In the case of pigment-containing waste water, complete decolourisation can be achieved using appropriate cationic or anionic flocculants. In the case of wastewater containing dyestuffs, a decision must be made on a case-by-case basis.
Anionic and cationic polyacrylamides of various molecular weights and charge strengths. Due to the long molecular chains they have a cross-linking effect and thus larger flocks can develop.
Defoamer based on silicone oil. Highly effective over a wide pH range. For the food sector or PET recycling, a product series is available that can be used for LFGB-compliant (formerly LMBG) processes.
