dc.description.abstract | The sustained expansion of agricultural industry in Colombian high-mountain has led to an increased size of
residues, especially untreated wastewater. This untreated water is an urgent matter for public and
environmental health, not only by its nutrient concentration (composed especially of food residuals and feces)
but also the presence of pathogens (virus, bacteria, etc.) which are discharged to the environment.
The overall objective of this work is to evaluate the effect of UV-treated wastewater from a high-mountain
fishery as culture media for the production of Chlorella vulgaris as a sustainable method for nutrient and water
recirculation on the fishery production system. The UV-canal efficiency was evaluated by the implementation
of an experimental factorial design (time, distance of the UV-lamps towards the canal, number of UV-lamps
and the sample concentration) using STATISTICA 7.0 software. Results shown that time (3 to 5 minutes) and
the number of lamps (3-4) of 15 Watts eliminate completely coliforms from the samples.
After UV-treatment the resulting water was test as culture media for C. vulgaris production by the adjustment
of C/N ratio (Sodium Carbonate/potassium nitrate) by the implementation of an experimental 23 factorial
design. Results shown that higher nitrate concentrations (>0,22 g/L) and moderate carbonate concentrations
(1 g/L) increase the final biomass concentration up to 4g/L in 20 days. | |
