FEILI Oxygen-Fed Ozone System Enhances Water Quality at Vietnamese Aquaculture Farm

A shrimp farm in Southern Vietnam has installed a FEILI oxygen-fed ozone generator to treat pond water, reduce disease pressure, and eliminate chemical disinfectants.

The farm operates intensive shrimp ponds with high stocking densities. Water quality is a constant challenge. Feed residue and shrimp waste release ammonia and nitrite. Without proper treatment, these compounds accumulate and stress the shrimp.

The farm previously used chemical treatments and frequent water exchange. Both approaches had drawbacks. Chemicals left residues. Water exchange was costly and wasted resources. Disease outbreaks still occurred.

The Solution: FEILI 30g/h Oxygen-Fed Ozone Generator

After evaluating multiple options, the farm selected a FEILI 30g/h oxygen-fed ozone system. The system includes:

• Air compressor and drying equipment

• Pure oxygen generator for maximum ozone output

• 30g/h ozone generator with stainless steel body

• Ozone-water mixing and reaction system

The system treats pond water continuously, injecting ozone through a sidestream loop. The ozone breaks down ammonia and nitrite, kills Vibrio bacteria, and improves water clarity. Then it decomposes to oxygen, leaving no residues.

Measurable Results

After three months of operation, the farm reported:

• Ammonia and nitrite levels: Significantly reduced

• Shrimp survival rate: Increased by 18%

• Chemical use: Eliminated entirely

• Water exchange frequency: Reduced by 60%

• Feed conversion ratio: Improved

"Ozone has transformed how we manage our ponds," said the farm owner. "The water stays clean. The shrimp grow faster. And we don't have to worry about chemical residues in our exports."

Why Oxygen Feed Matters

Feeding ozone generators with pure oxygen instead of ambient air delivers higher concentration and higher output.

Higher concentration means more effective treatment in less time. Higher output means the system can handle larger water volumes. For a commercial shrimp farm with multiple ponds, oxygen feed is essential.

Oxygen-fed systems also consume less electricity per gram of ozone produced, lowering operating costs.
