Lagoon & Pond Aeration

Head-to-head vs. blowers

In order to demonstrate the high oxygen transfer capability of the integrated fine-bubble aeration system, we ran a five-month head-to-head project with compressors vs. blowers.  

One project was equipped with a compressor and fine-bubble aeration system with maximum air flow capability of 50 LPM. The other was equipped with a blower and coarse-bubble aeration system, capable of maximum airflow of 90 LPM.

Our results showed that the compressor system was capable of reducing influent ammonia concentrations and COD to the same level as the blower system, despite delivering about 45% less air.

Low-energy compressors beat blowers for efficiency and cost

Aeration is costly, so when we designed Bishop BioCord reactors, we focused on achieving a high level of nutrient reduction using the least possible amount of energy.

Instead of using blowers and coarse bubble aeration for BioCord Reactors, we perfected an aeration system that uses fine bubble diffusers and low-energy compressors.

Our compressor/fine bubble aeration system can achieve similar levels of dissolved oxygen in the reactor tank to blowers, even though it delivers almost 50% less air. Not only does that translate to lower initial capital costs (compressors cost less than blowers) but it also contributes to major operational savings in energy costs and maintenance.
