All the physicochemical analyses of the samples (compost, manure and treated wastewater), carried out in the physico-chemical chemical analysis laboratory at the wastewater treatment plant, revealed that the compliance with both Tunisian standards NT 106.20 and NT 106.03. To highlight the effectiveness of the compost, a comparative comparative study of "Geranium" growth was carried out in two two series of pots (the first with compost and the second with cattle manure). cattle manure). Growth monitoring revealed an improvement in internode length, as well as an increase in the number of buds number of buds and flower buds in the plant studied, when it was on compost than on manure.
