Longking EnTech Europe will supply a Longking NLQ-32 H open channel UV disinfection system for the Villafranca de los Barros WWTP in Spain, enabling chemical-free treated wastewater effluent disinfection.

Longking EnTech Europe highlighted ozone-based micropollutant removal and quaternary wastewater treatment at IFAT Munich 2026. This article explores the revised EU Urban Wastewater Treatment Directive, the role of ozonation in advanced treatment, oxidation by-product management and Longking's integrated engineering approach for municipal and industrial wastewater applications.

Modernizing an existing open-channel UV disinfection system does not always require rebuilding the plant. Discover how Longking EnTech Europe evaluates UV retrofit projects, including hydraulic compatibility, UV dose recalculation, selection of NLQ-H, NLQ-V and NLQ-HPV systems, automatic cleaning, PLC/SCADA integration and lifecycle costs.

Real ozonation efficiency depends on more than ozone generator capacity. This article explains five key factors that determine system performance: feed-gas selection, ozone transfer efficiency, contact chamber hydraulics and CFD, cooling and automation, and long-term maintenance and monitoring.

In open-channel wastewater UV systems, dose alone is not a design basis. Reliable disinfection depends on the real operating window formed by UVT, suspended solids, flow and channel hydraulics.

Longking EnTech Europe announced its participation at IFAT Munich 2026, highlighting two water treatment technologies: NLO-LITE compact ozone generators and NLQ-HPV high-power vertical UV disinfection systems. The announcement focused on efficient system integration, hydraulic design, automation and operational reliability for municipal and industrial water treatment applications.

A technical design guide to ozonation and ozone-based AOP for EDC/micropollutant control. Covers matrix drivers, dose and contacting logic, off-gas safety, BAC/GAC polishing, verification/commissioning, and what to specify for ozone generators—incl. Longking NLO integration.

Sotillo de la Adrada upgrades drinking water pre-ozonation with a compact 1 kg/h NLO LITE ozone generator fed by PSA oxygen, ceramic diffusers and full safety systems.

UV disinfection in wastewater is rarely limited by lamp power alone. Stable performance depends on UVT variability, particle shielding (TSS/turbidity), hydraulics, and fouling control. This article explains why a multi-barrier approach (polishing/filtration + UV) delivers consistent compliance—and how Longking’s NLQ-H and NLQ-HPV open-channel systems are engineered for predictable dose under real effluent conditions.

Europe is moving endocrine disruptors (EDCs) from “emerging concern” to structured monitoring and upgrade planning in both drinking water and wastewater. This technical insight explains what utilities should specify now—indicators, sampling points, verification—and why ozonation + polishing (BAC/GAC) is often the most defensible barrier train, enabled by stable ozone generation with Longking NLO systems.

A year of consolidation and positive integration: Longking EnTech Europe strengthens its ozone and UV platform for the European water market and sets clear priorities for 2026.

Longking EnTech Europe commissioned a 160 kg/h ozone treatment system at El Ahogado Wastewater Plant (Mexico) with MITINFRA. Designed to support NOM-001-SEMARNAT-2021, the integrated package (generation, diffusion, automation, off-gas destruction and cooling) strengthens disinfection, color removal and toxicity reduction

Longking EnTech Europe introduces the NLQ-HPV Series, a high-power vertical open-channel UV disinfection system for municipal wastewater treatment and water reuse. Featuring 800 W low-pressure amalgam lamps, 16-lamp modules, automatic mechanical cleaning, UV intensity monitoring and intelligent power regulation, NLQ-HPV provides a modular platform for large wastewater treatment plants, new installations and technically feasible retrofit projects.

Longking EnTech Europe commissioned a 40 kg/h ozone system at the Venta Alta Drinking Water Plant in Bilbao, Spain. The installation uses two NLO20 oxygen-fed ozone generators integrated into pre-ozonation and intermediate ozonation stages, with plant automation and SCADA integration

Ozone is a key technology in modern multi-barrier drinking water treatment, enhancing disinfection, oxidation, and downstream performance. Learn how ozone strengthens safety, efficiency and regulatory compliance in potable water processes.

Choosing between LOX, PSA and dry air is a key engineering decision in an ozone system. This guide compares the three feed-gas alternatives and explains their impact on ozone concentration, energy consumption, equipment, oxygen logistics, redundancy and lifecycle cost.

Ozone treatment performance depends on more than ozone production. This technical article explains how gas concentration, diffuser design, water depth, T10, contact chamber hydraulics, CFD and water chemistry influence ozone transfer and overall ozonation performance.

Discover the differences between Longking's NLQ-H, NLQ-V and NLQ-HPV open-channel UV disinfection systems. This technical guide compares horizontal and vertical module configurations, 320 W and 800 W amalgam UV lamps, automatic cleaning, power regulation and SCADA integration. Learn how wastewater quality, treatment capacity, hydraulic conditions and maintenance requirements influence UV system selection for municipal wastewater treatment, water reuse and retrofit projects.
