Opis:: The wastewater treatment plant of Settat city uses the natural lagooning technology, which requires low maintenance cost and little technical expertise. The purpose of this study was to evaluate the stability of plant performance during two years of operation (2019 and 2020), as well as the safety of its treated wastewater for reuse in agricultural irrigation. The results of this study show that the biochemical oxygen demand (BOD5), chemical oxygen demand (COD) and suspended solids (SS) did not exceed the Moroccan standards for discharge. They also show a good stable pollutant load reduction with a mean of 86.44%, 86.89% and 74.61%, for BOD5, COD and SS, respectively. On the other hand, microbiological characterization classifies the treated wastewater as "B" quality water, because the fecal coliform numbers exceed the requirement for "A" quality (1000 CFU/100 ml).

Opis:: Questions of reuse of drainage water and wastewater of rice systems on the example of rice irrigation systems are determined. The technological scheme, which saves water and energy resources during the irrigation of crops in the rice system, is proposed. Calculations of economic efficiency of water circulation technology in the Danube rice irrigation systems (RIS) with drainage water and wastewater (DWW) dilution with fresh water in the ratio of 1 : 1 showed that the net profit will amount to UAH 26,266.5 per 1 ha, while the dilution in the ratio of 1 : 2 – to UAH 26,161.5 per 1 ha. Complementary net profit will accordingly amount to UAH 1,337.8 and 1,231.5 per 1 ha. The most perspective technique to use DWW in rice irrigation systems is their reuse with dilution with fresh water at a ratio of 1 : 1 or 1 : 2. This ratio corresponds to most indicators for which was done an evaluation of water that is supplied for irrigation. Also this ratio does not lead to deterioration of soil salt regime.

Opis:: This work aims to evaluate the treated wastewater from the activated sludge treatment plant in the City of Sidi Bel Abbes (North-Western Algeria) which is required for reuse in irrigation. The control of irrigated areas downstream is done based on a pedological study. Physico-chemical analysis such as (pH, BOD₅, COD and SS) indicate results in Algerian and international standards required by the WHO. The Sodium Adsorption Ratio and Electrical Conductivity values of the treated wastewater belong to the C3-S1 class. The treated wastewater has a fairly good microbiological quality that meets Algerian standards. The helminth eggs are practically absent. The concentrations of heavy metals are much lower than the limits prescribed in the Algerian decrees. Therefore, the overall processing plant efficiency is satisfactory and has the characteristics of a good treated water quality for reuse in the field of irrigation while protecting the environment. The pedological study of the soil samples shows that the most dominant fraction is undeveloped calcimagnetic. The planned irrigation plain covers an area of about two thousand hectares. Depending on the crops to irrigate; the development and nature of the necessary or recommended improvements, the proposed irrigation perimeter could be classified into five categories in which only three categories are irrigable. Water projects have been proposed to ensure the irrigation of three subdivided sectors.
