Methods of Struggle with Consequences of Colmatage and Corrosion of Water-Intake Well Equipment

Summary

The main problems encountered in the process of operation of water-intake wells are corrosion of water-lifting equipment and development of colmatage processes in the filters and in the zones of aquifers near the filters and, as consequence, decrease in output. One of the most acceptable variants of solving this problem is the use of glass-plastic pipes and polymeric filters. The experience in the use of up-to-date non-corrosive materials, the regeneration of wells using the reagent method making it possible to increase their output and to prolong the operation time is considered.
