A technically sound UV plant retrofit is not just a module replacement. It requires recalculating dose, reviewing hydraulics, improving automation and adapting the new UV system to the existing civil works. This article explains how to modernize open-channel UV plants with lower risk and better long-term performance.

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.

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.

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, based in Madrid, has launched the NLQ 800 HPV, a high-power vertical open-channel UV disinfection system for municipal wastewater treatment plants. Its vertical UV modules are designed for both new projects and the retrofit of existing chlorine contact channels, combining 800 W low-pressure amalgam lamps, chemical-free automatic cleaning and intelligent power control to reduce energy use and OPEX.

Longking EnTech Europe has commissioned a high-efficiency NLO 2nd Generation ozone system at the Venta Alta Drinking Water Plant in Bilbao, boosting energy efficiency, advanced oxidation and drinking water quality.

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.
