The main pilot equipment includes the following:
UV/Hydrogen Peroxide
UV/Ozone/Hydrogen Peroxide
UV Photolysis
UV Thin-Layer Disinfection Equipment
UV Thin-Layer Cyclone Oxidation Equipment
Ozone Catalysis
Conducting a water treatment pilot test is a necessary step in the transition to engineering scale-up after completing a small-scale laboratory test and determining the technical route. Its core objectives are threefold: ① Verify the stability of pilot test parameters under continuous flow conditions at the m³·d⁻¹ scale;
② Obtain calibration data for scale-up factors (residence time, UV power density, oxidant dosage, byproduct control, etc.);
③ Form the basis for the process package and commercial quotation for subsequent 10–100 m³·h⁻¹ demonstration units.
The following process has been used in pilot project validation for numerous domestic companies (including pharmaceutical, dye, pesticide, TDI, and other companies dealing with high-COD, salt-containing wastewater) and can be directly used as a blueprint for their SOPs or technical agreements.
I. Project Startup
1.1 Technical Briefing
1.2 Signing of the Pilot Plant Technical Service Agreement
1.3 On-site HSE Briefing

2.1 Process Route
• Mainstream: UV/H₂O₂ (or UV/O₃, UV/H₂O₂/O₃, UV/PS) homogeneous system
2.2 Required Units
2.3 Instrumentation and Control
III. On-site Installation and Commissioning
3.1 Installation Period: 1–2 weeks (can be shortened to 3 days for skid-mounted integrated equipment).
3.2 Commissioning Steps: Clean Water Test, Low-Load Operation, Gradual Switch to Raw Water Operation
IV. Continuous Operation and Data Collection
4.1 Design of the Operating Condition Matrix
4.2 Analysis Indicators and Frequency
V. Data Organization and Process Package
5.1 Key Scale-up Parameters
5.2 Pilot Plant Report Contents (for Owner/EIA/Expert Review)
① Wastewater Source and Properties;
② Process Route and Plant Photos;
③ Continuous Operation Curves;
④ Energy and Material Consumption (kWh·kg⁻¹ COD, kg H₂O₂·kg⁻¹ COD);
⑤ Byproducts and Toxicity Changes;
⑥ Issues and Solutions;
⑦ Demonstration Plant Investment and Operating Cost Estimation (CAPEX/OPEX)
VI. Completion and Handover
• On-site dismantling or conversion to a demonstration unit
• Technical briefing meeting: Hand over the operating manual and spare parts list to the owner's process, instrumentation, safety and environmental protection, and maintenance departments.
