Photobioreactors and open ponds are two of the most common ways to do algae biomass cultivation. The high concentration of algae through a controlled environment is achieved with the use of photobioreactors . It is a closed system, which provides all the right conditions to promote substantial amount of algae for use as bio fuel. It also promotes adequate supply of carbon dioxide, water, light exposure, accurate temperature, culture density, acidity or pH levels, gas supply rate and other essential components for algae cultivation.

The modern design and construction of genetically modified algae biomass is a sure step towards and greener and more sustainable production process. A good Photobioreactors can control and measure the correct parameters for a conducive environment for algae growth. It also investigates, analyzes and optimises the process.

Photobioreactors are most commonly computer controlled by well qualified professionals and experts. It automatically regulates inlet gas mixture and online analysis of the exhaust gas by a chromatograph. By utilizing this system, it is easier and more accurately possible to investigate and optimize hydrogen production process of the wild-type and genetically engineered cyanobacteria and sulphur derived green algae biomass.

Here is the simplified process of algae growth through Photobioreactors:

1. The flow goes to the diaphragm pump from the feeding vessel. It moderates the flow of the algae into the tube. A CO2 inlet valve is built into the pumps.

2. All the right environmental parameters needed for the growth of algae is done through the photobioreactor itself. It controls even the amount of light that is needed. It is made of acrylic. The design allows light and dark intervals, which is ideal for the growth or algae.

3. In order to have a good supply of algae, the photobioreactor needs to be clean consistently without disrupting the process. It contains its own cleaning system which does the job.

4. Before is passes to the feeding vessel, the algae should already have gone through the photobioreactor. As it flows steadily into the hoses an oxygen sensor will assess the amount of oxygen the algae contains, which it got from the whole process. The gas is then released in the vessel itself.

5. At the same time, a built-in optical cell density sensor is determining the rate the algae is harvesting.

6. The algae pass through a connected filtering system, which signals its readiness for harvesting. A filter, then collects it and is then gathered for processing. Any remaining algae passes back to the feeding vessel again.

7. The whole process then is repeated from the start.

Photobioreactors are a great way to go green by harnessing the natural power of the algae biomass. It helps lessen toxic emissions and will promote earth healing while giving us reliable and sustainable source of energy.
