FLOTATION UNIT WITH DISSOLVED AIR ‐ GAMMA 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 GAMMA flotation units are special designed to handle large flows of relative high polluted wastewater. Therefore the GAMMA 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 GAMMA unit can achieve a high rate purification of waste water. With some modifications the GAMMA unit can also be used as sludge thickener, oil separator, tertiary treatment, etc. Advantages Operating principle DP‐29‐GB‐A Several injection points of white water Discharge of floated matters Outlet Inlet DIscharge of settling particles Air injection 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 GAMMA units are designed to achieve a complete laminar 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) GAMMA 225 and 300 units can be transported in standard sea container
