Client Profile
The client is a seasoned fish fry cultivation expert in Foshan with two decades of experience. To expand operations and enhance fry quality, the client constructed a brand-new modern hatchery facility. The fry stage represents the most vulnerable phase in aquaculture, demanding the strictest water quality standards. Pathogen infections and water quality fluctuations are the primary causes of high mortality rates. Therefore, the client urgently required a highly efficient, stable, and absolutely safe recirculating water treatment solution for fry to ensure the new facility’s high-standard operation.
Solution
Tailored to the client’s newly built Recirculating Aquaculture System (RAS) with a 100m³/hour treatment requirement and the unique demands of fry cultivation, we precisely matched a 100T-capacity integrated ozone water generator designed for aquaculture. The core of this solution lies in precise control, maintaining the ozone concentration in the aquaculture water within the optimal range of 0.1-1 PPM. This concentration effectively eliminates harmful bacteria and viruses in the water while ensuring absolute safety for the fry through its rapid decomposition properties.
Application Method
We integrated the ozone generator with the ejector (Venturi tube) in the client’s recirculating water system for efficient coordination. As recirculated water passes through the venturi, the instantaneous negative pressure generated internally automatically and efficiently draws in ozone gas. This creates a vigorous mixing process with the water flow, forming minute bubbles. This method not only achieves instantaneous ozone dissolution, significantly enhancing sterilization efficiency, but also features a simple structure and stable operation. It seamlessly integrates into the customer’s existing recirculating water piping without requiring complex modifications.
Core Product Advantages
Highly Efficient and Precise, Tailored for Fry Cultivation: Compared to conventional sterilization methods, the precise concentration control of 0.1-1 PPM is custom-designed for highly sensitive fry, achieving a perfect balance between “powerful sterilization” and “ultimate safety.”
Safe, Residue-Free, and Eco-Friendly: After disinfection, ozone rapidly decomposes into oxygen, leaving no chemical residues. This fundamentally eliminates the toxicity risks posed by traditional disinfectants to fry while increasing dissolved oxygen levels in the water, creating an optimal growth environment.
Multi-functional, comprehensive water quality optimization: Beyond sterilization, ozone effectively oxidizes and decomposes harmful substances like nitrites and ammonia nitrogen, degrades organic matter, and enhances water clarity. This multi-dimensional approach builds a stable, clean, and highly oxygenated ideal water environment for fry cultivation.
Project Value
By implementing this ozone solution, the client’s new hatchery established a robust water quality “firewall” from the outset of operations.
Significantly Improved Survival Rates: Compared to the old facility, the new plant is projected to achieve over a 20% increase in fry survival rates, effectively reducing economic losses from disease outbreaks.
Quality and Profitability Dual Wins: Fry raised in safe, clean water exhibit stronger constitution and vitality, earning the client higher product reputation and market competitiveness.
Streamlined Management: The stable water treatment system drastically reduces daily chemical interventions and manual water adjustment complexity, allowing this two-decade veteran to focus more intently on the hatchery process itself. This project not only secures the success of the client’s new investment but also injects powerful technological momentum into the long-term sustainable development of their business.
