Carbon dioxide reduction in the ground waters in a baffled degasifier

Summary

The results of investigating carbon dioxide reduction in the ground waters of Tyumen Region in a bubble degasifier with horizontal baffles are shown. The efficiency of carbon dioxide removal is 70–75%. To intensify dissolved gas stripping a bubble degasifier design equipped with horizontal guide rails has been offered where the increase of the air utilization factor is ensured by modifications in the structure and route of air bubbles movement in water. Calculated relationships for determining the required number of baffles in the degasifier and residual concentration of carbon dioxide at 20 m/h countercurrent flow are identified. A nomograph for determining residual concentration of carbon dioxide together with procedure of designing the baffled degasifier are given.

Stabilization treatment of underground waters in the Tyumen North Region

Summary

The necessity of stabilization treatment of underground water used for potable water supply of the Tyumen North settlements is substantiated. The expediency of adding alkaline agents in the process of stabilization at the existing water treatment facilities in particular, is shown. Caustic soda is recommended as a stabilization agent. The in-process tests were carried out with water from Novomikhailovsk and Altymsk aquifiers that are most often used for potable water supply in the region.
