The SandWand system is two 2-inch trash pumps connected to a stainless steel wand that is worked by one operator. The operator simply rocks the SandWand back and forth on the surface. One pump injects water through a 1.5 inch hose to a nozzle in the wand directed into the bottom and the other pump draws off the water /sand/ silt slurry leaving ...

2. Physical characteristics of straightened, sand-bed reaches of the South Fork Obion River in western Tennessee, USA that were rich in LWD were compared with those in similar reaches where debris had recently been …

Riparian areas are widely recognized as the main areas for carbon sequestration and nitrogen pollution removal, while little is known about the effects of the respective sand mining activities on riparian zones. In this study, the effects of sand mining activities on the soil organic carbon (SOC) st …

The manganese oxide effectively oxidized Mn (II) in the water to Mn (III) and Mn (IV). MOCS exhibited great performance for Mn (II) removal in the filter bed experiment. The results suggested that ...

The grain size analysis of marine sediments is considered as a basic tool in the marine environmental research. In particular, information on sediment characteristic is needed, for example, for ...

This paper brings together the effects of river sand mining on the physical, biological, chemical, and anthropogenic environment through a systematic literature review.

The SEP-iSYS™ Cyclonic Sand Removal System (CSRS) offers these features in a very compact, lightweight and cost effective package. The SEP-iSYS™ CSRS is a compact sand removal system that combines a flow stabiliser system with a cyclonic desander to desensitize it from upstream transient and multiphase conditions.
