How BioGill Technology Works
BioGill manufactures above ground, attached growth, bioreactors that deliver compact, affordable wastewater treatment solutions. Key to BioGill performance efficiency is the growth of healthy biomass on the patented nano ceramic media, known as “gills”.
Our technology relies on the availability of suitable nutrient mix in the wastewater and the availability of oxygen transfer to the gill structure. With these in place, BioGill units maximize the load of treating biology, which in turn consume the organic nutrients found in the waste stream. The gill structure means an above ground, non-submerged culture can attach to the gills as a biofilm.
The BioGill bioreactor is a secondary treatment process that removes soluble nutrients (BOD/COD) from the wastewater. The process also allows for a reduction in: Fat, Oil and Grease (FOG); Turbidity; Odor; and Suspended Solids through secondary functions.
Effective Gill Technology for Wastewater Treatment
Arranged in suspended vertical loops, each gill is folded over a support, creating two distinct sides: one in contact with the wastewater and the other in contact with the air. The liquid is dispersed over the top of the bioreactor and moves down between the gills. The biomass growing on the gills is supplied oxygen from the atmosphere via the air side and soluble nutrients from the water side.
Cleverly designed air spacers ensure ample airflow from the atmosphere reaches the microorganisms, which grow on both sides of the gills. With the increased oxygen transfer and high surface area to volume ratio, BioGill units grow a healthy, active biomass that can achieve biomass density as high as 50,000 mg/L or better.
As the biofilm develops and thickens, the outer layer becomes substrate limited and eventually dies and sloughs off. The bioreactor will naturally develop sufficient biomass to support the nutrient conditions of the system. This efficient process reduces sludge yield and the large particles readily settle in the treatment tank, reducing operator involvement while ensuring efficient nutrient removal.
The configuration of the bioreactor decouples the need to aerate the water, as required in conventional activated sludge systems. This feature reduces the energy footprint of the technology by up to 80%.
