Mermaid-Aquaculture - Level-1
Operating principles1. The fish production basins Mermaid-Aquaculture are made ??of of highest quality and durable fiberglass (FRP), preferably as a Race-Way production tank. Due to our special tank drainage system design the tanks become self-cleaning. A higher number of production tanks allow a better pond management.
(A 200-T/pa catfish plant as "on-floor" installation, prepared for expansion to 400 tons of annual production.)
2. The reservoir and the Production tanks are equipped with alarm and sensor technology constantly monitoring the water, temperature, pH and oxygen values ?.
3. The daily amount of fresh water exchange in this re-circulating plant is only about 5.0 - 12% of the total volume of the system.
4. The used exchange water is highly recommended for irrigation and watering Greenhouses but could also completely cleared by biological treatment if required.
5. The internal recirculation of water through the filter and the production tanks is maintained by a number of in-line pumps of high safety standard.
6.In the submerged biological filters occurs the biological treatment and sedimentation of the organic waste. Before that coarse particles are removed gently by micro-mechanical filtration at 50, 80 or 100 µ.
7. In the trickling filter heavy inert gases and nitrogen are stripped out while the biological process of the water resumes.
8. Through the trickling filter a very effective natural oxygen re-saturation is achieved by high volume blower. For this reason a >95% O² saturation is reached plausible at all times.
9. The system is equipped with a self-starting generator and very effective alarm and sensor devices.
10. The filters are designed so that when a back wash becomes necessary to remove excessive biomass it is possible without disturbing the fish or interruption of the production.
11. The standard system is already prepared to receive an upgrade with an oxygen plant for the optimizing of the existing production or increase of future production.
