Conclusions

The possibility of cleaning up wastewater from nonionic surface-active substances (NSAS) by the flotation method (foam separation) has been demonstrated under experimental conditions.

It has been found that the main factor which affects the degree of extraction of NSAS from wastewater is the ratio between the berol-visko 314 and the PEG-35. With decrease in the proportion of PEG-35 in the wastewater, the degree of extraction of berol-visko 314 rises to 80% at a flotation time of not over 60 min.

A calcium ion content of up to 950 mg/liter in wastewater exerts no effect on the degree of extraction of the NSAS.
