Particulates in air and prevention in ending up into spirulina
posted 3 months ago
Small particles in air are a growing concern.
As we grow spirulina and aerate it, the particles will also end into the algae.
We should have first a waterfilter, which will take away dust and particles from the air and after that, the air would be directed to the the spirulina.
If the water is in fact lye, made from wood ash: it will also serve as filter from microbe contamination, as most of them from the air, will stick into water and die couse of the high pH in lye: 12-13.
Then you change the lye from time to time. It is not poisonous to earth, if you just spread it evenly in a big area: in fact, as we have acid rain, it will rise up the pH of the soil, making a good change. Just remember to dilute enough.
So first the air is aerated through lye, and then aerated to the algae.
Algae is very good to grow inside home, so the air is cleaner. But if you intend to eat the algae, you should use this kind of simple system.
I will (when I got money for new aquarium pump) make this filter and post pictures also. It would be good to do also experiment, does it affect to the growth of algae in positive way.
