Dimensioning of a mini RAS system for a sea horse project
We were contacted by a costumer that wanted to breed sea horses which is a sea water specie.
Before, he used to breed sea horses near the sea but it was not very convenient at all so he decided to move the farm closer to the city and his home downtown. He then had to transfer the sea water to his farm from time to time. So he decided to build a RAS to save as much water as possible.
For the adult sea horses, each tank house around 10 pairs. The system is designed to handle both adult and baby sea horses.
Since the sea horses don’t like a too high flow and water speed, the system is dimensioned for 5 m³/h. Maximum flow is 10 m³/h.
The total water volume is about 50 – 60 m³ and the retention time is about 10 -12 hours.
Density weight/m2: 20 species
Flow: 5 m3/h
Retention time: 10-12 hours
