Potential Use of Saline Wastewater for the Agglomeration of Fluidized Fly Ash

Abstract

Experiments carried out within the research aimed to determine the influence of saline water on the properties of additivated granulate through interpreting extraction tests. Two types of mixing water of different degrees of mineralization were tested. Raw untreated water was used as a control sample. In assessing the potential use of saline water in the agglomeration of fluidized fly ash, aqueous extracts of fluidized-bed granulate mixed with water were subjected to analyses in accordance with valid legislation and standards. Based on the findings we identified their suitability for subsequent use. The main aim of the experiment was to compare the extraction test results of crushed and uncrushed granulate, which more or less fulfilled prerequisites of the intended testing. According to the obtained results it can be clearly seen that the mixing of salty water is recommended for use in the manufacture adducted granulate regardless of whether it is adducted granulate crushed or uncrushed, moistened raw untreated or salty water.
