Patent number: 6426004Abstract: A method and a reactor system for continuous waste water treatment are disclosed. The method involves the steps of continuously flowing an influent into a treatment basin and continuously flowing an effluent out of the treatment basin into a clarifier. The influent is continuously and completely mixed in the treatment basin. In an additional step, oxygen is introduced into the basin for a first predetermined time period. The introduction of oxygen into the basin is then stopped for a second predetermined time period and then the steps of introducing and stopping the oxygen are repeated. The reactor system includes a treatment basin having an inlet for continuously receiving an influent stream, an outlet for continuously discharging an effluent stream, and contains a mixed liquor. At least one mixer completely and homogeneously mixes the mixed liquor.Type: GrantFiled: September 14, 2000Date of Patent: July 30, 2002Assignee: BASF CorporationInventors: William C.

Publication number: 20020098356Abstract: Dyeable and dyed filaments have a core and a sheath which entirely surrounds the core. The core is formed of a core polymer which is susceptible to dyeing by a dye bath chemical, while the sheath is formed of a sheath polymer which is resistant to dyeing by the dye bath chemical. When the filament is brought into contact with a dye bath containing the dye chemical, the dye chemical in the dye bath will physically diffuse or migrate through the sheath polymer to cause the core polymer to be dyed a color of the dye bath chemical, while the sheath polymer is substantially undyed thereby.Type: ApplicationFiled: January 16, 2002Publication date: July 25, 2002Applicant: BASF CorporationInventors: Matthew B.
