Ten clustered Phytoplan reactors (Greece)Along the years Separeco distributed numerous microalgae production plants to utilize in the fish farms producing  giltheads. These systems have been optimized for the production of two particular species of microalgae, universally utilized in this field:

  • Nannochloropsis;
  • Isochrysis.

The efficiency of the reactors developed in collaboration with the R&D company Exenia Group from Albignasego (Padova) allowed us to reach in this field productive efficiencies unreachable until short time ago.The benefits produced by this new cultivation system are:

  • Cells concentrations above 1.2 billions cells per ml;
  • Stable production without falls;
  • Drastic reduction of starter solutions production. The system is self regenerating for many cycles. It is necessary to regenerate the culture about once every 45/60 days;
  • Residues absence from the bottom of the ponds unlike happens with the commercial algae paste, which arises contamination risks;
  • The solution, once collected and stocked in a refrigerator at 5°C, can remain vital for almost 60 days;
  • This long last is to be attributed to the cells reaction at concentrations next to 800 millions cells/ml. In this situation, for a protection mechanism typical of Nannochloropsis, bacteriostatic substances decreasing the bacterial number are produced, reducing the larval mortality;
  • The necessary activity for the microalgae production is reduced by few hours per week;
  • The necessary surface for the installation of a 6 reactors cluster is only 110 x 220 cm;
  • Consumptions are reduced, there are only two 250 W bulbs per reactor.

 Quanti reattori servono per alimentare la mia avannotteria? (How many reactors are needed in order to feed my fish farm?) This question can be answered in two ways:Short wayIf the production period is annual, it is necessary to be equipped wit h1.2 reactors every 1 million fishes produced.Accurate wayIf the desired microalgae concentration in the production ponds is next to 800,000 cells/ml, it is necessary to be equipped with a reactor for each 10,000 liters.These considerations, translated in the daily operativeness, mean that only 8 liters of concentrated microalgae produced with the Fitoplan are necessary every day in order to feed a 10,000 liters pond, equivalent to 56 g dw. Il costo (Cost)The calculated cost of one liter of solution produced with Fitoplan, considering the manpower, the energy, the CO2 and the plant amortization cost, is around 0.5 EUR/l. At the end of the amortization period the cost is reduced to 0.3 EUR/l.Returning to the previous example, the feeding cost of a 10,000 l pond is 2.4 EUR/day. Hereunder it is possible to consult the comparative tables for the Nannochloropsis production.
