The invention provides an improved ceramic packing element (1, 6, 8) suited to use as a bed limiter having a generally uniform cross-section in the length (l) direction with the basic shape of a bow-tie and having a plurality of through passages (5) parallel to the length dimension (L).
摘要:
Packing elements typically used in columns to enhance chemical reactions are illustrated. The packing element may be shaped as a sphere, ellipsoid or any shape of a revolution of a conic. Alternate embodiments illustrated may have faces analogous to crystal shapes. The packing elements have various shapes of drip points. The construction of the element is such that pieces can be folded thus saving assembly time and cleaning time.

摘要:
The invention relates to a carrier element for an aerobic biological water treatment system. The carrier element has a first end and a second end at a distance from each other, the maximum diameter of the first end being larger than the maximum diameter of the second end. It also has biofilm growing surface structures that extend from the first end to the second end and from inner part of the element towards periphery of the element and at least two support structures that encircle the growing surface structures at the periphery of the element and connect the growing surface structures to each other. The support structures define the outer boundary surface of the carrier element, whereby the support structures are spaced from each other so that apertures allowing access to the biofilm growing surface structures are formed between the support structures. The invention relates also to a water treatment system employing the carrier elements.
