What could be the cause of higher adsorbent dosage resulting in lower adsorption capacity of fluoride?5 answersThe cause of higher adsorbent dosage resulting in lower adsorption capacity of fluoride can be attributed to several factors. Firstly,states that the adsorption removal of fluoride decreases with an increase in fluoride concentration. This means that as the concentration of fluoride in the solution increases, the adsorbent becomes saturated more quickly, leading to a decrease in adsorption capacity. Additionally,andmention that the presence of other anions such as sulphate, chloride, and nitrate in the solution can reduce the removal capacity of the adsorbent. These anions compete with fluoride for adsorption sites on the adsorbent, thereby reducing the overall adsorption capacity. Furthermore,also indicates that the adsorption removal decreases with an increase in temperature, suggesting that higher temperatures may hinder the adsorption process and result in lower adsorption capacity. Overall, these factors contribute to the decrease in adsorption capacity of fluoride with higher adsorbent dosage.
What is the fineness of drinking water treatment residue?2 answersDrinking water treatment residue (DWTR) exhibits varying fineness depending on the treatment method used. Oxygen-limited heat treatment can enhance the fineness of DWTR, increasing its specific surface area (SSA) and total pore volume (TPV). The treatment also leads to the formation of metal oxides with high stability, such as amorphous Al/Fe oxides. On the other hand, ozone treatment has limited effect on the fineness of DWTR, with minimal changes observed in its physicochemical properties. Overall, the fineness of DWTR can be improved through oxygen-limited heat treatment, resulting in increased SSA and TPV, as well as the formation of metal oxides.
