Method for mass rearing of rotifers of the genus Lecane, potentially used in reducing the swelling of activated sludge in sewage treatment plants

摘要

The object of the invention is the mass rearing of Lecane-type skates, potentially used to limit the swelling of the active sludge in sewage treatment plants, used outside the active sludge chambers, consisting of the rearing on scales (1),in liquid medium and when fed with an artificial medium. The cups (1) are set in vertical modules, preferably after ten cups, each module contains a flat base and a cover. Shawls (1) have a ribbed bottom (2) with openings (5) secured tightly with sections of vertical tubes (6) in such a way as to prevent the medium from mixing between the shawls (1),air exchangers instead.
