摘要:
A coagulant which is the reaction product of a trivalent metal salt, excluding chromium salts, an acid phosphorous compound and an aluminum hydroxy chloride, and a process for preparing such coagulant. This coagulant may be effectively used to remove suspended solids and various impurities in most water treatment applications.

A coagulant which is the reaction product of a trivalent metal salt (eg., FeCl3), excluding chromium salts, an acid phosphorous compound and an aluminum hydroxy chloride, and a process for preparing such coagulant. This coagulant may be effectively used to remove suspended solids and various impurities in most water treatment applications.
摘要:
A distinctive absorbent article includes a backsheet layer, and an absorbent structure superposed on the backsheet layer. The absorbent structure includes particles of high absorbency material, and a liquid permeable topsheet layer is superposed on the absorbent structure to sandwich the absorbent structure between the topsheet layer and the backsheet layer. A fibrous face sheet layer is incorporated in the article for restraining a movement of the high absorbency material from selected regions of the absorbent structure. The face sheet layer has a Frazier Porosity value of at least about 150 cubic feet per minute per square foot of surface area (cfm/ft.sup.2), and has not more than about 100 pores (per 31.37 cm.sup.2 of surface area) with a pore size greater than about 300 micrometers.
