High-capacity ozone generators and turnkey ozone systems for drinking water, wastewater and reuse. Learn key design choices (LOX vs PSA), contacting efficiency, automation, safety and lifecycle support with Longking’s NLO platform

World Water Day 2025 focuses on glacier preservation and water security. This article explores how water reuse, ozone, UV and multi-barrier treatment can contribute to more resilient water-management strategies.

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.

Explore the complete ozone-plant architecture at Madín II in Mexico, including dry-air preparation, two NLO ozone generators, closed-loop cooling, ozone application, off-gas destruction, automation and safety integration.

Technical guide to Cryptosporidium control in drinking water using UV, ozone and multi-barrier treatment, covering UV validation, ozone CT, contact hydraulics, water quality and key design requirements.

El Ahogado WWTP reference in Jalisco, Mexico: a 160 kg O₃/h LOX-fed Longking NLO-2G ozone system engineered for high-flow municipal wastewater treatment and disinfection.

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.

Longking EnTech Europe supplied and commissioned a 90 kg/h ozone system at the Santillana Drinking Water Plant in Madrid, Spain. The installation combines 3 × NLO30 oxygen-fed ozone generators with pre-ozonation and intermediate ozonation, CFD optimization of contact chambers, off-gas destruction, closed-circuit cooling, PLC/SCADA integration and SENTINEL remote monitoring.

Madín II drinking-water reference in Mexico: two dry-air-fed NLO A7.5K ozone generators providing 15 kg O₃/h total installed capacity for a 47,800 m³/day municipal treatment plant.

LIFE PHOENIX reference in Spain: a containerized Longking ozone-generation system with PSA oxygen supply and two ozone generators, integrated into a flexible multi-barrier platform for advanced wastewater treatment and agricultural reuse research.

Piszolla (Alba de Tormes, Spain): 20-foot containerized, LOX-fed ozone system (3 kg/h) engineered from pilot-test data to control geosmin and off-flavours (taste & odour). Advanced dosing automation, contacting/diffusion design and SENTINEL remote support.

The IPCC 1.5°C report highlights major climate challenges for the waste and water sectors. This article examines the implications for water and wastewater utilities, with a focus on water reuse, multi-barrier treatment, and the role of ozone and UV within advanced treatment trains.

Longking EnTech Europe supplied a fully integrated, plug & play containerized ozone generator system for Axens Group in Salindres (France): 2 kg/h LOX-fed ozone production at 150 g/Nm³, with chiller cooling, ozone measurement, O₂/O₃ leak detection and PLC automation.
