Embodiment Construction

[0065] To facilitate an understanding of the principles of the invention, reference will now be made to the embodiments illustrated in the accompanying drawings and described in the specification written below. It is understood that no limitation of the scope of the invention is intended. It is also to be understood that the invention includes any variations and modifications to the illustrated embodiments, and includes further applications of the principles of the invention, as would normally occur to one skilled in the art.

[0066] Algae have never been successfully used for primary and secondary treatment in wastewater treatment plants because algae must have light for most of the time to grow. During the daytime hours, the algae emits oxygen as a by-product, while at night it produces carbon dioxide. If all light is cut off, it will eventually die. The wastewater is so turbid that algae are never sufficiently formed for use in the treatment plant until after the treatme...

Abstract

A self-sustaining wastewater treatment facility abates greenhouse gas abatement, captures CO2 and produces biomass to address multiple critical environmental needs. The facility includes an array of rotating media wheels that create an optimum ordered mixing of algae for sustained growth. Biomass harvested from the rotating media wheels may be provided to other processing facilities to produce, for instance, bio-fuels. Waste CO2 from the processing facility may also be returned to the treatment system for enhanced algae growth. Bacteria are provided to form a symbiotic relationship with the algae, fueled by sunlight to effectively remove toxic materials from the wastewater. The multi-functional facility may also be integrated into a regenerative facility in which the biomass obtained fromthe algal and bacterial colonies is used in a separate facility and byproducts of the operation of the separate facility are used by the multi-functional facility to fuel further algal growth.

Description

technical field [0001] The present invention provides a multifunctional device and method for the biological treatment of wastewater. This application is a continuation-in-part of, and claims priority from, application Serial No. 11 / 957,648, filed December 17, 2007, entitled "System and Method for Biological Treatment of Wastewater and Utilization of By-Products Therein," which later The application is a continuation-in-part of, and claims priority from, application Serial No. 11 / 856,175, filed September 17, 2007, which latter application claims provisional patent application No. 60 / 845,490, filed September 18, 2006 priority. Background technique [0002] Wastewater treatment has developed significantly, starting with sewage treatment in large cities. Environmental regulations require that effluents from waste water generators be treated prior to discharge into public waterways. Existing processing methods meet these regulations, but these methods generate significant GHG...
