This project deployed a 1kg/h oxygen-fed ozone generator for intensive Vannamei shrimp (Penaeus vannamei) farming in Guangdong, China. The farm covers 8 high-level ponds with total water volume of 6,500 m³. Traditional probiotics and chemical disinfection failed to control vibrio, nitrite accumulation and organic turbidity, leading to frequent EMS risk and low shrimp survival rate.
Case Details
Project Overview
This project deployed a 1kg/h oxygen-fed ozone generator for intensive Vannamei shrimp (Penaeus vannamei) farming in Guangdong, China. The farm covers 8 high-level ponds with total water volume of 6,500 m³. Traditional probiotics and chemical disinfection failed to control vibrio, nitrite accumulation and organic turbidity, leading to frequent EMS risk and low shrimp survival rate.
Key Equipment & Process
After 7-day continuous side-stream treatment: nitrite reduced by 89.2% to safe level; total vibrio decreased by 92.7%, effectively inhibiting early mortality syndrome (EMS). Water transparency increased significantly, organic sediment and foam reduced obviously. The shrimp survival rate rose from 72% to 87%, and the harvesting cycle shortened by 8–10 days.
