FLOTATION UNITS WITH DISSOLVED AIR ALPHA / ALPHA+ Flotation units with dissolved air allow to accelerate the separation of water and suspended solids. Compact and simple of use, they make it possible to recover at the same time floated and settling particles, and produce rejections with strong content of dry matter. The ALPHA flotation units are special designed to treat high polluted wastewater. Therefore the ALPHA units are very suitable as pretreatment step for removing of the suspended solids, fats, oil, grease and other floating materials in the waste water. Especially in combination with coagulation / flocculation the ALPHA unit can achieve a high rate purification of waste water. With some modifications the ALPHA Unit can also be used as sludge thickener, oil separator, tertiary treatment, etc. Operating principle Outlet Inlet Several injection points of white water Air injection Discharge of floated matters Discharge of settling particles Advantages DP27GBA Very suitable for highly polluted wastewater Stainless steel construction Skimmer with static sludge thickener which results in a high dry solids load of the floating sludge.

FLOTAT ION  UNITS  WITH  DISSOLVED  AIR   ‐  ALPHA  /  ALPHA+  

Flotation units with dissolved air allow to accelerate the separation of wa‐ter and suspended solids.  Compact and simple of use, they make it possible to recover at the same time floated and settling particles, and produce re‐jections with strong content of dry matter.   The ALPHA flotation units are special designed to treat high polluted waste‐water. Therefore  the ALPHA units are very suitable as pre‐treatment step for  removing of  the  suspended  solids,  fats, oil,  grease  and other  floating materials  in the waste water. Especially  in combination with coagulation / flocculation  the ALPHA unit  can  achieve  a high  rate purification of waste water.  With some modifications the ALPHA Unit can also be used as sludge thicke‐ner, oil separator, tertiary treatment, etc.  

Operating principle 

Outlet 

Inlet 

Several injection points of white water 

Air injection 

Discharge of floated matters 

Discharge of settling particles 

Advantages 

DP‐27‐GB‐A 

Very suitable for highly polluted wastewater 

Stainless steel construction  

Skimmer with  static  sludge  thickener which  results  in  a high dry solids load of the floating sludge. 

Equipped with  a unique  self‐cleaning  aeration  system  to prevent clogging  

The ALPHA units are designed to achieve a complete lami‐nar flow through the unit, this way optimal separation of the particles takes place 

 

Easy in maintenance. 

Low cost maintenance 

Recovery of  solids  on  the  surface  and of  the bottom of the flotation unit 

Possible use of additives (coagulation and/or flocculation) 

ALPHA units can be transported in standard sea container
