Dear Rakshit P.

Interesting discussion,

The blue green algae are not algae, but a form of bacteria that is an unusual green color. Also called cyanobacteria, blue green algae grow in both salt and fresh water, especially quiet lakes and ponds where they give the water a dark green color. Microalgae have demonstrated great potential as an alternative to advanced biological nutrient removal because it can reduce energy costs. The process does not require the addition of chemicals, it is simplified by not needing numerous tanks for operations and internal recycling, it can simultaneously deliver nutrient removal and reduce the CO2 footprint and it generates oxygenated treated water to the receiving bodies. Additionally microalgae sludge has ample post-application potential; it could be a source of high-value products  for use as biofuels and bioproducts. Blue green algae, including a type called spirulina, contain valuable nutrients and could also provide additional health benefits The history of the commercial use of algal cultures spans about 75 years with application to wastewater treatment and mass production of different strains such as  Chlorella  and Dunaliella . These are due to the understanding of the biologists in these nations for the biology and ecology of large-scale algal cultures, as well as in the engineering of large-scale culture systems and algal harvesting methods, all of which are important to the design and operation of high rate algal cultures to produce high-value products, such as Pharmaceuticals and genetically engineered products. Algal-based wastewater treatment systems use photosynthetic energy to drive nutrient removal, recent studies have sought to build on the early efforts to develop improved algal systems for urban wastewater treatment. The premise of this approach is that, mixed algal/bacterial systems can simultaneously reduce BOD, N, and P in urban wastewaters. The energy-rich biomass produced would then serve as feedstock for producing gaseous or liquid biofuels. This approach incorporates much of the internal energy of the wastewater into the biomass as well as solar energy captured via photosynthesis. The proposes a potentially energy-positive WWTP process specifically intended for warm-to-hot, arid regions where water is precious, such as New Mexico. Presents nutrient removal ability of an algal extremophile, Galdieria sulphuraria, with a broad genetic capacity for organic carbon utilization. The theoretical rationale of this proposal is that, the algal systems can produce nearly double the biomass per unit nutrient intake than bacterial systems and can generate nearly 20% more net energy.
