New Polymer Technology for Sand Control Treatments of …

All treatments were successful in stopping sand production. The first treatment lasted about four years, after which it had to be renewed. All other treatments show long-term efficiency. Only one well suffered from a loss in Gas Productivity Index (around 20%), for all the others, gas injectivity and productivity remained unaffected by the treatment. The well treated with microgel has been ...

OFFSHORE SAND CONTROL AND WELL STIMULATION …

Offshore, a form of sand control technology has been in commercial use since the early 1990’s. Sand control technology combines two mature oil and gas technologies, which has significantly improved well life, reliability, productivity and oil and natural gas recovery.1 In many offshore regions, the geologic formations that produce oil and gas are unconsolidated, which means the sand that ...

E21 - Treatment by slow sand filtration for use in the home

Sand filtration is frequently used in the treatment of groundwater to remove dissolved iron. Iron and manganese in the groundwater are oxidised by aeration and the flocs formed are subsequently trapped in the sand filter. After a certain period of time, the filter is saturated with particles and must be cleaned to prevent it from blocking up completely. Sand filters are cleaned by backwashing ...

3.1 Wastewater treatment technologies

Sand filters have been used for wastewater treatment purposes for at least a century in Latin America and the Caribbean. Two types of sand filters are commonly used: intermittent and recirculating. They differ mainly in the method of application of the wastewater. Intermittent filters are flooded with wastewater and then allowed to drain completely before the next application of wastewater. In ...

Sand filter - Wikipedia

Sand filters are used as a step in the water treatment process of water purification.. There are three main types; rapid (gravity) sand filters, upward flow sand filters and slow sand filters.All three methods are used extensively in the water industry throughout the world. The first two require the use of flocculant chemicals to work effectively while slow sand filters can produce very high ...

Handbook of Water and Wastewater Treatment …

Sand filtration is almost never applied as the primary treatment method. Most often, it is applied pretreatment or at the final stage; however, sometimes it is applied at the intermediate stage of water treatment. Sand filtration is most often used along with other filtration technologies—such as carbon adsorption, sedimentation and clarification, disinfection, and biological methods. The ...

Rapid Sand Filters | Water Treatment | Waste Water ...

Water Treatment filter media is most commonly sand, though other types of media can be used, usually in combination with sand. The sand used in rapid sand filters is coarser than the sand used in slow sand filters. This larger sand has larger pores which do not fill as quickly with particles removed from the water. Coarse sand also costs less and is more readily available than the finer sand ...

Tertiary Treatment - an overview | ScienceDirect Topics

A.J. Englande Jr., Peter A. Krenkel, in Encyclopedia of Physical Science and Technology (Third Edition), 2003 XII.A Suspended Solids Removal. Suspended solids removal in tertiary treatment implies the removal of those materials that have been carried over from a secondary clarification process. It is also employed as a pretreatment method prior to physical chemical treatment processes.

Components of a Complete Cleaning and Surface …

However, proper surface treatment is not a one-time thing; it must be a part of preventative maintenance and includes more than coating a mold’s surface in a hard metal for wear protection. When a mold is taken out of production because a part run is complete or has a maintenance issue, perform a complete mold cleaning and surface treatment program.
