Research progress and application of photobioreactor in wastewater treatment

The first photobioreactors were born in the 1950s, and based on microalgae have potential applications pharmaceutical industry, food feed production, environmental engineering, wastewater treatment, renewable energy. Photobioreactors used pollutant treatment for carbon dioxide sequestration 1953 at Carnegie Institute Washington. use stable efficient algae cultivation technology to create an artificial environment that provides all necessary conditions growth such as (light, temperature, nutrients), these can be controlled monitored, especially cultivation, It is convenient rapid, controllable of microalgae. Currently, there are many types microalgae-based terms configuration, fabrication materials, operating modes. optimize biomass improve efficiency removal, reduce cost space advantage. most common structures flat, columnar tubular, followed by hoses hybrid photobioreactors, taking their flexibility efficacy a higher level. Each photobioreactor type has its own advantages disadvantages operation, removal efficiency, level upgrade.
