Abstract
što se procesna struja, kao šarža za taloženje, preliv iz taložnika ili izlazni tok, dovodi u kontakt i intenzivno meša sa u vodi rastvorljivim polimerom molekulska mase 1 x 104 do 3 x 107, koji je stabilan na temperaturama od 85-107В° C i efikasan u kaustičnim uslovima sa alkalnim sadržajem od 80-400 g/l (izraženo kao ekvivalent natrijumkarbonata), koji sadrži viseće hidroksamske kiselinske ili sone grupe formule (I) u kojoj je R vodonik ili katjon, u količini koja je efikasna za taloženje suspendovanih čvrstih materija iz te struje, povoljno u količini od najmanje 0,1 do najmanje 1,0 mg po litru procesne struje, pri čemu je polimer pogodno u obliku emulzije sa stepenom hidroksamacije polimera od 1 do 90 mol.%, i što se polimer upotrebljava zajedno sa anjonskim flokulantom. Prijava sadrži još 6 zavisnih zahteva.
