min to form Ca(OH) 2 (slaked lime). The initial water temperature was 50 °C, and the lime-to-water ratio was 1:5.
produce precipitated calcium carbonate (PCC). Fig. 2 (a) and (b) show raw eggshell and the peeled yolk membrane from fowl eggs respectively. II. PCC SYNTHESIS Precipitated calcium carbonate is currently produced via three different processes; the lime soda process, the calcium chloride process and the carbonation process. A.

Carbon dioxide + calcium hydroxide (precipitated process) Calcium chloride + sodium carbonate (precipitated process) price 3 inorganic-chemicals calcium-carbonate 1 3 397 Calcium Carbonate (a.k.a. CaCO3) is a non-toxic and odorless inorganic salt, commonly found as a white mineral (calcite) which occurs naturally in chalks, limestones and marbles.
Precipitation of calcium carbonate (lime) is a common clogging problem in microirrigation systems. Water with a pH of 7.5 or higher and a bicarbonate level of at least 2 meq/l (120 ppm) is susceptible to calcium carbonate precipitation if comparable levels of calcium are present naturally in the system or if a compound that contains calcium is injected into the system.
According to the process, limestone is burned at a high temperature to form calcium oxide and, thereafter, calcium carbonate is formed from calcium oxide in the presence of water and carbonate ions and the formed calcium carbonate is recovered. The formation of the carbonate may be performed by carbonating calcium oxide with carbon dioxide gas in the presence of water or water vapour, or by ...
