Effectiveness of removing heavy metals from groundwater

The author is conducting laboratory studies to determine a cost-effective method for filtering groundwater from heavy metals in the city of Moscow, where in the first stage, during the development of a pit, most of the soil metals are precipitated, followed by excavation, and the remaining heavy metals will be purified during processing for use for drinking purposes. Various water reuse technologies are also discussed, including mechanical, sorption, reverse osmosis, and UV purification. The experiment allowed us to compare the effectiveness of using a heat pump and reverse osmosis for water purification. The heat pump system has proven to be effective in removing metals. The author proposed a modified method of water purification in a complex solution to soil and groundwater pollution during the development of underground space that meets the standards, where the “water-steam-water” system operated on renewable energy sources. The possibility of using the proposed method in the construction of residential complexes and business centers using solar panels and lightweight versions of wind generators has been assessed. Overall, the experiment showed that a reliable water purification system may require additional costs, and preheating the water before purification can reduce energy consumption. This method can be effectively implemented using a comprehensive method for combating the pollution of underground space with heavy metals, where the development of soil can initially use microorganisms to precipitate most of the metals in the soil, which will later be used for phytoremediation, and water – for drinking purposes.
