ABSTRACT
Water resources are the cornerstone of human survival and development, but in recent years, their quality has been seriously threatened. Traditional water purification techniques, such as the use of alum or activated carbon, are effective but have potential risks, such as excessive ingestion of aluminium ions. The purpose of this study was to evaluate the adsorption capacity of calcium chloride, activated carbon, sodium silicate and alum to pigment molecules and harmful ions in water under different environmental conditions. Through experiments simulating the sedimentation tank of a water purification plant, we found that the mixture of calcium chloride and sodium silicate performed well in removing pigment molecules and reducing water turbidity, with removal rates as high as 96% and 95.9%, respectively. The results show that the mixture of calcium chloride and sodium silicate has great potential in the field of wastewater treatment.
