    摘要: To provide a cleaning apparatus suitable for removing clogging substances trapped in a surface layer of a sand filtration layer. A cleaning apparatus equipped with drive wheels serving as a driving device configured to move across a surface of a sand filtration layer. A pump and a jet nozzle are provided as an agitation device configured to agitate a surface layer portion of the sand filtration layer only at a desired depth, and which blows the clogging substances upward into the seawater in a turbid water intake pit together with a filtration sand. A perforated pipe for suctioning turbid water, a pump, an ejector, and a discharge pipe for dilute turbid water are provided as a suction and discharge device configured to suction turbid water blown upward into seawater in the water intake pit by the agitation device, and discharge it to outside of the turbid water intake pit. Prevents clogging by performing a timely cleaning of the sand filtration layer, thereby making it possible to maintain a high-speed seawater infiltration rate for seawater. Impact on the surrounding environment is reduced, because the apparatus suctions turbid water containing clogging substances which is blown upward into the turbid water intake pit, and discharges it to outside of the system.

    摘要: Disclosed herein is a filter surface washer with 8 nozzles and 4 orifices for non-air-scouring of filter medium. The filter surface washer is conceptually original device for sand and dual media rapid filters by gravity. With this type of device, the surface of the filter bed should be washed effectively for a very short period of time. The filter surface washer is very effective for 1 m2 (null11.0 ft2) of filter area. For each surface washer are required 2.5-3 l/sec/m2 (3.5-4.3 gpm/ft2). The velocity of water jet in nozzle orifice should be 12-14 m/sec (39-46 ft/sec). The height of orifice of the nozzle (H0) from top of the filter surface should be 0.1-0.142 m. The values of velocity gradient will be 1000-1500 1/sec for diameter of nozzle's orifice d0null6 mm (nullnull), and for diameter of 4 orifices d0null0.003 m (nullnull), in lower part of the device. These values of velocity gradients should be realized when water level above the filter will be Hnull0.1-0.15 m, during the time of surface washing. On the upper layer of support gravel layers the velocity of water jet will be 0.25-0.275 m/sec (0.82-0.9 ft/sec) about 2-3 times lesser than permissible velocity. The time for surface washing alone is recommended 1-1.5 minutes, for concurrent wash 1-1.5 minutes, and next for backwashing alone 2-4 minute. Cleanliness of granular media will be guaranteed for a long period of time.

    摘要: A self-supporting modular underdrain member for use in a liquid filtration system comprises a main body or housing including a pair of longitudinally extending inclined walls which may have a pair of generally triangular transverse walls connecting the inclined walls to one another, the inclined walls each being provided with a pair of longitudinally extending recesses and a plurality of orifices communicating with each of the recesses. A pair of flanges are connected to the inclined walls for attaching the underdrain body to a floor surface so that the inclined walls, any transverse walls and the floor surface define a cross-sectionally triangular underdrain chamber. Two pairs of elongate cover plates are attached to the inclined walls over the recesses to form in each of the inclined walls a pair of longitudinally extending plenums for the equalization of backwash air and water flow. Each of the cover plates being provided with a plurality of spaced slots.
