<p>An improved continuous photobiological process for the tertiary treatment of waste waters, without any waste, is carried out by supplying, in a first step, the waste waters with B-group vitamins and oligoelements, by submitting them, in a second step, to the metabolic action of photosynthetical microorganisms, particularly of "Phycophyteae", genus Green seaweeds, at 15 - 30 DEG C and pH 6,5 - 8, in a highly aerated and illuminated ambient, and by separating - in a third step - the reclaimed water and the formed biomass from the immature biomass, which is recycled to the first step. The plant essentially consists of a collecting tank [1] and a small vitamin B and oligoelements feeding and dosing device [2], inserted in a piping, delivering the waste waters to a particular multiple reactor [3], consisting of transparent modular elements, supplied with flood lighting and air insufflation means [4] and two separators [5] of the reclaimed water and the mature biomass from the immature biomass; and recycle and discharge means.</p> |
