Confidential Information.

(a)

Confidential Information is any information of a party hereto to which the other

obligation by the receiving party; or

(iv)

is required to be disclosed by law or which is reasonably required to he
disclosed in order to enforce rights under the Agreement, provided that the
receiving party shall, if reasonably possible, notify the other party of the
intended disclosure in advance, in order to allow the other party a reasonable
opportunity to seek a protective order.

United States Patent

Patent NO.: US 7,270,750 B2

Date of Patent: Sep. 18, 2007

(54) CLARIFIER RECYCLE SYSTEM DESIGN FOR USE IN WASTEWATER TREATMENT SYSTEM (75)

A recycle system for use in a waste treatment facility utilizing either
partially fluidized or combined fluidized bed filtration principles comprising
the use of discrete passage-ways to allow flow between the bottom of the
clarifier and the aeration compartment, a baffle positioned between bub-blers in
the aeration compartment and the clarifier openings, and a conduit positioned in
the clarifier to provide flow between the clarifier and the anoxic compartment
that helps prevent the formation of settled sludge pockets, allows for almost
complete evacuation of the solids during “no flow” conditions, and improves on
other inefficient conditions inherent in treatment systems using prior art
recycle designs.
