There has been a paradigm shift towards reclamation of wastewater from high cost to low cost effective technology for treatment of sewage and resource utilization for economy driven activities.Under appropriate conditions, sewage fed fisheries would reduce the cost of fish production by utilizing the sewage induced natural plankton and become cost effective because of savings through chemical f...

The automatic reclamation of storage for unreferenced objects is very important in object databases. Existing language system algorithms for automatic storage reclamation have been shown to be inappropriate. In this paper , we investigate methods to improve the performance of algorithms for automatic storage reclamation of object databases. These algorithms are based on a technique called parti...

Abstract High-concentration organic wastewater has become a great challenge for treatment due to its toxicity and non-biodegradability. Traditional water methods focus on removing or destroying pollutants rather than considering the high-concentration as resource. As an ambitious sustainability goal, resource recovery from achieve zero liquid discharge (ZLD) attracted widespread attention. Here...

Desertification leads to decrease in the ecosystem C pool and attendant reduction in Soil Organic Carbon (SOC). Reclamation of sandy land in arid and semi-arid has a high potential to increase carbon sequestration and improving soil quality. Our objective as to examine the changes in the soil carbon sequestration and soil properties of two soil layers (0–20 and 20-50 cm) under two types of recl...

introductioncurrently, treated industrial wastewater is discharged to the environment in most industrial towns in iran. it is, however, a potential water resource for produce industrial process water. for reach this reuse application, further treatment would be needed. nowadays membrane separation processes are becoming quite popular in wastewater treatment and reclamation, since they combine p...

Surface coal mines prior to 1950 in the USA were generally left without any reclamation. As government regulations advanced since then, mine operators were required to backfill the area and plant grasses or trees. After the federal Surface Mining Control and Reclamation Act (SMCRA) was passed in 1977 in the USA, mine operators were required to conduct pre-mining analyses of the site and to desi...

The shortage of waste landfill space for waste disposal and the high demand for fill materials for land reclamation projects in Singapore have prompted a study on the feasibility of using spent copper slag as fill material in land reclamation. The physical and geotechnical properties of the spent copper slag were first assessed by laboratory tests, including hydraulic conductivity and shear str...

Memory management is one of the most complex aspects of modern concurrent algorithms, and various techniques proposed for it—such as hazard pointers, read-copy-update and epoch-based reclamation—have proved very challenging for formal reasoning. In this paper, we show that different memory reclamation techniques actually rely on the same implicit synchronisation pattern, not clearly reflected i...

Water reclamation can be one of the solutions when trying to solve the global water shortage. In the dry region Beaufort West, South Africa is a water reclamation plant supplying the inhabitants with drinking water, treated from wastewater. It is, however, important to evaluate the risks connected to this technology. The aim of this study was to conduct a chemical risk assessment in order to id...
