Fish Basins

. Fish basins

2. Drum filter to remove all particles > 30 micron

3. Rinse water pump which rinses with system water

4. Water storage sump under drum filter and trickling filter

5. Pump to rotating nozzles above trickling filter; 100% of water flow which means approximately 1 to 1.5 times per hour all water in basins is treated

6. Trickling filter is a biologic filter that’s removes NH4 and NO3

7. Heat exchanger on intake water

8. Pumps to bring water to fish basins (eventually by-passing O2 reactor)

9. Oxygen reactor to bring water on over saturation with Oxygen

10. Pump to up-flow filter and UV unit; approximately an extra 15% of water volume is filtered by this unit per hour

11. Up-flow filter; to remove smaller particles and also for nitrification

12. Ultra violet unit to treat all the water from Up-flow at least 1x per 6 hours all system water is treated by up-flow and UV

13. Sump to store all waste water from drum filters and up-flow filters

14. Pump in waste water sump to de-nitrification tower and waste water treatment unit

15.De-nitrification filter with ethanol dosing pump

16. Mixing unit to bring polymer and iron chloride in the system to get flocks of dirt

17. Belt filter to split “cleaned waste water” from the sludge

18. Storage of “dry sludge” and cleaned waste water for discharge

19. Intake of new water to replace waste water and evaporation

20. Submerged heat exchanger in sump or in water supply to fish basins

21. Heating unit

22. Ventilator on top of trickling filter to de-gas and ventilate building and filter

23. Pure Oxygen from storage tank or O2 generator
