As in other chemical water softening technologies, the objective of the lime–soda ash process is to precipitate polyvalent cations from solution by pH adjustment. In water treatment applications, Ca2+ and Mg2+ are the two major cations of concern, though Fe2+, Fe3+, Al3+, and Mn2+ may ...
6) lime-soda ash softening 石灰苏打软化(法)补充资料:电磁原理"水处理"和"水软化"的区别? 在软化过的水中,钙、镁等成分被钠所替代;而在被(经特定电磁原理)处理过的水中,只是钙离子的晶体结构被改变,使其以一种很小的颗粒状态溶于水中。这两种方法都能防止水管内的水垢生成。 在被"处理"过的水中,对...

Caustic soda is widely used in wastewater treatment for pH adjustment and chemical precipitation. It provides an instant neutralizing reaction, but it can be dangerous for people working with it and can also harm the treatment process and the environment. ...
The soda content of the lime mud has a significant effect on its aggregating properties during the reburning operation and is typically controlled to less than 1% sodium oxide. The hot end of the kiln is typically maintained at 1150–1250°C by firing oil or gas. Without reclaiming heat ...
