<p>The invention concerns a residual water treatment process, characterized in that it is carried out in close association with sports fields, public gardens, recreational areas, agricultural crops, etc. with the purpose of providing mutual benefits. According to the invention, quality of residual waters is improved up to tertiary treatment values by means of the economic resources generated by the creation of new green surfaces that do not require additional water supply due to the fact they grow on the green cover implanted on the beds of a conventional filtration-percolation tertiary treatment station. The method is characterized in that water is applied underground to the percolation beds for increased efficiency of the treatment (less evaporation losses), the green areas can be used even during irrigation and direct contact of users of said areas with residual waters is prevented.</p> |
