Liquid oxygen source/oxygen-enriched ozone generator
Features and Advantages
Micro-gap double dielectric barrier discharge (DBD) with glass dielectric – higher output under oxygen-fed operation
Outlet concentration several times higher than with air-fed operation – significantly improved dosing efficiency
Under oxygen-fed operation, specific energy consumption per kg O₃ is markedly lower than under air-fed – reduced operating cost
Flexible oxygen supply options: liquid oxygen (LOX), pressure swing adsorption (PSA), or vacuum pressure swing adsorption (VPSA)
IGBT high-frequency inverter power supply with DSP-based digital precision control
Complete process package: gas supply, ozone generator, cooling, dosing, off-gas destruction
All subsystems designed and manufactured as an integrated solution – clear responsibility and stable operation
Stainless steel electrodes with high-pressure-resistant glass tubes – long life and high reliability
Floating electrode design – reduced risk of dielectric breakdown
Air-cooled power supply and transformer – no water cooling lines, no leak risk

Founder’s Project Achievements
1. Municipal Wastewater Treatment
Jiaxing Joint Wastewater Treatment Plant
Project overview: A key municipal wastewater plant in Zhejiang Province, serving Jiaxing City and surrounding townships. Required to meet increasingly stringent effluent standards.
Solution: Fusshia large-scale ozone generators for advanced tailwater treatment. Ozone-based advanced oxidation enhances removal of refractory organic compounds. The project became a benchmark for large-scale ozone application in municipal wastewater treatment in China.
Siyang Wastewater Treatment Plant
Project overview: Receives industrial park wastewater and municipal domestic sewage. Complex water composition – conventional biological treatment struggled to achieve stable compliance.
Solution: Fusshia ozone generators installed after the secondary clarifier to oxidize and decompose refractory organic compounds.
Henghai New District Wastewater Treatment Plant
Project overview: A large new-build plant co‑treating municipal sewage and industrial wastewater, constructed under an EPC model. Wide service area and high treatment standards.
Solution: Multiple large-scale ozone generators configured, using ozone-based advanced oxidation to remove complex pollutants – significantly improved final effluent quality, providing robust protection for the regional water environment.
Guangdong (Zhaoqing) Dasha Wastewater Treatment Plant
Project overview: Phase I construction of a municipal WWTP serving local domestic sewage and some industrial wastewater. Stringent discharge standards.
Solution: Fusshia ozone equipment for tailwater advanced treatment. Ozone's strong oxidation capacity effectively reduces organic pollutants, laying a solid foundation for future expansion and upgrading.
2. Petrochemical Wastewater Treatment
PetroChina Jilin Petrochemical
Project overview: Large integrated petrochemical complex, generating complex wastewater with high levels of refractory organic compounds. Existing process could not meet discharge requirements.
Solution: Fusshia ozone generators combined with catalytic advanced oxidation for non‑selective oxidative breakdown of refractory organics. The project established a reliable technical route for petrochemical wastewater treatment.
3. Drinking Water Treatment
Beijing Guogongzhuang Water Treatment Plant
Project overview: A key supporting project of the Middle Route of the South-to-North Water Diversion, supplying water to southwestern Beijing. Extremely high requirements for effluent quality and operational reliability.
Solution: Fusshia ozone equipment configured as a pre‑ozone + main ozone process – oxidizes organic matter, improves coagulation conditions, and enhances water safety. A classic case of advanced treatment in a large-scale water plant.
Fuzhou Southeast District Water Treatment Plant
Project overview: Source water is river surface water with significant seasonal quality fluctuations. Conventional treatment could not guarantee stable effluent quality.
Solution: Fusshia ozone equipment for an ozone‑GAC (granular activated carbon) advanced treatment process – significantly improved key parameters such as permanganate index and ammonia‑nitrogen. The project served as a demonstration for subsequent water plants in the province.
Funing Chengdong Water Treatment Plant
Project overview: Raw water had issues including high organic matter, fluctuating ammonia‑nitrogen levels, and high color. Conventional treatment led to variable effluent quality.
Solution: Fusshia ozone equipment applied as both pre-ozone and main ozone – enhanced oxidation efficiency and promoted biofilm maturation in the activated carbon filters. Final effluent quality exceeded national standards with controllable operating costs.
