Performance Chemicals


As process chemicals, additives for retention and dewatering bring about an optimal use of the applied raw materials and thus make an increase of the speed of the paper machine possible. Flocculants are mainly applied for the treatment of waste water, for the purification of white waters and for the dewatering of sludge. Apart from powder products, polymers are offered in liquid formulations which can vary considerably as far as character and density of charge as well as molecular weight are concerned.
