Enhancement of the free residual chlorine concentration at the ends of the water supply network: Case study of Souk Ahras city – Algeria

Abstract

The drinking-water supply sector has mostly targeted the water-borne transmission of pathogens. The most common method employed is the chlorination of drinking-water at treatment plants and in the distribution systems. In Algeria, the use of chlorine in drinking water treatment is a widespread practice. To enhance the concentration of the residual chlorine in the public water-supply system of a part of Souk Ahras city (Faubourg) (Algeria) known by its low concentration of the free residual chlorine (according to the water utility – Algérienne des Eaux: ADE investigation) especially at the point of use, practical steps were carried out. The method is a combination between numerical simulation using EPANET2 software and field measurements. Using statistical analysis the hydraulic model was calibrated and the observed values were very closer to the simulated results. The concentration was improved throughout the network after the injection of the appropriate dose.

Drinking water quality assessment using Principal Component Analysis: Case study of the town of Souk Ahras, Algeria

“…The second component consists of two elements namely ammonium (NH4) and nitrate (NO 3 − ); we can say that these waters are distributed to consumers without complete oxidation by chlorine. Generally, if chlorination is done properly, the ammonium concentration (ammonium ion) is zero [24,25,26].…”

Physicochemical Characterization of Drinking Water Quality of the Communal Water Distribution Network in Souk Ahras City/ Algeria

“…The pipes are from 63 to 160 mm in diameter as shown the (Figure 2). [18,19]. The system suffers from many problems, the most notable of which is the lack of continuous service.…”

“…The parameters that control the evolution of the water quality in the network are complex and have been the subject of extensive research [1][2][3][4][5][6][7]. Quality is a universal health problem, it is essential for life, but it can transmit diseases in the countries of all continents from the poorest to the richest.…”

Fractal-Heuristic Method of Water Quality Sensor Locations in Water Supply Network

“…The chlorine decay within the water supply network may lead to the degradation of water quality and, thus, poses potential microbial risks to humans. Therefore, it is important to maintain residual chlorine throughout the water supply network within the desirable levels [36][37][38]. It is also important not to exceed the recommended dose of chlorine as this can lead to the formation of disinfection by-products that are harmful to the human health.…”
