IDRAFLOT® flotation units

IDRAFLOT® flotation units

An innovative and effective water mixing device

IDRAFLOT® are intended to assure a perfect mixing of the waste with saturated water and an uniform distribution of the water flow along the entire surface of the unit made possible by their innovative modular design.

IDRAFLOT® flotation units have mixing volumes intended to optimize the process and the unit’s total capacity.

IDRAFLOT® units allow for enhanced thickening and clarification performance. This creates an increased removal of insoluble COD, suspended solids, and FOG (fats, oils, and grease).

IDRAFLOT® flotation units are protected by three patents. They are intended to assure a perfect mixing of the waste with saturated water and a uniform distribution of the water flow along the entire surface of the unit.

It is provided with lamellar packs, to achieve high treatment capacity compared to its compact size, telescopic level adjustment to optimize the sludge extraction with dry matter up to 8%.

The saturation system warrants a complete and even saturation free from formation of big bubbles.

IDRAFLOT® are very compact flotation units which boast the lowest chemicals consumption within the category.

How it works

Flotation consists of separating solids from the water phase by attaching the solids to fine air bubbles to decrease the densityof the particles which float instead of sinking. The rising solids are called the “float” and are skimmed off the surface and further processed in the sludge train.Chemicals can be added to improve the separation: first for coagulation and then for flocculation.
The type of flotation used by IDRAFLOT® is the Dissolved Air Flotation (DAF), in which the suspension is saturated with air at high pressure. Bubbles are released to the water and will attach to the suspended solids.The bubbles from a DAF system are much smaller than in other types of flotation systems and better adhere to the solids.This makes IDRAFLOT® DAFs one of the most efficient flotation options of wastewater treatment.
