Description

Continuous Upflow Volume Filter Rapid sand filter for large flow applications High operational reliability Low operating costs Minimum maintenance Continuous deep bed filtration with sand bed heights between 1 and 2 meter fulfils the high requirements on effluent quality. In combination with a physical/chemical treatment stage (precipitation/flocculation) also dissolved material (e.g. orthophosphate) iscarried over into the solid phase and separated in the filter. Colloidal material is agglomerated to filterable material is flocculated to filterable material. Measurements have shown that the CONTIFLOW® significantly reduces the number of germs. In case of increased disinfection requirements, installation of a subsequent UV disinfection unit is possible due to the low concentration of solids in the filtrate. The system is available as a steel tank design (type "SS") or concrete basin design (type "C") for large flow applications. The concrete basin design consists of several modules. Their number can be tailored individually to particular flow and process requirements – up to 12 modules. The rough surface of the grit paricles allows the growth of biomass. The nutrients contained in the inflow, such as nitrogen, are eliminated through biological degradation. Iron/manganese can be carried over into the solid phase by preceding oxidation and separated by filtration. Elimination of nitrogen and degradation of organic substances is achieved by means of the biologically intensified filtration. The Sandfilter is also used as a reactor for nutrient reduction with chemical phosphorus elimination through precipitation.
