An antimicrobial toilet includes an inner surface of a toilet bowl which includes a non-doped titanium dioxide coating. The titanium dioxide coating is photocatalytic and antimicrobial in the presence of ultraviolet (UV) light. In the absence of UV light, the inner surface of the toilet bowl is not antimicrobial. The UV light source may be actuated after the waste has exited the toilet bowl. Consequently, the waste may be used in digesters used to produce clean energy or for analysis to assess the user's health status without being exposed to the antimicrobial properties of the titanium dioxide coating. The UV light may then be actuated to disinfect the toilet bowl. The outer shell of the toilet is coated with a doped titanium dioxide. The doped titanium dioxide is photocatalytic and antimicrobial in the presence of visible light. The outer shell is antimicrobial when standard room lights are actuated.

Embodiments of the present disclosure relate to methods of treating carbon molecular sieve (CMS) membranes, and in particular CMS hollow fiber membranes, that have undergone aging-induced permeance/permeability loss. By treating aged CMS membranes in accordance with embodiments of the present disclosure, the CMS membranes may be regenerated such that the aging-induced permeance/permeability loss is reversed and the permeance/permeability of the CMS membrane is increased. In some embodiments, the permeance/permeability of the treated CMS membrane may be increased to such a degree that the permeance/permeability of the regenerated CMS membrane is at least as high as the original permeance/permeability of the CMS membrane prior to aging-induced permeance/permeability loss.

A process for producing acetic acid is disclosed in which the methyl iodide concentration is maintained in the vapor product stream formed in a flashing step. The methyl iodide concentration in the vapor product stream ranges from 24 to less than 36 wt. % methyl iodide, based on the weight of the vapor product stream. In addition, the acetaldehyde concentration is maintained within the range from 0.005 to 1 wt. % in the vapor product stream. The vapor product stream is distilled in a first column to obtain an acetic acid product stream comprising acetic acid and up to 300 wppm hydrogen iodide and/or from 0.1 to 6 wt. % methyl iodide and an overhead stream comprising methyl iodide, water and methyl acetate.
