  • Wastewater Treatment Bed, Facility and Method
    Publication number: 20140197099
    Abstract: A facility and a method for treating high strength wastewater include a plurality of beds having layers of granular and textile material through which the wastewater flows for reduction of BOD and COD. The wastewater is conducted to and from the beds using piping networks. Distribution conduits and drain conduits are arranged within the bed. Wastewater flow is controlled by valves remotely actuated via a control system.

  • S-triazine degrading bacteria
    Patent number: 5429949
    Abstract: A pure bacterial culture, designated herein as M91-3, has been isolated which rapidly degrades certain s-triazines, particularly halogenated s-triazines. The M91-3 degrades s-triazines, particularly atrazine, beyond the point of ring cleavage, leading to complete mineralization of the atrazine. The ability of M91-3 to completely degrade atrazine appears to be unique among bacteria. The M91-3 is capable of degrading s-triazine in solution and in presence of soil or sediment. The invention also relates to a method for degrading s-triazines, particularly atrazine.
