Description

Осадок после фильтрации с содержанием 98% NaF (пересчет на сухой осадок) и влажностью до 30% промывают небольшим количеством раствора из абсорбера, что увеличивает содержание NaF в осадке до 99%.The precipitate after filtration with a content of 98% NaF (recalculated to dry sediment) and humidity up to 30% is washed with a small amount of solution from the absorber, which increases the NaF content in the sediment to 99%.
