3.Enquiry:

A fishery contacted us requiring a tilapia hatchery and grow-out system. Details are as follows:

● Project area: 2002 square meters

● RAS system for tilapia hatchery and grow-out system.

● The water source for breeding is mountain spring water, and the water temperature is colder

● Including two systems: a tilapia hatchery system and a tilapia growing-out system.

● The breeding density is high, and aeration is needed  


 

4. Solutions :

●  Predesigned Layout  

●Inlet water treatment: 2 mechanical physical filtration (micro-filter and sand tank) + 2 sterilization devices (UV and ozone); Inlet water sterilization: UV sterilization strength 60mJ/cm2, specially designed ozone mixing device, ozone concentration 1.2PPM

● 3 sets of complete RAS systems for tilapia hatchery and growing-out

● A hatchery system has 48 food-grade blue PP tanks, specially designed hatching system for tilapia sinking eggs

● To ensures the sterilization effect, UV sterilization system with 40mJ/cm2 intensity are adopted and the mold in water are killed in time.

● Automatically controls the water temperature to optimize the incubation efficiency and the survival rate of seedling cultivation with a heat pump

● Specially designed low-pressure oxygenator maintains 6-9PPM of dissolved oxygen in the water and provides the most suitable dissolved oxygen environment for the baby fish.
