Preparation of underground water with a high content of iron and manganese for drinking water supply

Abstract

When using groundwater for drinking water supply to villages, there is often a need for their deferrization and demanganization. Water with excess iron and manganese content has an unpleasant taste and causes diseases of the cardiovascular, skeletal and reproductive systems of humans. High water hardness leads to atherosclerosis and urolithiasis. The purpose of this study is to develop a technological scheme for the preparation of drinking water from underground sources for water supply to small populated areas in Siberia. The research results were obtained by conducting experimental studies. The research was carried out at an experimental installation in the working village of Ordynsky, Novosibirsk region, for the purification of natural groundwater from wells. As a result of research, it was established that preliminary aeration and reagent treatment of water followed by filtration on 2-stage clarification filters loaded with the new Diamix Aqua filter material ensures the drinking quality of purified water. A new technological scheme for water treatment for the drinking water supply of the village has been developed, including new equipment, materials and reagents, with the reuse of rinsing wastewater and disposal of water sludge.
