Avslå sigevannsbehandling
Søppelvann produseres ved gjæring, regnskuring, bløtlegging av overflatevann og underjordisk vann under søppelstabling eller deponi. Søppelvann har potensiell fare for overflatevann og undergrunnsvann. Behandlingen av søppelvann har blitt et søkelys for miljøstudier. Avfalls sigevannets karakter er høy organisk konsentrasjon, høyt metallinnhold, stort mangfold på type og volum. COD-konsentra...

The Role of Polyacrylamide Ionic Strength in Papermaking Efficiency
Polyacrylamide (PAM) is widely recognized for its critical role in improving the papermaking process, particularly as a retention agent, filter aid, and leveling agent. However, one of the most significant factors affecting its performance is its ionic strength, which can drastically influence how polyacrylamide interacts with pulp fibers and enhances the retention of fines. This interaction is no...
