Reuse

With continuing growth in the reverse osmosis water treatment industry and the finite lifespan of the membranes, the number of membrane modules requiring disposal is expected to drastically increase over time. This study aimed to provide a quantitative assessment of the environmental impact from memb

In order to reach the UN Millennium Development Goals for significantly reducing the number of people without access to adequate sanitation, new holistic concepts are needed, focusing on economically feasible closed-loop ecological sanitation systems rather than on expensive end-of-pipe technologies

Wastewater treatment performance of the combined process of upflow anaerobic sludge blanket (UASB) reactor and sequencing batch reactor (SBR) was studied. An experimental study has been conducted investigating the performance of the system under different operating conditions. Three experimental run

Scaling and fouling of membranes are an on-going performance issue for most plants This presentation outlines innovations in speciality chemicals designed to inhibit membrane scaling and fouling and to clean membranes where deposition has occurred. There is an increasing trend to treat recycled wast

The enhancement of water quality by constructed wetland systems is increasingly practiced world wide. The use of a treatment train consisting of an up-flow anaerobic sludge blanket (USAB) reactor followed by free water surface and subsurface flow constructed wetlands in series has been investigated.

This paper discusses several options to achieve sustainability in wastewater treatment in urban areas of the Mediterranean region. The first was by decentralizing the treatment rather than installing expensive sewer systems that combine and increase the volume of the waste. The next involved choosin

The availability of freshwater to meet different water needs has raised serious concerns in the last decades all around the world. Water scarcity, deterioration of quality and increasing demand have led to the development and use of alternative sources of water. Reclamation and recycling are now con

Secondary effluents (SE) contain xenobiotic organics (XO) that may cause disturbance in living organisms. When SE are reused in agriculture, contamination of soils by XO is of concern. In this study, SE used for irrigation/aquifer recharge in Oued Souhil area (Nabeul, Tunisia), as well as effluents

This study aims to find a new die purification for wastewater reuse. It consists of the filterability of biological sludge exits of the wastewater treatment plant at Staoueli (Algeria) on porous membranes. The membrane used is a mineral membrane M2 Carbosep (15 Kg/mol). we are interested for the fir

Sanitation techniques that are low cost and non-conventional are the adequate solution for the treatment of wastewater for small communities in rural areas. This work presents the experience of the ONEP used in some small and medium sized communities. Also, within the framework of the sanitation pro
