As you know, algae produce the highest levels of oxygen in the planet and can capture carbon dioxide. so we can use this ability to reduce carbon dioxide and produce more oxygen.
Hi, Rahman,
the highest production of oxygen is at blooming of algae! Production of oxygen is connected with growing of total biomass: look basic equation. So, will be secondary contamination. When have problem should balance (correct) ecosystem components that are out of normal state. Otherwise it can be like domestic animals in Australia - bringing new one (more and more) to correct amount previous growing wild.

Yes. Thats true but due to decreasing land for the algal growth in the ponds could reatrict this phemomena.... However it may differ region to region and availability of ponded water......
Hello Rahman,
Production of oxygen in higher quantity is possible by enhancing the growth of algae increasing their biomass. Under stressed environmental conditions like metal contamination, higher form of recalcitrant pollution, these results in the decreasing biomass of water algae that gets damaged intracellularly due to ROS production and cellular degeneration. Making clean yet nutrient rich water bodies might help algae to restore the optimum level of oxygen production. So indirectly, reducing the environmental pollution and stress, will enhance the algal biomass and so do the oxygen production.
Please note that along with multicellular algae and micr-algae, cyanobacteria is also one of the maroj part of the oxygen production and that also follows the same conditions like algae but the water nutrient content should be under control to restrict cyanobacterial bloom that might produce cyano-toxins and disturb the water eco-system.
Algae will produce oxygen in the light. If you control the pH by adding CO2, the algae will consume it with the other nutrients (which you will have to add as well).
How much biomass you need to produce the O2 you want, is a matter of calculation.
Algal cultivation increasing globally for their different uses
This is easy way to produce O2 with thir valuable materials
yes, already a lot of research is going on across the world to produce algal biomass as a potential nutritious feed stock or waste treatment, simultaneously reducing carbon loading.
Algae are a source of Oxygen and have anti-oxidant properties. This fact must be of interest to the pharma industry and an algae-based respirator is already under development (1).
Similarly, seaweeds have been shown to have antiviral properties and have been the discussion for pharmaceutical products to combat COVID-19 pandemic (2-3).

The short answer is, yes we can. In 2008, myself and my business partner, Ms. Fran Wells, designed and developed a new type of algaculture system. In the past we had raceway ponds, then came photobioreactors (PBR's). Then, came us!
These technologies were sufficient for the commercialization of algae in monoculture for the health foods markets primarily. Today, we have a new type of system we call a Biomass Engine. The apparatus contains the culture and supports growth as do the two types above but, we figured out that if designed and installed a pass-thru continuous algae harvester that was low-speed and low-shear, it should be possible to harvest from the culture at the same rate at which it grows which allows algae to be output in a stream of biomass which can continue for an indeterminate period. This is how we industrialize algae production when scaled to a maximum volume of 1.5 acre/ft. and an A/V ratio greater than 3.0, output from the system over a 24 hour period is projected to be between 1.5 and 4.0 tons per day depending on species.
The system design supports installation around the perimeter of airports to in theory, facilitate bio-jet fuel production on-site making a nearly energy independent facility. There are other applications we want to investigate. Maybe Berkeley Lab could be of assistance?
