Evaluation of the treatment of purified wastewater in the city of Bouira (Algeria)

Abstract

Wastewater reuse is a popular practice in some regions of the world, affected by water shortages. After purification techniques, wastewater can be used in several areas of irrigation and industry. Only, there are international standards declared by the World Health Organization for these waters discharged from the sewage plant. In this research, we tried to evaluate these purified wastewaters by choosing the wastewater treatment plant of Bouira. We took samples of raw water and purified water to perform common physico-chemical analyses such as (pH, turbidity, temperature, BOD5, and conductivity), whose purpose is to control the quality of water before and after treatment. This control operation lasted one month (February and March) of the year 2022. The results of the physico-chemical parameters of raw wastewater and treated wastewater are analyzed and compared with the thresholds set by the wastewater treatment plant of Bouira. At the end, we have shown that the treated water does not practically meet the standards of discharge, because the values of the physico-chemical parameters and the parameters of pollution exceed the standards, which does not encourage their reuse.

Industrial Investing as an Instrument of Sustainable Development in Algeria (Case in Bouira Province - Eastern Algeria)

“…By decision N013 of the 51st Session of the National Investment Council, dated 19/04/2011, the local authorities of Bouira province decided to create the Sidi Khalid industrial zone (Figure 5), Oued El Berdi in an estimated area of 193 hectares (Lamri et al, 2022b). Figure 5 shows us that the industrial zone is located on good quality agricultural land, endangering the farming area and reducing the area used for agriculture, thereby reducing the area's productivity , in addition to being close to the industrial zone with the municipal urban caucus (Lamri et al, 2022a).The Industrial Zone received 990750000 Dza in funding support under the Guarantee and Solidarity Fund for Local Communities in 2019. With respect of laying the floors and connecting them to various networks (gas, electricity, water) to help investors' their investment projects.…”
