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.

BIOCLENS™ Interaction

Targeted Reactions

Ammonia Removal

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 Removal

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
