Porous Substrate Bioreactor

Basics

• Often Abbreviated as PSBR or PSB
• May need a "Phot-" bit to differentiate between non-photobioreactors?
• Seems to be the Hydroponics / Aeroponics of PBRs
• Uses a porous substrate (often sintered something, although mesh screens/felt, and maybe even expanded metal *should* work?) to grow a biofilm of algae
• Either uses continuous flow, or pulsed (like tidal (forget the word) ) hydroponics
• Saves water (especially if evaporated water is recovered)
• More exposure of algae to circulated gas thus oxygen to co2 concentration can be optimized
• Can have more light expose than some other methods
• Works especially with Product Excreting Algae <- may need better name
• Does it Require Periodic "Scraping" ?
