Szukana fraza: [Abstract = "Process was carried out at optimum process parameters\: rapid\-mixing \- 3 min at the rotational speed of 200 rpm, slow mixing \- 10 min at 30 rpm, sedimentation \- 60 min. The removal effectiveness was dependant on coagulant type and its composition. Better results in the removal of 5\-and 6\-ring PAHs were obtained after application of FLOKOR 105V \(lower aluminum content\) than after using PAX XL 19H."]
