shallow air flotation machine for paper making factory, 25ton-600ton/hour

I.   Introduction

Shallow air flotation machine are designed with ‘shallow tank theory’ and ‘zero velocity principle”. Retention time only 3-5 minutes.The machine has wide range of application, can be used in paper making(white paper recovery),  lake water source water plant algae removal and turbid descending.Industrial wastewter treatment such as petrochemcial , textile, printing and dyeing,electroplating, tanning, food industry,etc

 II. Working Principle

 Shallow air flotation works by intense micron bubbles into the sewage, Released in the raw water pipeline at normal pressure,make the impurity, floc adhere to each other in the pipeline.The formation of the floating body is far less than the proportion of water, rapid ascent to the surface by buoyancy in the tank,to meet the solid-liquid separation in this method. 

III. Main Advantages  

 - DAF single unit capacity can be 1800m3/hr 

- tank depth only 600-900mm

- Short retention time 3-5 minutes,

-- little chemical cost.

- core equipment ”zero velocity” principle
