Performance comparison and erosion prediction of jet pumps ...
Sand erosion in jet pump. As mentioned above, the newly designed jet pump is used to transport water with entrained sand particles. The sand particles flow along the water and impinge the wall of the equipment resulting in erosion, which may result in a reduction of efficiency due to the geometry change, even damage of the jet pump....
INDIAN RIVER COUNTY'S PLAN FOR PRESERVING .
Beach restoration, sometimes referred to as beach renourishment or sand pumping, is one method used to stabilize a critically eroded beach. Beachquality sand is dredged from an offshore borrow area and pumped onto the beach or mined form an upland source and transported to the beach by truck. Heavy machinery is used to shape the placed sand into...
Blog | Sump Pumping Groundwater Eng
Oct 08, 2014· While sump pumping has great potential for effective groundwater control, it is important to realise that in unfavourable ground conditions the method can lead to major problems. These problems arise primarily because the flow of water into the excavation, and then to the sumps, can have a destabilizing effect on finegrained soils....
USA Method of pumping and processing phosphate ...
The invention relates to the broad subject of dewatering phosphate clay wastes and has for its primary object the drainage of existing phosphate slime settling ponds and the reclamation of the drained ponds through the use of the processed slime as a land fill having adequate drainage characteristics. Another object of the invention is to provide a processing step for phosphate slimes which ......

There are three major ways by which shorelines are stabilized. These methods are listed below, in decreasing order of environmental safety. Beach Replenishment. If you must repair a beach, this is probably the most gentle approach. Replenishment consists of pumping sand onto the beach and building up the former dunes and upper beach....

Graphite India limited (G . Division) Method of Installation of GRP Pipe ð• Proper backfilling should be done in 150 mm to 300mm lifts depending on backfill material and compaction material, 300mm lifts will be adequate since gravel is relatively easy to compact. Sand needs more compaction effort s....
DEWATERING CONTROL OF GROUNDWATER
The available methods of groundwater control fall into the following basic groups: 1. Surface water control like ditches, training walls, embankments. Simple methods of diverting surface water, open excavations. Simple pumping equipment. 2. Gravity drainage. Relatively impermeable soils. Open excavations especially on sloping sites....

AN INVESTIGATION INTO THE REMOVAL OF SEDIMENT .
The fixed experimental unit (installed at the Sand River intake) was successful in creating a crater at the raw water pumps intakes. Since the fixed unit used only about 15% of the raw water pump station's discharge and only intermittently when the removal of sediment was required, the operating cost of the fixed system was minimal....
