Unoil effectiveness research of setting tank on Oily sewage using Air Flotation

In order to use aerator on setting tank in practical production, we use air flotation to increase oil removal. The small imitated experiment research of setting tank linked with air flotation are applied, different technological parameters such as: aerated way, release way, reflux ratio and dosing concentration are considered beyond tests. As a result, when reflux ratio is among 15~20%, dissolved vapor pressure air-float measures can increase the better oil removal efficiency.
