Pilot Plants – Essential for Ozone & AOP Process Optimization

Pilot Plants for Ozone and Advanced Oxidation – Essential Tools for Process Optimization

Overview

Longking EnTech Europe designs and operates advanced ozone and AOP (Advanced Oxidation Process) pilot plants that allow real-world evaluation of oxidation performance before full-scale implementation.

These pilot units provide engineers and operators with critical process data on ozone transfer efficiency, reaction kinetics, and contaminant removal — enabling the definition of optimal design parameters for municipal and industrial water treatment systems.

By bridging the gap between laboratory analysis and full-scale engineering, Longking’s pilot plants ensure that each project is technically validated, cost-efficient, and operationally robust.

Pilot Study Objectives

Each pilot study is custom-designed according to project-specific goals and site conditions.

Typical objectives include:

• Ozonation and AOP Performance Evaluation: Testing at different process stages to quantify oxidation efficiency and organic matter removal (TOC, DQO, color, odor, micropollutants).

• Determination of Ozone Demand: Defining the exact ozone dose required for desired oxidation or disinfection levels under real operating conditions.

• Reaction Pathway Analysis: Assessing the influence of temperature, pH, and water matrix composition on treatment performance.

• Optimal Integration Point: Identifying the most effective location for ozone or AOP within the existing treatment line.

The outcome of these studies allows Longking engineers to scale up with precision, reducing design uncertainty and optimizing investment decisions.

Pilot Plant Capabilities

Longking’s pilot units are engineered for maximum flexibility, control, and data accuracy, enabling detailed process characterization.

Key technical features:

• Adjustable Ozone Production Capacity (1–100 g/h).

• Integrated Oxygen Feed & Cooling Systems.

• Online Sensors for Ozone Concentration, ORP, pH, Temperature.

• Data Logging & Remote Monitoring.

• Modular Design: Compatible with pre-treatment and post-oxidation units (e.g., filtration, UV, adsorption).

• Safety Features: Leak detection, automatic shutdown, and ozone destruction unit.

All pilot systems comply with European electrical and safety standards (CE marked) and are supported by Longking’s technical specialists throughout the testing campaign.

From Pilot to Full-Scale Implementation

Data obtained from pilot testing is directly applied to the design of full-scale ozone or AOP systems:

• Process Validation: Confirms expected performance and compliance with regulatory targets.

• Design Optimization: Refines reactor configuration, contact time (CT), and ozone generator sizing.

• Operational Strategy: Defines automation setpoints, dosing logic, and off-gas handling requirements.

• Cost & Energy Optimization: Ensures treatment performance with minimum ozone consumption.

This structured approach guarantees that full-scale systems are efficient, validated, and tailored to each project’s real operating conditions.

Applications

Longking’s pilot plants are used to test and optimize ozone and AOP processes for:

• Municipal wastewater treatment – color, odor, and microcontaminant removal.

• Drinking water treatment – disinfection, taste/odor correction, organic oxidation.

• Industrial effluents – oxidation of refractory organics, cyanides, or phenols.

• Water reuse projects – validation of oxidation as tertiary barrier.

• Research & development projects – feasibility studies and demonstration plants.

By combining engineering precision, process data analysis, and on-site flexibility, Longking EnTech Europe’s pilot plants are indispensable tools for optimizing ozone and AOP performance.
They transform theoretical designs into proven, field-validated processes — ensuring that each ozone system built by Longking is technically justified, energy-efficient, and sustainable from the very first day of operation.
