Abstract
The article discusses methods for purifying natural and wastewater from heavy metals using zeolites and various filter materials. Heavy metals are characterized as priority pollutants of the aquatic environment, and the need for their removal from water is justified. The authors consider the physicochemical properties of zeolites, their ion exchange and sorption capacities, as well as the effectiveness of other loading materials, such as activated carbon. The main water purification technologies used to remove heavy metal ions, including filtration, sorption, and combined methods, are analyzed. The areas of application of these technologies in water treatment and wastewater treatment systems are considered. A comparative analysis of the effectiveness of various filter material is provided. Conclusions are made about the prospects for using zeolites and filter media to improve water purifications quality and ensure the environmental safety of water resources.
