Abstract: A filter element is provided for being removably arranged in a filter housing, the filter element including a filter material body. The filter element is adapted to assume a first state, in which it has a substantially flat shape, and a second state, in which it has such a curved shape, such that opposite outer peripheral sides of the filter element are directed towards each other and in which it is adapted for a filtering operation. The filter element is adapted to be locked in the second state when arranged in the filter housing. A filter system is also provided including a filter element and an anchoring device adapted to be arranged between the opposite outer peripheral sides of the filter element when it is curved to the second state.

The sealing ring lip is designed to seal relative to a housing component of a receiving filter housing. A support ring is arranged at the end face of the filter medium body at a radial distance to the sealing ring lip in a radial direction relative to the center axis. The support ring is supported in the radial direction at the support frame and is formed as one piece together with the support frame.

Abstract: Internally activated energy distribution guides for use in clear to turbid liquids or air have been developed. An external energy source is transferred to a matrix or single fiber of a side emitting fiber or guide to internally activate a promoter or catalyst on the exterior of the fiber or guide to thereby dissociate target molecules passing by or along the fiber's or guide's surface by a Precise Energy Separation (“PES”) method. A number of different designs can be used, for example, in a mesh, louver system, or box. The method maximizes the interaction between the target molecules and the surface of the side emitting—internally activated distribution network. In a preferred embodiment, u-shaped fiber optics containing catalyst are positioned within tube through which the turbid liquid or air is passed, so that maximum cleavage of targeted bonds is obtained.

Abstract: A process for treating an ionic liquid containing waste stream is described. If there is a liquid waste stream, the liquid waste stream is introduced into a liquid treatment zone. The ionic liquid in the liquid waste stream is neutralized. The concentration of the ionic liquid in the liquid waste stream is determined, and the allowed concentration of the ionic liquid in the liquid waste stream is determined. The concentration of the ionic liquid in the neutralized liquid waste stream is reduced to the allowed concentration, and the liquid waste stream having the allowed concentration is released. If there is a vapor waste stream, the vapor waste stream is introduced into a vapor treatment zone. The vapor waste stream is treated to form a treated vapor waste stream, and the treated vapor waste stream is released to a plant vapor treatment zone.
