Ozone & UV Technologies for Advanced Water Treatment

Oxidation, Disinfection & Advanced Treatment Solutions

Longking develops ozone generation, ultraviolet (UV-C) disinfection and Advanced Oxidation Process (AOP) technologies for municipal and industrial water treatment applications.

Our technology portfolio covers the complete treatment chain, from ozone production and advanced oxidation to UV disinfection, allowing each system to be configured according to the actual water quality, treatment objective and operating conditions of the project.

Longking combines specialized process engineering, equipment technology, automation and system integration to develop solutions for drinking water, municipal wastewater, water reuse, industrial wastewater and process-water applications.

Through Longking EnTech Europe and the wider Longking Group, projects are supported by European engineering and project execution together with global R&D, manufacturing and industrial capabilities.

From individual treatment systems to large-scale integrated ozone and UV installations, the technology is selected and engineered according to the required performance rather than applying a single standard solution to every project.

NLO Ozone Generation Systems

Longking's NLO ozone generator platform covers applications ranging from compact treatment systems to large-scale municipal and industrial ozone plants.

Based on double micro-gap corona discharge technology and high-frequency IGBT power electronics, the NLO platform combines high ozone concentration, low specific energy consumption and modular system architecture.

Key Performance

• Up to 296 g O₃/Nm³ with oxygen feed

• Specific energy consumption from 7.5 kWh/kg O₃ with oxygen feed

• Up to 40 g O₃/Nm³ with dry-air feed

• Specific energy consumption ≤16 kWh/kg O₃ with dry air

• LOX, PSA/VPSA or dry-air configurations

• Modular architecture for compact and large multi-generator ozone plants

• Integrated PLC/HMI control, instrumentation and safety

Longking combines the generator with the required gas preparation, cooling, injection, contact, off-gas destruction, automation and process engineering to develop complete ozonation systems.

NLQ Open-Channel UV Disinfection Systems

Longking's NLQ platform provides modular UV-C disinfection solutions for municipal wastewater, water reuse and industrial water treatment.

The range combines low-pressure amalgam lamp technology, automatic quartz-sleeve cleaning, UV monitoring, dose pacing and PLC-based automation, with different architectures to suit the hydraulic requirements of each project.

NLQ Technology

• NLQ-H: horizontal architecture with 320 W lamps

• NLQ-V: vertical architecture with 320 W lamps

• NLQ-HPV: high-power vertical architecture with 800 W lamps

• Automatic pneumatic quartz-sleeve cleaning

• UV intensity and water-level monitoring

• Flow and/or UVT-based dose regulation

• PLC/HMI and SCADA integration

• Project-specific hydraulic and UV system design

Each installation is configured according to the actual flow, UVT, suspended solids, required UV dose, channel hydraulics and redundancy requirements.
