A Wet Scrubber is an emission control device that abates particulate (PM) or gases using a scrubbing liquid. The type of scrubbing liquid used is dependent on the target contaminants that need treatment. The dirty exhaust stream is introduced into the scrubber vessel and interacts with the scrubbing liquid. Here, the contaminated stream undergoes a chemical reaction or becomes captured by the scrubbing liquid before blowdown.
Particulate Dust Scrubbers are wet scrubbers that target particulate matter and comprises both Venturi and Multi-Vane Scrubber systems. These systems are suitable for processes with fine dust or sticky residues since they use liquid to collect the contaminant in a sump for blowdown.
Sub-type of particulate dust scrubbers that integrate a venturi throat into the design to accelerate the process exhaust stream, leading to high removal of particulate matter in batch and continuous-type applications.
High-efficiency wet particulate scrubbers that can treat gas streams with moisture and/or high temperatures. They offer higher removal efficiencies using little energy with a relatively small footprint.
These wet scrubbers reliably remove gaseous compounds such as ammonia, chlorine, and sulfuric acid from industrial exhaust streams.
Chemical Gas Scrubbers that typically use sulfuric acid (H2SO4) to neutralize the ammonia.
Chemical gas scrubbers that use an alkaline scrubbing liquid to strip chlorine from your process waste stream.
Chemical Gas scrubbers that use liquid caustic to neutralize sulfur-based substances in your process stream.
What is the pollutant you are trying to treat? If it is a chemical such as ammonia, sulfuric acid, or chlorine, you will need to choose a chemical gas scrubber. These scrubbers use packed bed media to distribute the appropriate scrubbing liquid through the dirty exhaust stream so that a chemical reaction can occur to neutralize the contaminant. If multiple pollutants are present, it may require a multi-stage combination system.
In addition to the initial capital cost of a wet scrubber, other control technology considerations include ongoing operating costs (i.e., utilities and maintenance expense), equipment life, and reliability.
Dry dust collectors equip air filters to capture the pollutants, which require constant changing. The use of liquid in wet scrubbers allow for handling of more difficult contaminants, such as combustible dusts, sticky residues, soluble gases, and fine particulate that is too small for filter capture.
Wet scrubbers are effective for continuous and batch-type operations. Our technical team will work with you to make sure the technology selected can handle your process.
We design our scrubber systems based on the requirements of the project. Depending on the composition of the process stream, a wet scrubber can be constructed from FRP or stainless steel.
