Patent DE-4101173-A1 (DE)
Title: Sepg. floating and sinking impurities from waste water
Inventor: BACHON ULRICH DIPL ING
IPC: B01D21/28
Filed: 1991-01-17
Abstract: A horizontal separation channel, in which the flow velocity is continuously reduced, is provided upstream of the main sedimentation channel of a device for treating waste water from food processing operations. In this separation channel, the warm water and floating impurities move upwards while the colder water and heavier impurities move downwards, and these layers of the water flow are guided into the corresponding regions of the main sedimentation channel. The separation channel is in the form of a conical pipe section, the cone angle for the colder lower flow layer being greater than that for the warmer upper flow layer. These layers may be separated from each other by guide vanes. The sedimentation channel takes the form of a body of water which rotates slowly about a vertical axis and into which the water flows tangentially at mid-height and at an equal velocity. The flow velocity in this channel is adjusted so that sufficient time is provided for the warm water to rise to the upper surface and the colder water to fall to the lower surface.
Patent DE-4115300-A1 (DE)
Inventor: MUELLER BERTHOLD
IPC: C02F3/20
Filed: 1991-05-10
Abstract: Porous or slotted hoses serve to introduce oxygen or oxygen-containing into water tanks of sewage treatment plants or into natural waters. When these hoses are installed in the form of heavy hose mats, these easily sink into the sludge, which impairs their function. If the hoses are mounted on frames, the forced circulation can be impaired especially in sewage treatment plants, which can cause sludge deposition. To avoid these disadvantages, the hoses (2) are laid in the troughs of a corrugated sheet (1). Rectangular troughs are preferred. <IMAGE>
