Branch Environmental provides a wide variety of custom fabricated air cleanup equipment including Scrubbers, Thermal Destruction systems (Oxidizers), special N0x Cleanup equipment and Vapor Phase Carbon systems. The air pollution control equipment to be used for removing acids, organic vapors, particles, or a combination of these from large or small applications.
More details are available on the individual product pages. Our equipment is used for cleaning water by aeration to remove volatile organics, ammonia and other gases from water. Air is most commonly used to contact the water and transfer the small amount of contaminants that are present however we can also use other gases.

Venturi scrubbers are used to remove very small particles; mist and can also remove gases. The open design eliminates opportunities for the solids buildup and minimizes maintenance. Venturi scrubbers can also absorb gases such as Sulfur Dioxide or others that react with neutralizing chemicals. The scrubber can handle high temperature gases and variable gas rates by use of an adjustable throat design.
Jet Venturi scrubbers can remove dust and gas simultaneously. Their advantage is the ability to handle high concentrations of gases such as Chlorine or other water soluble gases. In many applications, the Jet Venturi can be used without any additional fan. Jet Venturi scrubbers use the energy from the liquid sprayed into the Venturi to create a pull on the gas drawing it into the scrubber.
As the amount of organics in the air decrease, you have to add more supplemental heat. One way to minimize this is to use a Catalyst. Catalysts reduce the temperature required for combustion. For example the operating temperature for a catalytic unit may be in the 600°F / 300°C range. This would reduce the operating cost compared to Direct Thermal Oxidation if the VOC is very low in concentration.
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.
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 stripping columns are the most common design because of the high efficiencies that can be achieved, combined with the low air volume required.
