System and method for biological wastewater treatment and for using the byproduct thereof
First Claim
1. A process for wastewater treatment comprising:
- biologically treating wastewater in a first treatment facility using algae to produce a substantially clean effluent and a byproduct of biosolids;
using photosynthesis and nutrients from the wastewater in the first treatment facility to produce algae growth and thereby increase the biosolids produced by the facility;
extracting the biosolids including algae from the first treatment facility;
providing the biosolids to a separate facility for processing the biosolids and producing waste CO2; and
providing the waste CO2 to the first treatment facility to support the algae growth.

Abstract
A wastewater treatment system and process biologically treats wastewater to produce substantially clean water effluent and byproducts. The treatment system includes an array of media wheels that rotate into and out of exposure to sunlight for sustained algae growth. One byproduct is algae removed from the rotating media wheels, which may be provided to other processing facilities to produce, for instance, bio-diesel fuel. Waste CO2 from the processing facility may also be returned to the treatment system for enhanced algae growth. Bacteria is provided to form a symbiotic relationship with the algae, fueled by sunlight to effectively remove toxic materials from the wastewater. Large scale facilities may integrate the treatment systems in a regenerative cycle in which the biomass obtained from the algal colonies is used in a separate facility and byproducts of the operation of the separate facility are used by the treatment system to fuel further algal growth.
