BIOCLENS™ (Encapsulated Bacteria Lenses)
Our BIOCLENS™ technology uses bacteria encapsulated in lenses as a biocatalyst to enhance and accelerate natural biological processes which break down organic matter. The lenses contain living bacteria which is immobilised in a stable, porous PVA gel matrix. As these are stirred in a reactor, water and dissolved impurities diffuse through the lenses and come in contact with the bacteria, causing targeted reactions to occur.
Ammonium (NH4+) in the wastewater permeates into the lens to allow the ammonia oxidizing bacteria (AOB), embedded inside lens, convert the ammonium (NH4+) to nitrite (NO2–).
NH4+ + 1.5 O2 → NO2–+ 2H+ + H2O
Then the nitrite oxidizing bacteria (NOB), also embedded in the lens, then convert nitrite (NO2–) to nitrate (NO3–).
NO2–+ 0.5 O2 → NO3–
Nitrate (NO3–) in the water permeates into the lens
Nitrate reducing bacteria embedded inside the lens convert the nitrate (NO3–) to nitrite (NO2–)
Nitrite (NO2–) is then converted to nitrogen gas (N2)
Both reactions require a carbon source as an electron donor
2NO3–+ 10e– +12H+ → N2 + 6H2O
