摘要： This invention relates to a novel intermittent slow sand filter and a method of using the intermittent filter. More particularly, this invention pertains to a novel slow sand filter which remains effective, even when intermittently operated, and which can be periodically cleaned without disturbing the action of the intermittent filter. A slow sand filter apparatus comprising: a container having an upper portion and a lower portion; a water inlet in the upper portion of the container, the water inlet being connected to a supply of water; a filter material filling at least the lower portion of the container, the filter material having a top surface below the water inlet; a schmutzdeuke layer on the top surface of the filter material; a water outlet in the lower portion of the container below the top surface of the filter material; and a water level maintenance device in the upper portion which maintains water in the upper portion of the container at a maintenance level above the top surface of the filter material, the maintenance level being a balance between (1) a water maintenance level that is sufficiently deep that water falling from the water inlet onto the top of the water in the container does not significantly disturb the schmutzdeuke layer; and (2) a water maintenance level that is sufficiently shallow that oxygen from the air above the water level can diffuse through the water and reach the schmutzdeuke layer so that the schmutzdeuke layer is maintained in living condition even when there is no flow of water through the water inlet.

摘要： A down-flow granular medium bed filter (10) is provided with at least one splash plate (20) for dissipating the force of influent liquid, the plate being mounted so as to be rotatable by lifting means (24,26) from a position parallel to the surface of the filter bed (14) to a position perpendicular to the bed surface when the liquid above the bed (14) rises to a selected first level (28). The splash plate (20) is maintained in the perpendicular position for the remainder of the filtration cycle, the backwash cycle and any chemical cleaning cycle, allowing unobstructed operation of the filter bed. The splash plate is returned to the original position parallel to the bed (14) at the start of another filtration cycle.

摘要： Apparatus for removing suspended particles from water comprises outer and inner concentrically arranged tanks and a carriage arranged on top of the outer tank for movement around the same. Unclarified water is introduced into the inner tank along with flocculating material for combining with the suspended particles in the water, and the mixture passes from the inner to the outer tank. Gaseous bubbles are introduced into the mixture for attaching to the flocculated suspended particles and floating them to the surface of the water in the outer tank, forming a sludge layer thereon. A scoop device mounted on the carriage removes the sludge for discharge from the apparatus. A plurality of filter beds are arranged near the bottom of the outer tank for removing the remaining precipitated flocs to complete the clarification of the water for discharge, and suction apparatus is arranged above the filter beds for cleaning the same. Timer means control the positioning of the suction apparatus over predetermined filter beds and the cleaning operation thereof.

摘要： Method and arrangement for filtering particles out of a liquid, in which the liquid containing particles is supplied to a sedimentation tank (12), and the liquid is made, by means of hydrostatic liquid pressure prevailing in the tank, to flow through a filter member (18) on the shell surface of a drum (14) mounted in the tank (12). When the liquid in the tank has risen to a predetermined level above the drum (14) as a result of clogging of the filter member (18), cleaning of the filter member (18) in situ in the tank is initiated.

摘要： A supply line (42) connects to a filter (13), and a delivery line (43) connects to the filter downstream thereof. Furthermore, a backwash line (44) and a discharge line (46) for discharging backwash water connect to the filter (13). In the operative condition, water is pumped from the supply line (42) via the filter (13) to the delivery line (43). In the backwash condition, water is pumped via the backwash line (44) and the filter (13) to the discharge line (46). By connecting a sensor (37, 41) for monitoring the pollution of the filter (13) to the control unit (29) and arranging it to backwash in dependence on signals received from the sensor (37, 41), unduly early or late backwashing of the filter can be prevented. There is further described a method for using the invention.

- à la surface du plan d'eau du bassin, un capteur (E1) de détection comprenant une électrode sensible à la présence ou à l'absence de liquide à un niveau de consigne prédéterminé, délivrant un signal représentatif du niveau de l'eau dans le bassin, et
- des moyens (8,100) de commande incrémentale de la vanne, fonctionnant en réponse au signal délivré par le capteur, propres à ouvrir la vanne par impulsions successives jusqu'à obtenir le dénoyage de l'électrode initialement noyée, ou à la refermer par impulsions successives jusqu'à obtenir le noyage de l'électrode initialement dénoyée, de manière à faire varier la perte de charge créée par la vanne en aval du bassin dans le sens contraire de la variation de perte de charge du lit filtrant concomitante à une variation du niveau de l'eau dans le bassin.
De la sorte, la vitesse de filtration de l'eau apportée dans le bassin demeure sensiblement constante.

摘要： A filter apparatus removes foreign substances contained in raw water by passing the raw water through a filter layer (8) made up of a particulate filter medium disposed in a filter tank (1). The apparatus is made up of: a partition wall (2) provided inside the filter tank (1) so as to extend from an upper end of the filter tank (1) downward while leaving a space to a bottom surface (7) of the filter tank (1) such that the filter tank (1) is divided into a supply portion (4) having a raw water supply port (3) and a discharge portion (6) having a backwashed water discharge port (5); wherein the bottom surface (7) of the filter tank (1) is inclined from the discharge portion (6) downward toward the supply portion (4), the bottom surface (7) having the filter medium spread thereon in a manner to cover both the supply portion (4) and the discharge portion (6), the filter medium being filled to such a depth that an upper end of the filter medium reaches at least a bottom end of the partition wall (2); water collecting pipe (10) embedded inside the filter medium for collecting filtered water; and backwashing device for backwashing the filter medium.
