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.

World Water Day 2025 focuses on Glacier Preservation—highlighting increasing variability in water availability. This article connects the theme to water resilience and reuse, and explains how engineered ozone generator systems and UV disinfection systems can support reuse-ready multi-barrier treatment trains.

Longking finalized the acquisition of Fujian Newland EnTech, reinforcing leadership in ozone generators, UV disinfection and AOP solutions. This article explains why Newland EnTech Europe is now Longking EnTech Europe, what changes for customers, and how the integration strengthens our long-term capabilities in water and environmental treatment.

Longking EnTech Europe completed a 15 kg/h LOX-fed ozone generation system for the East Bay Drinking Water Treatment Plant in the Philippines (50,000 m³/day), integrating NLO ozone generators, energy-optimised control, robust cooling, porous diffusers and PLC-governed ozone destruction.

Longking EnTech Europe delivered a turnkey 100 kg/h LOX-fed ozone generator system for Bouregreg DWP in Rabat, Morocco—supplying Rabat, Casablanca and Salé. The installation includes three NLO 30K generators, CFD-optimized contact chambers, automated dosing across nine chambers, porous diffusers, PLC-controlled ozone destruction and comprehensive safety systems.

Reference project in Mexico: Longking EnTech Europe commissioned a dry-air ozone generation system for the Madín II drinking water plant to support supply for the Metropolitan Zone of the Valley of Mexico. The installation includes two NLO ozone generators (2 × 7.5 kg/h), UV spectrophotometer control loops, air compression and treatment, closed-circuit cooling, dome diffusers, PLC-controlled ozone destruction and advanced safety systems.

Cryptosporidium is chlorine-resistant, so utilities rely on multi-barrier drinking water treatment. This article explains how UV and ozone generator systems strengthen Crypto-resilient design—covering CT/contacting basics, safety and bromate considerations, and how Longking’s NLO ozone generators support stable, automated utility-scale ozonation.

Longking EnTech Europe was awarded the supply of a 160 kg/h LOX-fed ozonation system for El Ahogado WWTP in Jalisco, Mexico (via Mitsui). The project includes filtration and ozone disinfection for 3,250 L/s and supports a 1,000 L/s expansion benefiting more than 5.2 million inhabitants, featuring NLO-2G ozone generators and advanced automation for optimized energy and oxygen use.

Two-stage ozonation reference in Bilbao: Longking EnTech Europe supplied a LOX-fed ozone generation plant for Venta Alta Drinking Water Plant featuring NLO ozone generators (2 × 20 kg/h). The solution combines pre-ozonation with high-efficiency injectors and intermediate ozonation (before activated carbon) using porous dome diffusers to strengthen multi-barrier drinking water treatment.

Flagship ozonation upgrade at Santillana DWTP (Canal de Isabel II, Madrid): a centralized 90 kg/h ozone generator system with 3×30 kg/h NLO units supplying pre-ozonation and intermediate ozonation. The project included CFD-optimized contact chambers, high-capacity ozone destructors, SRIC closed-circuit cooling, automatic dosing, full SCADA integration and SENTINEL remote monitoring.

Madín II DWTP (Mexico) ozonation reference for ZMVM: dry-air ozone generator system with 2×7.5 kg/h NLO ozone generators, dual air compression/treatment trains, UV spectrophotometer control loop, closed-circuit cooling and dome-type diffusers for efficient ozone transfer to contact chambers.
