Theory and Process ECF® Technology
The central idea behind the Electroflotation ECF® Technology consists of the construction of particularly sweet purification systems, that are able to exploit the action of the best existing precipitating agent (the electron!) In association with the particular physical effect generated by 'energetic development of micro-bubbles (in the molecular state) within the solution. The heart of the Electroflotation Redox®System system is represented by an electrolytic cell into which is fed the solution to be treated (NONE pH correction if between 4.5 and 8.5 at the entrance of the cell) .The control system and control of ECF® Technology applies an appropriate voltage to the electrodes of the cell system essentially consisting of Cathode (iron or other material which eg. titanium) and anodes in aluminum alloy (or other material). The geometry of the cell and that of the electrodes, their number and the sequence of placement depend essentially on the particular characteristics of the solution to be treated and therefore are specifically calculated and designed according to each individual case.
The previously described phenomena lead to the creation of a two-phase system :
Formation of a compact foam ( floated ) on the surface of the aqueous solution contained in an electrolytic cell that It is discharged in the mixing section .
The float and the precipitate - flocculated are subjected to filtration and drying to the mass can overthrow . In function of the pollutants treated in the process ECF® Technology the filtration will be in continuous or discontinuous
The mass of purified water that is located in output from this step is harvested and sent again in recycling , because of its chemical and chemical- physical characteristics allow the immediate reuse . From the point of view strictly chemical- analytical (which is what is most interesting from legislative and operational point of view ) , the main operating results are obtainable immediately :
Reduction of COD and BOD
Reduction of MBAS and BIAS surfactants
almost total reduction of Phosphates
Removal of oils and separating emulsified
almost total removal of heavy metals
Abatement of sulphides , nitrite and cyanides
remarkable bactericidal effect
