Air scrubbers for livestock farming:
Good level of emission reduction through proven technology
It is a legal requirement in intensive livestock farming to reduce emissions of ammonia, odour and particulates in order to reduce the impact on the environment.
An air scrubber is the tool to help meet this requirement. The air that leaves the house goes outside through an air scrubber. During this journey, the air is cleaned so that the outgoing air contains a minimum amount of ammonia, odour and particulate matter.
Thanks to our certification, Inno+ can guarantee that the technology used results in a reduction of ammonia up to 90%, dust by up to 70% and of odour by up to 75%.
Furthermore our air scrubbers are plug and play. Thanks to its dimensions we can easily deliver the units anywhere in the world and your local installer can install the it within one day.
Operation of the air scrubber
Our scrubbers works quite simply, but effective:
- The ventilation air comes into contact with the water in the scrubber.
- The washing water is continuously pumped around.
- This washing water absorbs dust, odour and ammonia particles.
- The outgoing ventilation air is well cleaned.
It is necessary to continuously control the quality of the washing water for maximum removal of dust, odour and ammonia. The two most important parameters that are monitored and regulated are the pH and the conductivity of the washing water. A constantly controlled pH is necessary to realise an optimal removal of ammonia and odour molecules. The regulation of the conductivity is necessary to regulate the desired maximum nitrogen content in the washing water. In addition, several other processes are controlled and measured to ensure optimal performance of the air washer.
Watch the video for an idea of how the scrubber works, in combination with climate conditioning. The scrubber is used for various markets, such as pig, cattle and poultry farming and manure treatment systems.
Unique air scrubber system + Triple EEE yields high cost savings
The Triple EEE concept is a sustainable system for heat recovery. The purpose of the Triple EEE concept is to recover energy from the process water of the scrubber. This energy is then used to pre-heat the incoming air in the winter period. Another goal of the Triple EEE system is to improve the air quality in the house. Because more energy is brought into the house, more ventilation can take place and the relative air humidity, CO2 concentration and other harmful substances are reduced.
With the Triple EEE concept, with 1 kW of electrical energy for the installation, you can recover up to 77 kW of thermal energy from stall air for preheating the incoming ventilation air. The Triple EEE concept realises a reduction in heating costs up to 60%. In combination with a heat pump for post-heating, this results in a total cost saving up to 87%.
Different types of air scrubbers
There are two different types available:
Biological solutions
Our biological systems use micro-organisms in the scrubber water to reduce ammonia and odour from the houses. This leads to maximum 85% ammonia reduction, 75% odour reduction and 70% particulate matter reduction.
The advantages of this system:
- Standard and customised solutions: This type of scrubber is suitable for both new and existing situations. Custom and standard solutions are therefore possible.
- Measurement of important parameters: acidity, conductivity of the washing water, electrical consumption, amount of discharge water and pressure difference of the scrubber are measured automatically.
Chemical solutions
These reduce ammonia and odour by adding sulphuric acid to the wash water, which lowers the pH and absorbs the ammonia. This leads to an ammonia reduction of 70 to 95%, an odour reduction of 30% to 40% and a fine dust reduction up to 87%.
The advantages of this system are
- Less resistance: a horizontal version of the chemical scrubber has less pollution and lower resistance. As a result, there are fewer maintenance costs and the energy consumption is considerably lower.
- Heat recovery possible: the chemical air scrubber can be equipped with a heat recovery system. The free animal heat from the water can be used to heat, for example, ingoing air, floors, liquid feed, farm buildings or your home.
- Datalogging: The most important parameters such as acidity, conductivity of the wash water, electrical consumption, amount of waste water and pressure difference of the system are all measured. This valuable information can be viewed via smartphone, tablet, laptop or PC.
The advantages of the Inno+ systems
Our systems have several advantages that might be interesting for you.
- Our scrubbers have a large filter surface. This means a low air resistance, which reduces the energy consumption of the fans considerably. And still make the right amount of air filtration possible.
- A unique pump technology for the washing water guarantees continuous sprinkling of the washing packages in the air cleaner, so they are continuously rinsed clean. This pump technology, combined with unique pre-filters, also guarantees lower energy costs, as the hydraulic dimensions of the pipes and nozzles mean less resistance for the water.
The scrubbers are highly efficient and easy to maintain and regulate.
- Via sensors measuring the pH value, it is possible to regulate the supply of sulphuric acid and/or sodium hydroxide (lye). Furthermore, a conductivity sensor measures the nitrogen concentration in the process water. Both are indicators of water quality and crucial for optimal performance.
- For necessary maintenance, all components are easy to access and clean. There are also management systems, both local and via the Internet, that allow the user to monitor the washing process. This makes it possible to intervene quickly if necessary.
Data registration
The real-time data registration system can be continuously monitored from a central location by our technical team to ensure the optimal performance that was agreed upon. This enables our clients to react to changes at their company and repair any problems that occur, so that they can continuously meet their emission reduction targets.
Data registration also creates the possibility to add the data of the air scrubber to the other data collected in the farm. This makes our products a valuable tool to meet your smart farming goals.
Specifications of the Inno+ air scrubbers
General
- Nozzles distribute wash water over the filter package.
- Stable air passes through the wash package and comes in contact with the wash water.
- Here the remaining dust (and ammonia, odour) is intercepted.
Other
Modular construction
- An air scrubber is constructed with individual segments of 2,4 m wide and 2,4 – 8,4 m deep in 0,6 m increments.
- The air scrubber consists of a series of 1, 2, 3, X segments
- A scrubber with six segments at a depth of 6,6 m has a surface of 6 x 2,4 m = 14,4 m wide x 6,6 m deep or 95,04 m2
- The wash package (package material) is 0.6 m thick
Minimum area calculations based on the following
- For broilers 2741 m3/m2xh.
- For laying hens 2000 m3/m2xh.
Example – With a volume flow of outgoing air of, for example, 300,000 m3/h the results are as follows:
- For broilers an area of at least 109,4 m2
- For laying hens an area of at least 150 m2
Skids
A skid is a specially built frame for equipment, in this case for the technology to drive the air scrubber.
- The technical room is equipped with a prefab skid.
- All technical components are attached to this skid and tested so that assembly on site can be carried out quickly and easily.
- The basic skid can be expanded up to four pumps.
Module
A module is a complete prefabricated air scrubber in a plastic housing.
- The technical room is situated on the side of the ‘master’ module
- All technical parts are assembled and tested in this room so that installation on site can be carried out quickly and easily
- Modules are composed of segments of 2.4 m wide x 2.1 m deep
- A master module can be extended up to two extension modules
- A series is available up to thirteen segments
- Pipework between modules is included, but must be installed on site
Due to air capacities it is recommended to use built-in air scrubbers for poultry instead of modules, because of practical aspects regarding dimensions.
