BIOCLENS® (Lens Encapsulated Bacteria)

BIOCLENS®

Lens Encapsulated Bacteria

Our BIOCLENS® technology uses encapsulated bacteria in a lens shaped carrier to provide intensified ammonia and nitrate removal to very low levels.

Desalination of water

Cost Effective Ammonia and Nitrate Removal

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. The specific bacteria required for nitrification or denitrification can be encapsulated in the lens, creating intensified activity. The encapsulation protects bacteria in saline environments and from high concentration of ammonia or nitrate in the feed (above 1,000ppm).

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
