Methods And Compositions For Waste Treatment Of Organic Strippers Containing Metals
US Patent:
5422032, Jun 6, 1995
Filed:
Jan 18, 1994
Appl. No.:
8/183475
Inventors:
James A. Brown - Layton UT
Assignee:
Viktron Limited Partnership - Carol Stream IL
International Classification:
C02F 152, C02F 162
US Classification:
252175
Abstract:
Compositions for use in the treatment of complex waste liquids are disclosed. The complex waste liquids may include organics, organic polymers, and heavy metals. The composition is a solution comprising, in relative percentages, from about 2 moles to about 3 moles Me. sup. III, from about 1 mole to about 3 moles Me. sup. II, and from about 4 moles to about 5 moles monovalent or divalent anionic groups. In such a composition Me. sup. III is selected from the group consisting of Fe. sup. +3 and Al. sup. +3 ; whereas Me. sup. II is selected from the group consisting of Mg. sup. +2 and Ca. sup. +2. The anionic groups are generally selected from the group consisting of Cl. sup. -, NO. sub. 3. sup. -, and SO. sub. 4. sup. 2-.

US Patent:
5308502, May 3, 1994
Filed:
Dec 17, 1992
Appl. No.:
7/992119
Inventors:
James A. Brown - Layton UT
Assignee:
Tandy Coporation - Fort Worth TX
International Classification:
C02F 152, C02F 162
US Classification:
210724
Abstract:
A method for treating liquid wastes containing photoresist polymers and heavy metals is disclosed. The method includes adding to the liquid wastes an aqueous solution of water soluble FE. sup. +3 and Al. sup. +3 salts at a pH in the range of from about 0. 1 to 1. 0, and a water soluble salt of Mg. sup. +2 or Ca. sup. +2. The ratio of the amount of the Fe. sup. +3 and Al. sup. +3 to the amount of the Mg. sup. +2 or Ca. sup. +2 is in the range of from 2 to 3 moles to 1 to 3 moles. A precipitate containing the heavy metals and photoresist polymers is formed.
