Compact Ozone Generation for Lower-Capacity Water Treatment Applications
Overview
Longking NLO LITE is a compact ozone generation platform designed for lower-capacity municipal and industrial water treatment applications where reduced footprint, simple integration and reliable ozone production are key requirements.
Based on Longking's double micro-gap corona discharge technology, NLO LITE brings the core ozone-generation principles of the NLO platform into a compact, modular format suitable for water reuse, industrial process water, pilot installations, aquaculture and containerized treatment systems.
With ozone production capacities from 0.5 to 1.5 kg O₃/h, NLO LITE can be configured for oxygen feed from PSA or LOX, or treated dry-air feed, depending on project requirements. With oxygen feed, ozone concentrations of up to 296 g O₃/Nm³ and specific energy consumption of ≤8 kWh/kg O₃ can be achieved, depending on the selected model and operating conditions.
Technology & Design
NLO LITE uses Longking's double micro-gap corona discharge technology with borosilicate dielectric, providing efficient ozone generation within a compact, plug-and-play platform.
The system can be configured for oxygen feed from PSA or LOX, or treated dry-air feed, according to the required ozone production, concentration and available plant utilities.
NLO LITE uses a closed-loop water-cooling system to provide controlled heat removal from the ozone-generation process and support stable operation under continuous service conditions.
Key Technical Characteristics
Ozone production: 0.5–1.5 kg O₃/h
Ozone concentration: up to 296 g O₃/Nm³ with oxygen feed
Specific energy consumption: ≤8 kWh/kg O₃, depending on model and operating conditions
Ozone-contact materials: AISI 316L / PTFE
Feed gas: oxygen from PSA/LOX or treated dry air
Cooling: closed-loop water
Control: integrated PLC with optional HMI
Communications: Ethernet capability for remote monitoring and system integration
The final configuration is selected according to the required ozone production, feed-gas source, operating conditions, cooling utilities and plant-integration requirements.
Cooling System
NLO LITE uses a closed-loop water-cooling system to remove the heat generated during ozone production and maintain suitable operating conditions for the ozone-generation modules.
Closed-Loop Water Cooling
The cooling circuit is designed to provide controlled and continuous heat removal from the ozone generator while minimizing water consumption through recirculation.
Depending on the project configuration, the cooling system can be integrated with the plant's existing cooling-water utilities or supplied as part of a dedicated closed-loop circuit.
The final cooling arrangement is defined according to ozone production capacity, inlet cooling-water temperature, ambient conditions and site utilities.
Control & Automation
Each NLO LITE ozone generator is equipped with an integrated PLC-based control system for automatic operation, process monitoring and safety management.
An optional touchscreen HMI can provide local access to operating parameters, alarms and system status, while Ethernet connectivity enables integration with external control and monitoring systems.
Control Functions
Automatic start/stop sequences
Ozone output and power control
Monitoring of key operating parameters, including temperature and cooling-water flow
Safety interlocks and alarm management
Local operation through optional HMI
Ethernet connectivity for communication with external monitoring or plant-control systems
The control architecture can be adapted to the requirements of the overall ozone installation and coordinated with auxiliary equipment such as feed-gas preparation, cooling systems and ozone application equipment.
Applications
NLO LITE is designed for water-treatment projects requiring compact ozone generation, flexible integration and continuous automatic operation.
Water Reuse
Ozone can be integrated into tertiary and advanced treatment processes for oxidation of residual contaminants, colour and odour compounds, as well as in combined ozone/AOP treatment trains when required by the project.
Municipal Water & Wastewater Treatment
Compact ozone generation for drinking-water, wastewater and reuse applications where the required ozone demand falls within the NLO LITE operating range.
Industrial Process & Wastewater Treatment
Suitable for ozone-based oxidation in industrial process water, wastewater and reuse systems, with the final ozone dose and treatment configuration defined according to water quality and treatment objectives.
Aquaculture & RAS
NLO LITE can be integrated into recirculating aquaculture systems (RAS) for ozone-based water-quality management and oxidation processes, with the ozone application and residual control engineered according to the specific system.
Pilot & Demonstration Plants
Its compact configuration makes NLO LITE suitable for pilot plants, demonstration systems and process-development projects requiring controlled ozone generation under representative operating conditions.

Why Choose Longking NLO LITE
NLO LITE combines compact ozone-generation equipment with Longking's engineering and system-integration capability, providing a practical platform for lower-capacity municipal and industrial water-treatment projects.
The system can be configured according to the required ozone production, feed-gas source, cooling conditions, control philosophy and plant-integration requirements, allowing the ozone generator to be incorporated into a complete treatment solution rather than treated as an isolated piece of equipment.
Through Longking EnTech Europe, projects can include support for system definition, integration engineering, automation coordination, commissioning and lifecycle services, backed by the manufacturing and R&D capabilities of the Longking Group.
Project-Specific Engineering
Final equipment selection should be based on the actual water characteristics, ozone demand, required dose, contact system, operating conditions and available utilities.
For each project, Longking can define the appropriate NLO LITE configuration and its integration with the complete ozone-treatment system.
