Impact of treated wastewater on groundwater quality in the region of Tiznit (Morocco)
The Tiznit region has an arid to semi-arid climate. Rainfall is scarce and the reuse of wastewater for crop irrigation is common, and consequently groundwater can be contaminated by chemical and biological pollutants. A wastewater treatment plant is constructed with the aim of producing water suitable for reuse in agriculture and reducing groundwater pollution. The aim of this study is to assess ...

Potential for wastewater reclamation and reuse in Lebanon
Eleven major wastewater treatment plants are planned for construction along the sea coast of Lebanon to handle the flow from the major urban centres. The plants are expected to generate approximately 640,000 m3 of treated sewage daily, and the effluent is planned to be disposed into the sea. In the light of the water deficiency that the country would be facing in the coming years, the reuse of ...

Analysis of chemical reaction kinetics of depredating organic pollutants from secondary effluent of wastewater treatment plant in constructed wetlands
Four subsurface constructed wetlands were built to treat the secondary effluent of a wastewater treatment plant in Tangshan, China. The chemical pollutant indexes of chemical oxygen demand (COD) were analyzed to evaluate the removal efficiency of organic pollutants from the secondary effluent of the wastewater treatment plant. In all cases, the subsurface constructed wetlands were efficient in ...

Multi-stage constructed wetland systems for municipal wastewater treatment
In the present paper the detailed design and performances of two municipal wastewater treatment plants, a four-stage constructed wetlands (CW) system located in the city of Dicomano (about 3,500 inhabitants) in Italy, and a three-stage CW system for the village of Chorfech (about 500 inhabitants) in Tunisia, are presented. The obtained results demonstrate that multi-stage CWs provide an ...

Constructed wetland for water quality improvement: a case study from Taiwan
In Taiwan, more than 20% of the major rivers are mildly to heavily polluted by domestic, industrial, and agricultural wastewaters due to the low percentage of sewers connected to wastewater treatment plants. Thus, constructed or engineered wetlands have been adopted as the major alternatives to clean up polluted rivers. Constructed wetlands are also applied as the tertiary wastewater treatment ...

The application of improved flow diverter for first flush management
The paper presents the investigations on first flush phenomenon based on the total suspended solids (TSS) concentration measurement during selected rainfalls at central part of Czestochowa (Poland) and also the hydrodynamic model of the catchment. The model allows to present the conception of first flush management using an improved flow diverter Septurn. Flow diverters used in the separate sewer ...

Case Study | Techase 80% Sludge Feeding Application at Lingbi WWTP
This time, let me take you to Lingbi, Anhui, China to know more about Techase “80% sludge feeding directly” process. Conventional deep sludge dewatering projects generally need to control sludge MC at about 95%, and then start the final squeezing stage for deep dewatering. In this way, some sludge with 80% MC has to be diluted first which is more complex and expensive. Techase has ...

Domestic wastewater treatment by a constructed wetland system planted with rice
The experiments were conducted in four concrete laboratory scale free water surface constructed wetland units 1 m wide, 1.5 m long and 0.8 m deep. Paddy field soil was added to a depth of 0.4 m and rice seedlings (Oryza sativa L.) were transplanted into the units at a density of 25 plants/m2. Domestic wastewater collected from Chiang Mai University was applied into each unit via two different ...
