NLQ-HPV Series – High-Performance Vertical UV Disinfection System
Longking NLQ-HPV Series – Advanced High-Power Vertical UV Disinfection for Open-Channel Applications
Overview
The NLQ-HPV Series from Longking EnTech Europe represents the most advanced generation of open-channel UV disinfection systems developed for large municipal and industrial wastewater treatment plants.
Equipped with 800 W high-power amalgam lamps and a hydraulically optimized vertical design, the NLQ-HPV system achieves superior disinfection efficiency while minimizing head loss and operational costs.
Engineered for continuous operation in harsh outdoor environments, it ensures maximum microbiological safety, electrical protection, and minimal maintenance requirements — all essential for critical water infrastructure.
High-Power Vertical Design for Maximum Efficiency
The NLQ-HPV builds upon the proven NLQ-V vertical architecture, incorporating new-generation high-intensity 800 W lamps with higher UV output and improved energy conversion efficiency - up to 2.5 times higher UV dose output compared to conventional 320 W modules.
Its cross-flow vertical arrangement guarantees uniform UV dose distribution across the entire channel profile, ensuring consistent microbial inactivation even under fluctuating flow rates.
Technical advantages include:
High-Power UV Lamps (800 W): Achieve superior disinfection rates with reduced module count.
Optimized Flow Dynamics: CFD-validated geometry for uniform velocity distribution.
Compact Installation Footprint: Ideal for retrofits and space-constrained facilities.
Enhanced Electrical Safety: All connections located above water level.
Easy Maintenance: Lamp replacement without removing the module from the channel.
This results in a compact, efficient, and robust UV system optimized for municipal wastewater, drinking water and reuse applications.
Intelligent Control & Automation
Each NLQ-HPV system integrates the Longking Intelligent Control Platform (ICP) — a PLC-based automation system with HMI interface and full SCADA connectivity.
Main control features:
Continuous UV intensity and dose monitoring.
Lamp hour and status tracking with predictive alerts.
Automatic pneumatic cleaning system using compressed air actuators.
Remote control and diagnostics for integration with plant DCS or SCADA.
This intelligent automation ensures constant disinfection performance, optimized energy consumption, and regulatory compliance (EU, USEPA, WHO).
Mechanical & Material Design
All UV modules are built in AISI 316L stainless steel with high corrosion resistance and mechanical robustness. The system is designed for outdoor installation with IP-rated control cabinets, air-conditioning units, and EMC-compliant electrical systems.
Every component, from quartz sleeves to lamp holders, is optimized to ensure long service life and easy maintenance — minimizing lifecycle costs for the end user.
Key Applications
Municipal Wastewater Treatment – tertiary disinfection ensuring bacteriological compliance.
Drinking Water Plants – final UV barrier against pathogens (e.g., Cryptosporidium, Giardia).
Industrial Process Water – guaranteed microbiological control and reuse reliability.
Water Reuse Systems – sustainable and chemical-free treatment for irrigation and industrial loops.
