High area contactor

Abstract

Individual high area contactors suitable for filling a rotary biological contactor and for packing a fluid column or tower are disclosed. According to this invention each of the individual contactors include a tough abrasive-resistant outer member such as perforated substantially spherical members, or cylindrical shaped outer members such as Raschig rings. This tough outer member encloses or protects a more fragile high-area internal member or reaction support member. In a preferred embodiment such as for high temperature uses or uses where the contactor would be exposed to the ultraviolet rays of the sun, the outer member is preferably made of abrasive resistant ceramic and the high-area internal member is a ceramic sponge. In certain embodiments, the outer member can be made with a rather thin shell and still maintain its strength by the use of internal ceramic sponge shaped to provide support to the outer shell. In addition to ceramic, and for other uses, both the outer member and the high area internal member can be made of plastic like material. In other embodiments, the internal member can be made of carrageenan and resin, while in still others it may be ceramic sponge coated with a metal or other selected material. The selection of materials is dependent upon the use to be made of the contactor and the type of enzyme, reaction, etc., that is to be supported by the high-area internal members.
