Guangdong Zhengzhou Environmental Protection Technology Co., Ltd. offers a portfolio of efficient, reliable solutions for malodor control. Our core approaches are bio-deodorization filter towers and high-energy ion deodorization equipment.
1. Bio-deodorization Filter Tower (Biofilter)
Working principle: Microorganisms metabolize organic matter in the exhaust stream, converting malodorous compounds into harmless end products. The process includes adsorption and uptake of odor precursors by the biofilm, followed by biodegradation to carbon dioxide, water, and other non-hazardous species.
Applications: Suited to low-concentration, large-volume odor streams, such as emissions from wastewater treatment plants, landfills, and similar facilities.
Technical advantages:
- High removal efficiency for a broad range of odor species, including hydrogen sulfide and ammonia.
- Low operating cost and straightforward maintenance.
- Environmentally sound operation with minimal risk of secondary pollution.
2. High-energy Ion Deodorization Equipment (High-energy ions)
Working principle: High-voltage ionization of air generates large quantities of positive and negative ions. These species react with contaminants, disrupting odor molecules. Ions associate with odor compounds to form transient species that are subsequently oxidized or reduced to harmless products.
Applications: Well suited to medium- to high-concentration malodors, including volatile organic compounds (VOCs) and process odors from chemical manufacturing and related industries.
Technical advantages:
- Rapid, effective reduction of malodorous gases.
- Compact equipment with flexible installation options.
- No liquid waste or bulky secondary residues; simple day-to-day operation and maintenance.
Together, these two lines of technology enable comprehensive odor management across industrial sectors. We also design hybrid trains where field conditions demand them—for demanding or variable loads,bio-deodorization and high-energy ion deodorization may be combined to maximize removal performance and meet stringent air-quality targets.
