Efficacy of Constructed Wetland in the Improvement of Effluent from Soba Stabilization Ponds, Khartoum, Sudan 2021

EasyChair Preprint no. 8095

Abstract

Background: Wetland is one of the natural treatment systems, where contaminants are removed via a range of natural processes mediated by complex interaction between water, plant, microorganisms, soil/gravel media and atmosphere. While utilizing the power of nature and energy from the sun, polluted water can be cleaned in sustainable way, with minimum operation and maintenance cost. Constructed wetlands (CWs) are planned systems designed and constructed to employ wetland vegetation to assist in treating wastewater in a more controlled environment than occurs in natural wetlands.
Methods: This is a descriptive study carried out in Khartoum state. Aimed to assess the role of constructed wetland in improvement of effluent characteristics from Soba stabilization ponds in Khartoum – Sudan.
A small prototype of a constructed wetland was constructed in an open area in Khartoum. The treatment is done by passing wastewater through substrate media that rely on physical, chemical, and biological processes for removal of contaminants.Samples were subjected to analysis in the laboratory.
Results: The study reached good results in effluent characteristics such as Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Total Suspended Solids (TSS), and Pathogens, which were removed by 85.4%, 95%, 98%, and 95%, respectively. And the performance is moderate in removing of Metal, Nitrogen, Phosphor, and Ions.
Conclusion: The system is most cost effective and sustainable.
This study recommended Stop discharge effluent of Soba Stabilization ponds directly into White Nile River, applying constructed wetland technique in treatment of wastewater in Sudan due to availability of wild lands, good climatic conditions that fit to the plant growth requirements, and also availability of plant species to be used in these systems .
