Abstract
Bioethanol is one of the alternative sources of oil resources which received attention with biodiesel. Many countries produce bioethanol from food sources such as corn and sugarcane, but it causes food-energy conflicts and farmland problem. So it needs to focus on new biomass which is sustainable, renewable, cost-effective and do not occurred any conflicts. Algae are one of the bioma
Sewage that has been aerated
and agitated in order to promote the growth of beneficial microorganisms that break down organic matter.
The activated-sludge process is a
biological method of wastewater treat-ment that is performed by a variable and mixed community of microorganis-ms in an aerobic aquatic environment.
Purpose: to remove settleable organics and floating scum (gr
