Process Dosing chemical auxiliary products
Precipitating agents such as Al, Ca and Fe salts form separable compounds, that have little soluble qualities, by way of a chemical reaction.
Flocculants, positively loaded such as Fe and aluminium salts occur with negatively loaded particles to create larger flakes (coagulation).
Flocculants (FHM) bring about by way of networking mechanisms the growth of the flakes created by precipitating agents and flocculants (flocculation). Structures are created that improve the sludge dehydration.
Largely synthetic water-soluble polymers are used as organic auxiliary aids. Combined with inorganic precipitating agents they work as flocculating agents. Loaded ionic polymers are described as polyelectrolyte. Polymers or copolymers are largely used on the basis of acrylamide.
Acids and alkaline solutions are used in the case of neutralisation and adjustment of the pH value (iron/calcium conditioning).
seepex progressive cavity pumps convey and meter chemical auxiliary aids. Ideal pH values are set up by way of the integration in process controls and inaccurate metering of auxiliary aids is avoided.
