The invention encompasses liquid cleaning compositions, for example, dish washing liquids, and methods of their manufacture and use, which possess enhanced cleaning ability. A wastewater treatment apparatus may include an intake unit, one or more gravity separation air flotation units, and a discharge unit. Based at least on the first plurality of images, a long TET, a short TET, and a TET sequence that includes the long TET and the short TET may be determined. The pump is supported by elastomeric tubular members from its ports. The system includes a turntable that positions the green body for the printing operation, and then rotates the green body to position the printed mark first in front of a dryer, and then in front of the optical reader to determine the quality of the mark.
