Most modern water-treatment plants now use rapid dual-media filters following coagulation and sedimentation. A dual-media filter consists of a layer of anthracite coal above a layer of fine sand. The upper layer of coal traps most of the large floc, and the finer sand grains in the lower layer trap smaller impurities. 5, record 1, English, - dual%2Dmedia%20filter

Un filtre à double couche (CAG [charbon actif en grains] et sable) est utilisé lorsque la réduction de la turbidité, ainsi que l'adsorption et l'élimination des contaminants sont regroupées dans un procédé faisant intervenir un seul appareil. Le filtre à double couche (habituellement situé après la sédimentation) sera probablement exposé à de plus fortes concentrations de COD [carbone organique dissous], et ce filtre sera épuisé plus rapidement. 5, record 1, French, - filtre%20%C3%A0%20double%20couche

Clogging, blocking and blinding. If the geotextile pore openings are slightly too small, then there will be insufficient initial wash-through of fine soil particles to promote the rapid formation of an efficient graded filter in the adjacent soil. Where the geotextile pore openings are even smaller, then there is a serious risk that either blinding, severe blocking or severe clogging will develop with time. Blocking is where soil particles resting on the surface of the geotextile, either totally or partially obstruct the pore openings.... Blinding is a special form of severe blocking, where the soil grading permits the suffusion of fine soil particles which are too large to pass through the geotextile.... Where the size of many of the soil particles is very close to that of the geotextile pore openings, then they are likely to enter the pores and become trapped within the geotextile. This can cause severe clogging which is most likely to arise in thick non-woven geotextiles with a complex pore structure. 3, record 11, English, - clogging

Le procédé le plus simple et le plus efficace consiste à installer sur les parois de la piscine des prises rapides sur lesquelles se branche le tuyau souple auto-flottant provenant du suceur. Les prises sont reliées à une tuyauterie de ceinturage du bassin, elle-même reliée à l'aspiration d'une pompe fixe équipée d'un préfiltre. Ce groupe électro-pompe doit être distinct des groupes de recirculation, incapables d'atteindre un vide suffisant pour la succion aisée des impuretés. On peut également utiliser un petit groupe moto-pompe mobile à essence, équipé d'un préfiltre auquel aboutit le tuyau souple du suceur. 1, record 30, French, - groupe%20de%20recirculation

The simplest and most effective method consists of installing(along the pool walls) rapid couplings to which the floating flexible hose from the suction head can be connected. The couplings are connected to a pipe running around the edge of the pool, and this pipe is itself connected to the suction inlet of a fixed pump fitted with a filter. This electric pump unit must be quite separate from the recirculation units which are incapable of creating a sufficient vacuum for easy suction of impurities. A small, mobile, petrol motor pump unit may also be used, fitted with a pre-filter to which the flexible suction hose is attached. 1, record 31, English, - suction%20inlet
