Abstract
This paper presents a set for testing industrial wastewaters in technical scale using physicochemical methods of their pretreatment at the
source of their origin with flotational precipitation of flocculated and thickened dispersed fractions. The installation constructed on a
mobile pallet of capacity up to 1.0 m3
/h is equipped with a central, cylindrical-conical process reactor with a slow-speed frame agitator (or
with an optional flotator and a surface flotate skimmer), tubular reactors where chemical reagents are dispensed from their preparation and
dosing stations, as well as with the process nodes to conduct flotation techniques with induced air (IAF) and/or dissolved air (DAF)
according to the own invention or with the assistance of oxidation (OxIAF and/or OxDAF). Using this test set, different methods of
physicochemical pretreatment can be optimised by means of i.a.: coagulation, chemical precipitation or deep oxidation and final
separation of the dispersed phases with mentioned flotation techniques supported by oxidation with e.g. hydrogen peroxide.
Keywords: mobile testing set; industrial wastewater pretreatment; OxIAF and OxDAF type flotation.
