Conclusions
1. The effects of physical and hydrodynamic factors on the effectiveness of degassification of spent coagulation baths by spray plant has been investigated experimentally.
2. Regardless of the method of degassing, the spray plant operated satisfactorily without carry-over of spray from the settling bath at a linear air speed of 0.02–0.2 m/sec with a spray density of 100 m3(m2·h).
3. Most effective degassing (90–95%) was achieved with a low degree of residual pressure in the plant and with an additional air feed of 5 to 10 m3 for every 1 m3 of solution.
