A composition for removing resists and etching residue from substrates containing at least one nucleophilic amine compound having oxidation and reduction potentials, at least one organic solvent, water and, optionally, a chelating agent is described. The chelating agent is preferred to be included since it provides added stability and activity to the cleaning composition so that the composition has long term effectiveness. If a chelating agent is not present, the composition, while providing for adequate stripping and cleaning upon initial use of the composition following mixing, has only short term stability. In this latter instance, the nucleophilic amine compound and organic solvent components of the composition preferably are maintained separate from each other until it is desired to use the composition. Thereafter, the components are combined. Following use of the composition, the non-used portion of the composition can be disposed of or be reactivated by the addition of a chelating agent.

A process that utilizes ammonium oxidizing bacteria (AOB) and anaerobic ammonium oxidizing (ANAMMOX) bacteria to remove ammonium from a wastewater stream. Sludge separated from the wastewater in a mainstream is processed in a sidestream that includes an anaerobic digester, a dewatering system, and a biofilm reactor. The anaerobic digester produces digested sludge that is dewatered, producing reject water that includes a relatively high ammonium concentration and a relatively low organic carbon concentration and a relatively high temperature. The reject water is treated in a sidestream deammonification biofilm reactor that includes biofilm carriers seeded with AOB and ANAMMOX bacteria that are effective to remove ammonium from the reject water. In order to remove ammonium from the wastewater in the mainstream, the AOB and ANAMMOX bacteria on the media carriers is utilized to contact the wastewater in the mainstream and to remove ammonium therefrom. Because of the conditions in the mainstream, after a period of time, the AOB and ANAMMOX bacteria does not efficiently remove ammonium. To rejuvenate the AOB and ANAMMOX bacteria on the biofilm carriers, the AOB and ANAMMOX bacteria is again contacted with the reject water in the sidestream biofilm reactor where conditions are favorable for the growth and proliferation of the AOB and ANAMMOX bacteria.
