A lens, an apparatus, and a system, as well as a method and article, may operate to receive a plurality of left eye rays through a first plurality of separating facets of a lens at an image acquisition plane, and to receive a plurality of right eye rays through a second plurality of separating facets of the lens at the image acquisition plane. Data acquired from the image plane may be used to construct a stereoscopic image, including a moving, panoramic stereoscopic image. Lenses, image capture devices, and projectors may be implemented that operate using three or more viewpoints.

Activated carbon having a low contact pH and their use in the purification of water, as well as methods for making such low contact pH activated carbon and filters and methods for purifying water are described herein. The methods for preparing such low contact pH activated carbons provides an effective and less costly means for preparing activated carbons for purification processes.

Mitigating leaching of arsenic and antimony from activated carbon

Treatment of un-wetted or low moisture activated carbon with a suitable quantity of carbon dioxide provides a material which, on contact with water, controls pH in treatment water. Use of this treated activated carbon in a water treatment system provides water having an essentially neutral pH which is immediately potable thereby eliminating the necessity to drain and dispose of any soak water. The contact pH of the treated carbon remains within the potable pH range for treatment of more than 100 bed volumes. Additionally, the modified carbon may minimize metal leaching from contaminants in the water.

Carbon pre-treatment for the stabilization of ph in water treatment

The invention aims at providing a water purifier for cultivating Chinese softshell turtles. The water purifier comprises the following components in percentage by weight: 30-40% of active carbon, 20-30% of L-ascorbic acid, 10-15% of citric acid pentahydrate, 5-8% of disodium ethylene diamine tetraacetic acid, 10-15% of malic acid and 10-15% of lauric acid. The water purifier provided by the invention can be used for solving the problem that residual feeds in a pond are acidified to reduce the pH value of the culture pond in outer pond cultivation of Chinese softshell turtles.

An activated carbon composition is disclosed, which includes an activated carbon and a carboxylic acid containing compound. The activated carbon composition is prepared by immersing an activated carbon in an aqueous solution of a carboxylic acid containing compound. The activated carbon composition is used for purifying aqueous solutions by providing a bed of the activated carbon composition and passing the aqueous solution through the bed of the activated carbon composition. The aqueous solution is passed through the bed such that the flow of the aqueous solution to be purified into the bed and the flow of purified aqueous solution from the bed has a pH differential less than ±1 pH.
