ABSTRACT
This chapter presents the general description of Samaha wastewater treatment system, the different parts of the physical model, the measuring devices, and the arrangements for experiment requirements, as well as properties of the used media. It describes the experimental procedures, the plants cultivation process, the water sampling, the used laboratory tests and measuring instruments, the modeling of experimental data, and finally equations used for hydraulic and performance evaluation. Generally, physical model supported by experimental and field data gives reliable principles for the specialists. Since horizontal subsurface flow (HSSF) constructed wetlands supported by uncommon biofilm carriers are relatively new to unreliable field data, hence experimental work has found a scope in the present project. The HSSF wetland cells were established and tested for two stages; the first one is the set up stage and the other is the steady stage conditions. Several experimental preparations and procedures were carried out to construct the HSSF wetland system.
