Abstract Life Cycle Assessment was used to evaluate onsite wastewater treatment systems (OWTS): aerobic unit (ATU) with reinforced concrete (C.ATU) and HDPE (H.ATU) tank; constructed wetland (CW) three biochar concentrations in the substrate (0%; 10, 20% v:v), dubbed CW.BC0, CW.BC10 CW.BC20, respectively. CML 2001 SimaPro® impacts of 1 m3 wastewater. The OWTS were compared on their overall envi...

In Tunisia, olive mill wastewater (OMWW) locally named ‘margine’ constitutes a serious problem due to its huge amount, of about one million ton per year, and the high pollutant load resulting in excessive chemical oxygen demand (COD) values presence phytotoxic antibacterial polyphenols. The most common treatment OMWW was storage evaporation ponds which are authorized but uncontrolled. Thus, it ...

The swelling capacity of novel hydrophilic gaskets used in geomembrane cutoff walls and infrastructures is critical for decreasing the flow rates contaminated groundwater. This study investigated behavior, relaxation characteristics, rates, micro-morphology a gasket with different testing liquids. radial tests were performed using device modified from single-lever consolidation instrument. A mo...

The purpose of this work is to design a biodigester with high density polyethylene (HDPE) geomembrane material which will be effective in recycling biodegradable waste and produces both biogas organic liquid fertilizer. A tubular trapezoidal designed, following by the fabrication 300 litter’s prototype tarpaulin. After running air water tightness system, quantified are introduced observed for p...
