Feili's
Ozone Machine For Wastewater Treatment represents our most advanced industrial category, engineered for facilities that require reliable, chemical-free water purification at scale. As a National High-Tech Enterprise with nearly 40 ozone technology patents and 14 years of manufacturing experience, Feili designs these systems for demanding applications including industrial effluent treatment, municipal wastewater plants, and livestock farm water recycling. Unlike chemical disinfection that leaves harmful by-products, ozone treatment breaks down organic pollutants, eliminates pathogens, and oxidizes heavy metals without adding to the environmental burden.
Ozone is one of the most powerful oxidants available for water treatment. It reacts with contaminants 3,000 times faster than chlorine and decomposes back into oxygen, leaving no chemical residues. A properly sized Industrial Ozone Generators system can reduce chemical oxygen demand (COD), eliminate color and odor, and achieve complete pathogen inactivation in a single treatment step. Feili's wastewater ozone systems feature durable construction, energy-efficient corona discharge technology, and smart controls for automated operation. Whether you manage a textile dyehouse, a food processing plant, a chemical facility, or a municipal treatment works, there is a Feili ozone solution designed for your wastewater challenges.
How Ozone Wastewater Treatment Works
| Stage | Process | Result |
| 1 | Ozone generated from ambient air or oxygen | High-concentration O₃ gas |
| 2 | Ozone injected into wastewater stream via Venturi | Gas dissolves into water |
| 3 | Ozone reacts with organic compounds | Contaminants oxidized to CO₂ and H₂O |
| 4 | Ozone destroys bacteria and viruses | Complete pathogen inactivation |
| 5 | Residual ozone decomposes to oxygen | No chemical by-products |
Key Applications
Industrial Effluent Treatment
Factories discharge wastewater containing dyes, oils, solvents, and organic compounds. Ozone oxidation breaks down these pollutants, reducing COD and BOD levels to meet discharge regulations. Unlike chlorine, ozone does not create toxic chlorinated by-products.
Food Processing Wastewater
Meat, dairy, and vegetable processing generates high-organic-load wastewater. Ozone treatment eliminates pathogens, reduces odor, and breaks down fats and proteins, making water suitable for discharge or reuse.
Livestock & Poultry Farm Wastewater
Animal operations produce wastewater high in ammonia, pathogens, and organic matter. An Ozone Generator for Livestock application can treat lagoon water, reduce odor, and eliminate bacteria before land application or discharge.
Municipal Wastewater Plants
Small to medium communities need cost-effective disinfection without chemical handling. Ozone provides primary or tertiary treatment, eliminating bacteria and viruses while oxidizing pharmaceuticals and personal care products that pass through conventional treatment.
Textile & Dye Wastewater
Dyehouse effluent contains color, surfactants, and organic compounds. Ozone decolorizes wastewater and breaks down refractory organics, enabling water reuse and reducing discharge fees.
Technical Specifications by System Size

| Medium | 50-200 g/h | 800W-3.2kW | Food processing, livestock |
| Large | 200-500 g/h | 3.2-8kW | Industrial, municipal |
| Industrial | 500-2000+ g/h | 8-32kW | Large municipal, chemical |
Frequently Asked Questions
Q: How is ozone different from chlorine for wastewater treatment?
A: Ozone reacts 3,000 times faster than chlorine, leaves no chemical by-products, and decomposes back to oxygen. Chlorine creates trihalomethanes (THMs) and other disinfection by-products that are harmful to aquatic life. Ozone also oxidizes a wider range of pollutants, including pharmaceuticals and personal care products.
Q: What contaminants can ozone remove from wastewater?
A: Ozone effectively treats bacteria (E. coli, Legionella), viruses, protozoa (Giardia, Cryptosporidium), organic compounds, phenols, cyanide, pesticides, surfactants, dyes, odor compounds (hydrogen sulfide, ammonia), and iron/manganese. It also reduces COD and BOD levels.
Q: Do I need to add chemicals after ozone treatment?
A: In many applications, ozone alone is sufficient. However, some facilities use ozone as a pre-treatment followed by biological filtration or activated carbon. Others combine ozone with hydrogen peroxide (advanced oxidation process) for recalcitrant compounds.
Q: What is the typical contact time required?
A: Contact time depends on the contaminant and ozone concentration. For disinfection, 2-10 minutes is typical. For COD reduction or oxidation of complex organics, 15-30 minutes may be required. Feili engineers can calculate specific contact requirements for your wastewater profile.
Q: How much does an ozone wastewater system cost to operate?
A: Operating costs include electricity for ozone generation and, if used, oxygen feed. Ozone from air costs approximately $0.10-0.20 per gram. Ozone from oxygen costs approximately $0.05-0.10 per gram. No chemical purchase or handling costs. Labor costs are minimal with automated systems.
Q: Is ozone safe for wastewater treatment operators?
A: Yes, when proper safety systems are installed. Feili systems include off-gas destruction to prevent ozone release, ambient ozone monitors, and emergency shutdown controls. Standard industrial hygiene practices apply.
