AVebe water purifiers
WISPROFLOC is the general name of three flocculating agents and flocculating aids: a non-ionic, a cationic and an anionic grade. These promote the flocculation by adsorption onto dispersed particles. In some cases, however, colloidal impurities are not fully flocculated unless a coagulating agent like lime, aluminium sulphate, iron sulphate or iron chloride is added to the water in advance. If coagulating agents already form a part of the process, the use of WISPROFLOC-grades may lead to an important reduction in the usual dosages of these agents.
WISPROFLOC-grades have a number of special properties:
-
They easily dissolve in cold water
-
They are non-corrosive
-
They are harmless to health
-
Their taste is neutral
-
They are effective in a wide pH range
-
Small doses of WISPROFLOC promote the sedimentation of dispersed impurities considerably
-
Even very small impure particles which are normally caught on the filters are precipitated in sedimentation basins. This means a substantial relief of filter action and faster water transport
-
Flocs formed by WISPROFLOC-grades are stable and will not form a slimy layer on the filter which could block the water passage
-
WISPROFLOC-grades increase the capacity of water purification installations considerably
Important application fields are:
-
Drinking water: The processing of surface water for conversion to drinking water
-
Factory water: Treatment of mill water - steamboilers, and process water - born from surface water
-
Industrial waste water: Treatment of waste water born from a.o. galvanic, metal processing industries, paper and cardboard mills, coal and ore mines and sugar mills
-
Effluent water: Treatment of effluent water and sludge suspensions.
