Abstract: Une membrane flexible à trous (10) s'étend sur un support bombé (11). Un tube central d'amenée de gaz (50, 82) se termine par des orifices de sortie (51) du gaz orientés de façon à diriger l'écoulement du gaz horizontalement dans l'espace (40) situé entre la membrane et le support, de manière que le gaz provenant de l'espace rempli d'air s'évacue par les trous (60) en fines bulles, et de telle façon que, lorsque l'alimentation du gaz s'arrête, la membrane se dégonfle et se replace en contact avec le support pour fermer hermétiquement tous les trous, ce qui limite l'obstruction. Cet appareil d'aération est utile dans l'oxygénation des eaux d'égout ou autres eaux usées, ainsi que des eaux de viviers d'anguilles ou autres poissons.

Abstract: A pump cylinder (18) is driven in reciprocation relative to a hollow piston (22) within the cylinder. The piston and cylinder each have valved inlet ports (33, 34; 43, 44) at each end. A tubular member (14) communicates with the hollow of the piston centrally between the piston ends and extends perpendicular to the piston, serving further as a stationary pivot for oscillation of the piston while the cylinder is driven in a swinging reciprocation relative to the piston. The tubular member extends through and works relative to a slot (19) formed through the cylinder wall so that reciprocation of the cylinder pumps a fluid along a flow path through the valved inlet ports and along said tubular member. The cylinder is driven at low speed by a motor (15) through a gear box (16) rigidly secured to a tubular frame (71) of the pump. A number of piston and cylinder devices may be driven by a common drive means, and employ a common tubular member, in a modular arrangement. The pump is simple, reliable and quiet, and is effective to provide small quantities of air at low pressure, e.g. for aeration at isolated effluent. treatment plants and at fish farms.
Abstract translation: 泵缸（18）相对于气缸内的中空活塞（22）往复运动。 活塞和气缸各自在每个端部具有阀门入口端口（33,34; 43,44）。 管状构件（14）在活塞端部之间中心地与活塞的中空部连通并垂直于活塞延伸，作为静止枢轴用于在活塞相对于活塞摆动往复运动的同时驱动活塞。 管状构件相对于通过气缸壁形成的狭槽（19）延伸并且工作，使得气缸的往复运动沿流动路径泵送通过阀门入口并沿着所述管状构件的流体。 气缸通过马达（15）以低速驱动，通过刚性地固定到泵的管状框架（71）的齿轮箱（16）。 许多活塞和气缸装置可以由共同的驱动装置驱动，并且以模块化的方式使用共同的管状构件。 该泵是简单，可靠和安静的，并且有效地在低压下提供少量的空气，例如， 用于在分离的污水处理厂和养鱼场进行曝气。

Abstract: A loose particulate material for use in waste water treatment comprises granules of plastics material carrying weighting material so that the granules have an average density of approximately 1.0 g/cc. At least a portion of the weighting material is carried within the granules and the surfaces of the granules are provided with concavities to provide a habitat for organisms effective in waste water treatment. The particles are manufactured by incorporating a weighting material into the granules, contacting the granules with grains of a soluble substance of an elevated temperature to coat the granules with the soluble substance grains and subsequently dissolving the soluble substance grains.

Abstract: A method and apparatus for coating granules of plastics material with a mixture of sand and salt grains comprises tumbling and heating a mixture of grains and plastics granules by passing them along a heated rotating hollow tube (1). The mixture of grains and plastics material granules are heated to a temperature not less than the softening temperature of the plastics granules so that the plastics granules become coated with the grains. The coated granules are then tumbled and cooled before leaving the rotating hollow tube.

Abstract: An apertured flexible membrane (10) extends over a domed support (11). A central gas supply tube (50, 82) terminates in gas outlets (51) oriented to direct the gas to flow horizontally into the space (40) between the membrane and the support to inflate the membrane away from the support so that gas from the inflated space discharges through the apertures (60) as fine bubbles and such that when the gas supply ceases the membrane collapses back into area contact with the support to seal all the apertures. This reduces clogging. The aerator is useful in the aeration of sewage or waste water and in fish or eel farms.

Abstract: Granules of plastics material have grains of an inert mineral such as sand coated thereon to provide a habitat for microorganisms effective in waste water treatment, the granules having a predetermined particle size range, and the grains having a predetermined particle size range and being disposed at a predetermined packing density range on the granules. The particles have an average density of approximately 1.0 g/cc such that a proportion tend to float and a proportion tend to sink in the waste water. The particles arc manufactured by contacting the granules of plastics material with a mixture of grains of the inert mineral and grains of a soluble substance such as salt, at an elevated temperature, to coat the granules with the mixture, and subsequently dissolving the soluble substance grains from the coating to provide the granules coated with the grains of inert mineral in the predetermined packing density range.

Abstract: Granules of plastics material are coated with a mixture of sand and salt grains by tumbling and heating a mixture of grains and plastics granules by passing them along a heated rotating hollow tube 1. The grains and plastics material granules are fed from hoppers 7,8, mixed by rib(s) 6 and heated to a temperature not less than the softening temperature of the plastics granules by a heater 5 . The coated granules are then tumbled and cooled before leaving the rotating hollow tube. The salt grains may then be removed by washing, to form a waste water treatment medium.

Abstract: A treatment vessel (50) contains a fluidizable bed (70) of loose particulate material comprising particles of sharp sand adhered to granules of polyethylene to provide a habitat for microorganisms effective in wastewater treatment. The material has a desired density slightly greater than 1.0 g/cc, a specific surface area in excess of 600 m /m , and a particule size range of about 3 mm to 10 mm. The bed and wastewater is fluidized and aerated by air bubbles emitted from self-sealing aerators (71) disposed at the base of the bed and arranged for placement and removal from above the water level. The loose material can rest directly on the aerator surface.
