Apparatus and Process for Biological Wastewater Treatment

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 from the 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.

When multiple kinds of bacterial colonies are present in a petri dish and, for example, a drug tolerance is to be measured, harvesting of mixed colonies of different types of bacteria makes it impossible to accurately determine the drug tolerance. Also, it is required to improve the throughput of a device for harvesting a bacterial colony. From images illuminated from multiple directions, isolating bacterial colonies are automatically extracted. Next, the image feature amounts are calculated from the multiple images that are illuminated from multiple directions and colonies are grouped depending on the feature amounts.
