Concept
Tank
Circular tank, 38m inside diameter. Height inside 18m. Eff. Waterheight 17m. Height outside 20m. Bottom with slope and center drain. Total volume 20.000m³
Construction
The tank will have a density app. 0,90 to stay steady and floating. Double hollow wall with a top floating ring for equipment. When the tank is emptied for water, it floats and can be easily moved from site to site or maintenance.
Capacity
Standing stock 60 kg/m³
Total biomass max 1.200.000kg
Feeding at max stock 1,25%
Max daily feeding 15.000kg
Water flow and treatment
Water treatment and pumping of Intake-Outlet water is placed in top float ring. For best balance and security, the water treatment is placed in 3 similar sections. All in top of tank, with good access. App. 50% of float ring is used for wet installations. Other 50 % is for dry Equipment.
Intake WaterFlow 15.000 m³/h is pumped through a system of UV- Chamber and Oxygenation Chamber. Inlet through the hollow space between walls. Oxygen is injected in a depth of 10-15 m. Water inlet in fishtank at 15-18 m in depth. Outlet water flow 5.000 m³/h is taken from bottom center drain and rinsed through a drumfilter and pumped out. 10.000 m³/h is running out through top sidedrains by gravity.
Total water exchange rate is 1 hour and 10 min.
Electro power
Maximum consumption at peak production
Pumping of water: 132kwh
UV-Desinfection intake water: 135kwh
Other equipment: 50kwh
Oxygengenerator: 300kwh
Total: 617kwh
Energy consumption - kwh/kg
Oxygen production
Demand 6.000 kg O2/day. Average 250 kg O2/hour. But an oxygen generator must handle higher peak loads of up to 320 kg/h.
The Oxygen generators for this capacity will use up to 360 kwh electro power at peak production.
