The urban wastewater treatment station of the new city of Ali Mendjeli in the Wilaya of Constantine finishes its construction phase. With this project, SICE brings to the Algerian market its know-how in management of sewage plants. Specifically in this contract, SICE is responsible, not only for the design of the plant, but also for the supply of all the equipment, as well as the execution of all works (except civil ones). The company now starts the operation and maintenance of the plant phase for a period of two years.
This contract will have a great impact on the local community. The plant will supply a population of about 260,000 in the western part of the new town of Ali Mendjeli, in the province of Constantine, in the northeast of the country. In addition, the understanding of this project will create more than 100 direct and indirect jobs and, once built, will require the labor of about 25 people in a fixed way for their operation.
The WWTP will have a screening chamber, an initial pumping station, pre-treatment consisting of discharge of thick and thin solids and decanters and cleanser-degreases by aerated channels, secondary treatment by prolonged aeration process with nitrification-denitrification (2 lines) and final disinfection of the effluent by chlorination. The WWTP will also have a treatment line for the produced sludge, where it will be thickened by gravity and then dehydrated to reduce the final volume of the sludge.
