Product Announcement from Branch Environmental Corp.
For ground water or wastewater cleanup. Trace organics can be stripped out of the water by air moving countercurrent to the water.
Air Strippers come in several configurations. They can be provided as part of a package with vapor phase control, if necessary.
The most common types of Air Strippers we supply include:
Air Strippers for water purification...
Branch provides custom built Air Stripper units for removal of voc, ammonia, hydrogen sulfide and other volatile components from water. With our experience in complete systems, we can provide you with all of the related components and controls for a trouble free installation.
Counterflow Columns
Counterflow stripping columns are the most common design because of the high efficiencies that can be achieved, combined with the low air volume required.
Air volume is important, because in many cases the air will require further treatment before it can be discharged. The smaller the volume, the lower the supplemental equipment cost.
We offer designs using any of the available component suppliers. If you have a specific preference, we will be able to help you.
Ammonia Stripping
Where ammonia is present in water to be treated, you can remove it using air stripping technology.
By a combination of pH adjustment and temperature, we calculate the tower size for any required efficiency. The most common application is for waste water at ambient temperature. By increasing the pH to 11, removals in the 80-90% range can be provided.
With large systems, the discharge air will need treatment to collect the ammonia. We provide a closed loop system where the discharge air is treated with an acid wash to form a salt from the ammonia and the air is reused in the stripper.

Special Applications
Carbon dioxide, hydrogen sulfide and other soluble gases can often be removed using air stripping technology.
We have previously built units for many unusual applications. Recently, several units have been installed on MTBE. Information on stripping MTBE or other VOC compounds is available.

Branch Environmental supplies custom built pollution control equipment for industry. Our air pollution control equipment can clean up acids, organics, aerosols and mist to meet any emission control standards. Our equipment is also used for water treatment, including removal of volatile organics, ammonia and other gases.
Wet Scrubbers have been used on a variety of applications. Their ability to remove both solids and gases makes them suited to handle difficult applications.
The most common types of scrubbers we supply include:
Where insoluble organic vapors are present, Scrubbers will not work. Such vapors can be removed by thermal destruction. The result is usually harmless gases including water and carbon dioxide.
The most common types of systems we supply include:
- Thermal Oxidizers.
- Regenerative Thermal Oxidizers RTO
- Catalytic Oxidizers.
- Selective Catalytic Reduction.
For ground water or wastewater cleanup. Trace organics can be stripped out of the water by air moving countercurrent to the water.
Air Strippers come in several configurations. They can be provided as part of a package with vapor phase control, if necessary.
The most common types of Air Strippers we supply include:
The removal of oxides of nitrogen (NO/NO2) is a unique problem because of the difficulty.
Our selective catalytic reduction system uses ammonia to react with the NOx resulting in nitrogen and water.
Alternative systems using wet scrubbing are also available
Where difficult to remove aerosols are present in the air, a Fiberbed mist eliminator maybe the answer.
Fiberbeds are able to remove oil mist and smoke sized droplets from air.
Aeration Columns
We design and build custom fabricated mass transfer equipment for gas absorption and removal.
The most common type of aeration devices we provide are:
