Abstract
The article presents carbonization as a method of waste management from the brine sodium-lime method. It was compared with the previously obtained results for the lye-sodium one. Within it, the fltration and washing times were contrasted for treated and non-carbonised samples. For this aim potentiometric titration analysis was used to determine the precipitation's basic components and by-product brine. Scanning electron microscope with energy dispersive X-ray spectrum and diffractographic analysis were used for morphology analysis what allowed to determine the tested samples' composition. It was found that despite significant differences in the time of washing and filtration, the time of these processes is shortened after the suspension has been exposed to carbon dioxide. In both cases the composition allows the waste brine to be recycled to the purifcation processes and the mixture of calcium and magnesium compounds become alternative raw material. It turned out that in both methods it is possible to utilize the suspension formed.
