A method and device is provided for combining various forms of flotation techniques to achieve a very high degree of purification of waste water while energy consumption is maintained low.

Combiflotation for purification and disinfection of waste water

The invention provides a device to purify waste water by a two-step procedure containing an electroflotation unit and an electrical disinfection unit integrated into the same overall construction. Characteristic to the construction is that the said two units have a common anode and two individual cathodes which can be in different potentials in respect to the common anode.

Construction of devices for purification and disinfection of waste water with electrical current

An apparatus for separation of solids in froth is presented. The apparatus includes: a housing ( ), establishing a chamber ( ) for flows of liquid and solid material and a froth bed ( ) on the liquid; feeding means ( ) for getting incoming material to be separated in contact with said froth bed ( ); discharging means ( ) for solid material near the bottom ( ) of said housing ( ); aerator means ( ) under the liquid surface ( ) for creating bubbles and thus forming said bed of froth ( ) and generating movement on the bed of froth ( ); means for discharging froth from the housing ( ) including at least a froth outlet ( ). The apparatus is characterized by a surface ( ) connected to said feeding means ( ) so as to reduce the vertical speed component of the material being fed with the feeding means ( ) from above said froth bed in and on to said froth bed ( ).
