Industrial Wastewater Treatment
Advanced Ozone & AOP Technologies
Ozone and AOP systems are transforming industrial wastewater treatment by providing powerful, selective oxidation for pollutant degradation and effluent reuse.
At Longking EnTech, we design systems that combine ozone oxidation, UV photolysis, and hydroxyl radical generation, ensuring full compliance with discharge regulations.
Key Benefits
Enhanced Biodegradability: Converts complex organics into biodegradable compounds for easier biological treatment.
COD & AOX Reduction: Significant decrease in Chemical Oxygen Demand and halogenated organics (AOX).
Decolorization & Deodorization: Removes color and odor from effluents, improving water quality.
Toxicity Reduction: Eliminates pesticides, phenols, cyanides, and other hazardous compounds.
Water Reuse Readiness: Treated effluent suitable for reuse or safe discharge.
Our high-concentration ozone generators (up to 296 g/Nm³) combined with CFD-optimized contact reactors guarantee maximum mass transfer and oxidation efficiency.
Pulp & Paper
Sustainable Bleaching and Effluent Treatment
In the pulp and paper sector, ozone provides a chlorine-free oxidation process for bleaching and effluent purification, reducing environmental impact and chemical dependency.
Key Advantages
Elemental Chlorine-Free (ECF) Bleaching: Eliminates harmful chlorinated by-products.
Reduced COD & AOX: Minimizes load on biological treatment systems.
Improved Whiteness: Achieves high brightness with lower chemical consumption.
Effluent Treatment Integration: Combines with biological and filtration stages for cleaner discharge.
With ozone-based bleaching and UV-AOP systems, Longking EnTech helps paper mills meet sustainability and production quality goals simultaneously.
Food & Beverage
Hygiene, Safety & Product Quality
Our ozone and UV disinfection systems ensure microbiological safety in beverage bottling, food processing, and packaging industries, without chemical residues or taste alteration.
Applications
Bottling Line Sterilization: Ozone-in-water systems sanitize PET and glass containers.
Packaging Disinfection: UV tunnels ensure aseptic filling and packaging.
CIP Integration: Clean-In-Place systems with ozone reduce detergent use and rinsing time.
Storage and Air Purification: Ozone eliminates airborne contaminants and odors.
These sustainable solutions help producers meet ISO 22000, HACCP, and FDA food safety standards while minimizing operational costs.
Off-Gas Treatment
Odor and NOx Reduction
Industrial emissions often carry odors and nitrogen oxides.
Longking’s ozone and AOP-based oxidation systems neutralize these compounds effectively, ensuring compliance and cleaner air.
Applications
Odor Control: Eliminates VOCs and hydrogen sulfide.
