Abstract
Constructed Wetlands (CWs) are well known as an efficient treatment technology for many wastewater sources such as municipal and various industrial effluents. Different engineering designs such as horizontal and vertical flow and hydroponic channels can be implemented according to the required treatment strategies. Greywater and blackwater are also treated in CWs in Egypt and other countries. CWs can achieve high removal rates of various pollutants including total suspended solids, organic pollutants (COD, BOD), nitrogen compounds, phosphates, pathogenic contamination, as well as several heavy metals. There is a wide acceptance and interest in employing CWs due to their advantages such as simple construction, cost-effectiveness, low operation and maintenance cost, high ability to tolerate fluctuations in flow and inlet quality, high pathogens removal, potential for reuse and recycling, aesthetically accepted appearance. Several successfully full and pilot scale CWs are in operation in Egypt as well as in the Middle East and North African countries where the warm climate seems to favour the various CW processes and functions. This chapter presents existing full-scale CWs, hydroponic wetlands, as well as pilot plants using horizontal, vertical, and channel flow for the wastewater treatment in Egypt.
