United International Hydro Eng odor control systems are used extensively in wastewater treatment plant and pump lift station applications where odor removal is required.
These systems can be single or multiple stage units utilizing biological, wet scrubber and/or carbon media technologies. United International Hydro Eng odor control systems effectively eliminate up to 99.9% + of H2S, ammonia, mercaptan, as well as many other odors.
We also provide bio-trickling filters and biofilters, where an aqueous phase is trickled over the packed bed, and the packing is made of synthetic material. The trickling solution contains essential inorganic nutrients such as nitrogen, phosphorous, potassium, etc. and is recycled.
Biotrickling filters are the most effective type of biofilters for the treatment of compounds that generate acidic by-products, such as H2S. They can be built taller as compared to other types of biofilters. Extol Hydro offers the most comprehensive line of odor control solutions and services in the industry.
High levels of H2S can lead to odor complaints from the surrounding community and unsafe conditions for workers. United International Hydro Eng has provided odor and corrosion control solutions that prevent and remove hydrogen sulfide, protecting the integrity of infrastructure systems and preserving quality of life. Our technical expertise, reliable professional service network, and broad range of products and services allows us to provide the best solution to meet your needs.

Odor in wastewater systems is primarily caused by hydrogen sulfide (H2S), which is released in the form of a gas.
In addition, hydrogen sulfide accelerates corrosion in collection systems and wastewater plants, leading to dangerous leaks and costly repairs.
Applications for odor and corrosion control treatment include: collection systems, wastewater plants, and biosolids process.
Industrial scrubber systems are used to eliminate dangerous gases and particulate matter from process emissions, drawing on a range of technologies to “wash” exhaust before releasing it to the atmosphere. Scrubbers use several types of combustion technology to achieve these objectives, helping businesses meet compliance codes and environmental safety regulations.
Scrubber System Types
United International Hydro Eng experienced team of engineers, design professionals and production personnel have the skill and expertise to create scrubber systems that meet even the most demanding performance expectations. To that end, we will help you identify and configure a scrubbing technology that is crafted to meet your unique needs. The major types of scrubber systems include:

These scrubber systems use activated carbon which absorbs hydrogen sulphide from a gas by facilitating a chemical reaction in the scrubber tank.
In an electrostatic scrubber the aerosol particles and the scrubbing droplets are charged to opposite polarities.
These units uses virgin carbon of special kind that can be regenerated by water.
Wet type chemical scrubbers provide clean gases for various combustion processes. These popular scrubber systems are based on caustic (NaOH) treatment and provide unparalleled performance and efficiency.
This scrubber achieves all this while still achieving >98% H2S content at outlet.
The system, which initiates the scrubbing immediately, has an almost zero down-time ensuring maximum output and efficiencies. This extends its applications to systems where the gases are not available throughout the day and have frequent turn offs and turn ons during operation..
For pump stations that already have a powered ventilation system, our passive canisters can be integrated very easily.
The nozzle end of the stainless steel canister slips into any 4 inch socket style fitting and utilizes an “O” ring to seal the connection. Utilize a fabricated piping system of your own, terminated with a 4" PVC coupling or Fernco coupling, and add this canister to accomplish a custom configuration odor control unit. Carbon is included.
Each unit includes a base mounting ring. Mounting ring is made of 3/16" stainless steel with four holes for anchoring to a concrete surface. Four 3/8" SS wedge anchor are included. Legs are 12" tall and allow for some adjustment to assist with leveling the passive canister. Canisters are designed with a 4" inlet and are available in 16", 20" and 24" diameter canisters. Air exits the bottoms of the canister.
For canister CFM capacties, please refer to the chart located at the bottom of the "Powered Units" page.
When is it time to change out the Carbon? When it starts to smell!
Every system is different so the life expectancy of the carbon is not easily predictable. On average, the carbon will last one to three years. During regularly scheduled station maintenance, if a pungent order is sensed it is time to replace or rinse the carbon. Rinsing the carbon thoroughly with clean water regenerates the carbon to a half life.
