Wastewater treatment

The use of polymer flocculants represents the state of the art in municipal as well as industrial wastewater plants and in biological or chemical wastewater treatment.

Principles of chemical watewater treatment

Chemicals such as splitters, coagulants and adsorbents are often used in wastewater treatment. In the first step, micro flocks are produced by
means of coagulation with POLY SEPAR® CFL. In the second step, the micro flocs are enlarged according to the dewatering aggregate by using coagulants, which are mostly in ready to use solutions. As an alternative to this, adsorbents tailored to each application case can also be used during batch treatment.

Chemicals for the preconditioning of wastewaters

Many different products can be used to pretreat wastewater at the source, i.e. before it is discharged into public sewage systems:

Coagulation aids: inorganic metal salts as well as organic polyamines and PolyDADMACs serve as primary flocculants
Polyer flocculants: for conditioning prior to sludge thickening and dewatering
Emulsion breaking: to remove emulsified oils and fats
Adsorbents: to bind small amounts of residual oils or other light contaminants, for example dyestuffs
Charcoal and bentonite: for COD-reduction
Defoamers: prevention and removal of floating sludge
Deaerators: degassing of pulp
Heavy metal precipitants: especially for the elimination of nickel and copper
Crystallization inhibitors: for the prevention and removal of pipeline deposits (MAP or calcium compounds)

Reduction of sulphates and conductivity

Our newly developed product POLY SEPAR® CFX 2022 can effectively reduce the sulphate content and at the same time the conductivity in the wastwaters.
