Air scrubber systems explained
An air scrubber system is the ideal solution to reducing harmful emissions. Intensive livestock farming is legally obliged to descrease the emission of ammonia, odour and particulate matter in order to reduce the impact on the environment. Therefore, Inno+ has developed a system to tackle this.
Working of the air scrubber systems
The airscrubbers work rather simple, though effective:
- The ventilation air comes in contact with water.
- The washing water is continuously pumped around, together with the ventilation air.
- This washing water absorbs dust, odour and ammonia particles.
- The outgoing air cleane thoroughly.
For maximum removal of dust, odour and ammonia, it is necessary to continuously control the wash water quality. The two most important parameters that are controlled and regulated are the pH and the conductivity of the wash water. A constantly regulated pH is necessary to achieve optimum removal of ammonia and odour molecules. The conductivity control is necessary to control the desired maximum nitrogen content in the drain water.
Watch the video below to get a better understanding of how the best air scrubber works.
Different types of commercial air scrubber systems
Inno+ has three different types of advanced air scrubbers available:
- Biological systems : these use microorganisms in the wash water to reduce ammonia and odour from the stables. This leads to a minimum of 85% ammonia reduction, 45% odour reduction and 80 % fine dust reduction.
Download our whitepapers about biological Air Scrubbing here! - Chemical systems : they reduce ammonia and odour by adding sulphuric acid to the wash water, whereby the pH drops, and ammonia is taken up in the water . This leads to an ammonia reduction of 70 to 95%, an odour reduction of 30% to 40% and a particulate matter reduction of 35%.

A combi system can include both a biological or chemical system combined with a water washer and or biological filter. This leads to an ammonia reduction of 70 to 85%, an odour reduction of 30 to 75% and an average fine dust reduction of 80%.
Systems for manure treatment
Next to our systems for use in pig or poultry stables, we also have air washers used for manure treatment. These prefabricated chemical air scrubbers are designed to be used after the Big Dutchman CompoLiner manure treatment system.
When connected to the CompoLiner, the air eventually enters the scrubber part from the bottom. After being intensely rinsed in the horizontal washing bed, the process water is dosed with acid and recirculated until it reaches a certain pollution level. At the end, clean water is added to the process water of the air scrubber.
All the measurements, valves and controls are fully automated for easy operation. The wastewater can be used as a liquid fertilizer as it contains ammonium sulphate.
Combining airscrubbers with heat recovery
Energy that is lost during the washing process can be recovered and reintroduced into the production process to provide the animals with an optimal climate environment. This means the animals experience more well-being and better health.
We combined the best airscrubbers with heat recovery for ‘Kuijpers Kip’, a poultry house located in The Netherlands. Watch the video below for more details.
A suitable solution for a pig farmer in France
Together with Big Dutchman, a biological air scrubber was provided to David Grone, a pig farmer located in Prat, in the region of central Brittany, France. The plan was to build a new building suitable for 3000 piglets. Big Dutchman was asked to provide the building with a complete farm ventilation system.
During the first phase of the project, air washers weren’t included in the building and local authorities weren’t pleased about this, because of the harmful emissions and smells that would hinder the environment and local neighbours. The Porcus air scrubber system was chosen to counter these negative effects. The system used for this project was made and tested at the Inno+ factory in the Netherlands and then shipped as a single unit for installation.
Pig Farmer David Grone was very pleased with the result, and stated: We are very pleased with our decision to invest in this type of system and would recommend it to anyone needing to install air scrubbing
What are the advantages?
The systems of Inno+ have several advantages that might be interesting for you.
- Our airscrubbers have a large filter surface. This means a low air resistance and the energy consumption of the fans is considerably less.
- A unique pump technology for the wash water guarantees continuous watering of the package in the air scrubber, so that they are continuously rinsed clean. This pump technology, combined with unique pre-filters, also guarantees lower energy costs, because the hydraulic dimensions of the pipes and nozzles mean less water resistance.
The advanced air scrubbers are easy to maintain and control.
- Two sensors that measure the pH value make it is possible to control the supply of sulphuric acid and the activity of bacteria. Furthermore, a conductivity sensor measures the nitrogen concentration in the process water. Both are indicators of water quality and crucial for optimum performance.
- For the necessary maintenance all components are easy to reach and to clean. There are also data management systems , both locally and via the Internet, with which the user can monitor the washing process . This makes it possible to intervene quickly if necessary.

A new generation of airscrubbing
Reducing harmful emissions is still an important topic for livestock farmers. Because of this, we are continuously looking for the best suitable solution to tackle this problem. In the past 15 years, we have realized numerous projects for reducing harmful emissions in livestock houses, and with great success. However, the experience we obtained during these 15 years, as well as collaborating with several pig farmers, we have successfully developed two brand new air scrubbers.
These new systems are a biological and chemical air scrubbers that reduce harmful emissions more effective than ever before. For example, our new chemical system can reduce ammonia by 90%.
Data registration of our airscrubbers
The real-time data recording system can be continuously monitored from a central location by our technical team to ensure the optimum performance that was agreed upon. This allows our customers to respond to changes in their business and to repair any problems that arise, so that they can achieve their emission reduction targets continuously.

Specific to Pollo
- The stable air is rinsed with water before it reaches the air scrubber.
- Part of the dust is caught at this point in the process.
General for dust
- Spray nozzles distribute washing water over the washing package.
- Stable air passes through the washing package and comes into contact with the washing water.
- Here the remaining dust (and ammonia, odour) is intercepted.
Other
- An air scrubber is built up of individual sections of 2,4 m width and 2,4 – 8,4m depth in steps of 0,6m
- The air scrubber comes in the range of 1, 2, 3, X sections
- A 6 sections scrubber with a depth of 6,6m has a surface of 6 x 2.4 m = 14,4 m width x 6,6 m depth is 95,04 m2
- The washing package (packing material) is 0,6 m thick
Minimum surface calculations based on the following
- For Broilers 2741 m3/m2xh.
- For Layers 2000 m3/m2xh.
Eg. At an exhaust air volume flow of, for example, 300.000 m3/h we have the following results:
- For Broilers a minimum surface of 109,4 m2
- For Layers a minimum surface of 150 m2
Skids
A skid is termed as a ‚‘engineered frame for equipment‘, in this case the technology that drive the air washer.
- The technical room is equipped with a prefab skid.
- All technical parts are attached and tested on this skid to make on-site assembly as quick and easy as possible
- The basic skid can be extended by up to 4 pumps
Module
A Module is a complete prefab air scrubber in a plastic housing
- The technical room is on the side of the ‚Master‘ module
- All technical parts are mounted in this room and tested to make on-site placement as quick and easy as possible
- Modules are built up with sections of 2,4 m width x 2,1 m depth
- A Master module can be expanded with up to 2 extension modules
- A range of 1 to 13 sections is available
- Piping between modules is included, but needs to be installed on site
Due to air capacities it is recommended to use built-in for poultry instead of modules, due to practicalities on sizing.
