Product Information

Key Features

  • Three photobioreactor ranges from Varicon Aqua — Phyco-Flow tubular arrays, Phyco-Pyxis fixed volume vessels and Phyco-Bubble laboratory columns
  • Phyco-Flow typically operates at cell densities 5 to 10 times conventional culture methods, and uses the patented tube self cleaning mechanism to run for prolonged periods without cultures crashing
  • Phyco-Pyxis is a closed, fixed volume reactor from 1000 up to 4000 L, fabricated in GRP with a removable top, top overflow for harvesting and a valved bottom outlet for draining down
  • Phyco-Pyxis is internally illuminated by LED optimised to deliver maximum PAR, avoiding the waste heat and waste energy of conventional light sources
  • Mixing is by aspirated air with CO2 injection under pH control, so photosynthetic oxygen is displaced and dissolved inorganic carbon stays available
  • Influent is disinfected by in line chemical dosing or UV at 2500 to 3000 L per hour per system, with nutrient added by proportional in line dispensers rated 10 to 3000 L per hour
  • Main species grown are Nanno, tetra, chlorella, scenedesmus, chaetoceros, Isochrysis, neochlorus, pavlova, haema and benthic diatoms
  • Sizing: choose on culture volume and light delivery together — Phyco-Bubble at 3 to 25 L for bench work, Phyco-Pyxis at 1000 to 4000 L where an internally lit closed vessel suits the site, and Phyco-Flow where the highest density and a self cleaning tube matter most and the array is built to the production requirement. Varicon Aqua does not publish light path, illuminated surface area or a PAR value for any range, so confirm the illumination package with Fresh By Design. Other sizes and configurations are available on request
