does the limited nutrient on the secondary treated effluent has an impact on microalgal biomass productivity and is this directly linked to biodiesel production? could it be feasible for a commercial scale? all of your answers/ suggestions would be appreciated.
1) The proportion of available N, P and K do not necessarily meet the needs of the algae
2) Important microelements may be missing from the wastewater
3) The penetration of light in an algal suspension is only a few cm-s, so the configuration of the photoreactor is quite a challange
4) Algal strains selected for high lipid production are rather sensitive to microbial infection
5) You need a cheap method to harvest the algae, and to extract the lipids from the algae, otherwise the price of the biodiesel will not be competitive.
Dear Researcher Dr. E Y B,
Micro algae needs a fair less contamination type of water.
It's best to have an initial process
of phytoR using Reed type of sp
to fix majority of salts in rhizomes
n roots of plants in process.
When less polluted water is led in
the final stage of phytoR, it works
Well. Float beds are used for ease
of replacing the plants n roots in
Process.
As water is being used for raw plants sp intended to be used for making bio-diesel, the plants and roots accumulations can be fed to open hearth flame applied furnace in use for bio-diesel's raw matter heating to vaporisation point of bio-disel vapours prior condensation to bio-diesel as distillate - pre final produce of raw fuel
This distillate is further processed if needed for more purity Etc.
Well wishes

there is also not enough light to have algae growing. You do not want to built treatment plants with more than 30 h retention time. so what to do at night?
