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
