Microalgae can be as many forms of renewable energy such as hydrogen production. Methane and biodiesel from algae, typically microalgae are grown in 2 times within 24 hours, but there are some species of algae takes just 3.5 hours. And micro algae rich in oil over 80%, depending on the species of algae are usually based on the amount of oil. 20-50%, so the algae with high oil production is required for biodiesel production due to the shortage of oil and global warming caused by the burning of fossil fuels and the increase in population. the amount of industrial waste water, increasing wastewater treatment is important and in many countries have strict control nitrogen and phosphorus.
