Reduction of pathogenic elements within the irrigation water treatment.
Biolight SA in conjunction with prestigious Chilean institutions such as the CNR (National Irrigation Commission), CENMA (National Center for the Environment) and INIA (Institute of Agricultural Research) has developed experiences of disinfection with ultraviolet light of canal waters for their use in the irrigation of vegetables, berries and fruit trees, proving its success and application.
The water intended for irrigation must meet the following characteristics:
– Free of chemical elements : It must comply with the maximum concentrations of chemicals and a pH within the established range.
– Specific conductivity and total dissolved solids : the established parameters must be met, which vary according to the type of crop to be irrigated.
– Bacteriological Requirements : The content of fecal coliforms in irrigation waters for the cultivation of vegetables and fruits that grow at ground level, must be less than or equal to 1000 per 100 ml.
Waste water must be treated prior to disinfection activities, in order for the action of any disinfectant to be effective.
The reduction of pathogenic elements is a very important stage in the treatment of irrigation water since it affects both downstream users and the environment.
