Air scrubbing explained

Legislation will require that emissions from animal production are managed to reduce environmental impact, by reducing Ammonia, Odour and Fine dust. Energy waste from the process is harnessed and reintroduced to provide an optimal environment for the animals. As a result of this, the animals should experience better welfare and health

As air leaves the stall it enters the ‘air scrubber’ where it passes through a water curtain and is washed before exiting to the environment outside. As clean air. The wash water continues to circulate through the system, being deposited in a pit before being pumped for recirculation.  To main good water quality for maximum performance, a connectivity sensor measures the nitrogen in the water and when too high instructs a valve to send the concentrate to a waste tank. This means the system can continue to run and requires minimal maintenance. The remaining water continues to circulate being heated by the washed air. This heat energy can be later used to condition air for optimal climate back in the stall.  

There are three types available:

  • Biological system uses micro-organisms  in the wash water to reduce ammonia and odour from the stalls. This results in an ammonia reduction of 85%, 45% odour reduction and up to 75% dust reduction.
  • Chemical system reduces ammonia and odour levels by adding acid to the wash water, which causes the PH to increase. This results in an ammonia reduction of 70 to 95% and up to 30%...

'As an advocate for a future world of Digital animal farming, I continue to search new approaches, namely how to address the challenge that Information technology brings to farmers. My belief, we’ll see an evolution to a two tiered approach, where traditional farming meets centralized data analysis and farm optimization. I continue to evangelize this approach as a way, to not only drive more value from farm investment, but also resolve some of the broader challenges the supply chain faces. As we continue to intensify, we should try to do it in the most responsible way possible.
