Abstract: The invention is directed to systems and methods of biological and chemical treatment of wastewater comprising organic nitrogen compounds. Systems may include: an aerobic reactor, a first separation module for separating liquid and solid components of the wastewater; an oxidation module for removing organic materials from the wastewater; and a post-anoxic reactor for denitrifying at least a portion of the wastewater. Systems may include a second separation module and various feedback recycle lines between the components. Methods may include: degrading by the aerobic reactor more than 95% of organic compounds to ammonia, oxidizing by the oxidation module at least a portion of the ammonia to nitrates, and degrading by the post-anoxic reactor at least a portion of the nitrates to nitrogen gas and water. Systems and methods may reduce total organic carbon of the wastewater by more than 90%, and total nitrogen of the wastewater by more than 90%.

Abstract: Systems and methods for contracting with multiple parties, by which the multiple parties agree to a single contracting instrument, are presented. The systems generally comprise one or more computing devices connected to a data source, each of which are controlled by one or more entities interested in initiating a project. The data source has stored thereon a contracting instrument adapted for designating multiple parties. The systems also include a means for receiving the contracting instrument. The methods generally include the steps of identifying two or more contractors and identifying an owner interested in engaging the plurality of contractors to work on a project. After the contractors and owner have been identified, a single contracting instrument is prepared designating the contractors and the owner as executing parties to the single contracting instrument, which may then be executed.

Abstract: The present invention relates to a domical structure capable of enclosing the majority of operational and integrating many of the structural elements of a waste-to-energy, waste processing or other combustion facility. The domical structure according to the present invention improves the aesthetic appearance of the facility by enclosing the majority of the machinery, equipment, activities and chimney from outside view. The domical structure also reduces the cost of construction and operation by reducing the support structure and improving lighting and climate control.

The domical structure also reduces the cost of construction and operation by reducing the support structure and improving lighting and climate control. Domical structure according to the present invention also includes means for easily transferring waste and materials between different areas or processing portions of a waste-to-energy facility and for reducing downwash airflow characteristics associated with wind patterns in the wake of tall chimneys and rectangular structures.

Abstract: An apparatus for removing recyclable or other selected items from a load of mixed trash. An identifier generating a non-visual identifying signal is secured to the item and is used in conjunction with sensor devices to locate the position of the item anywhere within the load of mixed trash, to control the movement of the load along a conveyor to an extracting device, to control the movement of the extracting device and the operation of the extracting device so as to remove the selected item from the load without human intervention and under automated control.
