Fundamental Study For The Field Tests On The Airlift

Abstract

Purification of water in the slack water reach of rivers and lakes is one of important problems. The purification by means of airlift may be most favorable, andin order to apply such apparatus for practical use, the intensive laboratory tests and hydraulic analysis are made. Based on the results of the fundamental study, the dimensions of the apparatus are decided and field tests are made. The results obtained in the field are acceptable.
