The main goal of this thesis is the assessment of the clogging degree in the horizontal subsurface flow constructed wetland of Martinlongo and Barrada WWTP, included in Algarve Multi-Municipal Sanitation System Despite of constructed wetland treatment processes being natural and constructed wetlands easy to operate, clogging phenomena can be quite complex and challenging in a way that it is nec...

Several different types of constructed wetland systems are being used as decentralized treatment systems including surface-flow, subsurface-flow, vertical-flow, and hybrid systems. Archetypical wetland systems have design strengths and weaknesses, and therefore it should be possible to design combined (integrated) systems to optimize a number of important treatment processes. This study provide...

Constructed wetlands have become a good alternative to urban and industrial wastewater treatments. Because of the many interactions between the different parts that form the wetland, the design of these systems used to be very complex so a good design tool is required. Hybrid constructed wetlands mix the aerobic and anaerobic properties of vertical and horizontal subsurface flow constructed wet...

This study investigated the efficiency of a sequential system involving surface flow and vegetated sub-surface constructed wetland (CW) in treatment Brewery Wastewater. Six experimental CW (2 4 subsurface flow) control (1 2 with 200 mm depth 19.05 diameter granite 100 sharp sand as substrate were used for experiment. The CWs planted locally available macrophytes: water hyacinth (Eichhornia cras...

Abstract Subsurface flow constructed wetland (SSFCW) is widely adopted for the removal of BOD 5 and TKN from greywater. The design SSFCW normally based on thumb rules or using a first-order reaction kinetic model. However, applicability this model system/environment-specific which necessitates assessment potential other models. In present study, experiments were planned during initial establish...
