DISSOLVED AIR FLOTATION

Sludge management usually has two main challenges:
1) where to put the sludge;
2) how to reduce sludge disposal costs.

FlotLife offers a fast-track technology solution to both of these problems. FDS is an innovative multi-disc screw press manufactured by FlotLife for dewatering all types of sludge. FDS reduces the weight and volume of sludge by dividing the sludge into liquid and solid components. As a result, the amount of sludge can be reduced up to 7 times.

Wastewater is pumped into a flotation tank or basin and hit with dissolved air causing microscopic bubbles adhere to suspended solids causing them lift to the surface of the water where it may then be removed by a skimming device and drained toward a sludge discharge tank. Not-floating solids sink to the bottom of the DAF tank from where they are discharged by an automatically controlled pneumatic drain valve.

The goal of dissolved air flotation is to create a system which successfully treats a wide range of suspended solids at a high rate of solids removal. Technology of dissolved air flotation includes a range of components like flotation tank (flotator), skimmer, feed distribution well, and back pressure pump, valve, and saturation (the bubbles generation) system.

For dissolved air flotation, FlotLife supplies full set of technological equipment along with system installation, training and support services.
