摘要：

This paper presents the results obtained in laboratory in conditions uses a retention system with two cationic components (polyetylenimine-PEI and polyacrylamide-PAA) for fibers suspensions (hardwood and softwood) with 30% CaCO3 and mechanical pulp. The results show in all situations the high grows of the dewatering and the variable grows of the retention in function by fiber type used.
