Abstract: Intensive fish fattening in open waters is increasingly disturbed by deposits of harmful substances. Fish fattening in artificial ponds is uneconomic because of the considerable outlay in terms of the fresh water and area required. These disadvantages can be overcome by a specially designed fish tank and a new process for operating such fish tanks. The fish tank (10) has, in its longitudinal center axis, a pit (11), into which a filler (31) with vertically extending flow channels (37) is placed. The fish water, together with an air/oxygen mixture, is circulated through these flow channels approximately 30 times per hour. The fish water is purified (nitrified) biologically according to the adhesive activated-sludge process by micro-organisms adhering to the filler. 50 to 500 liters of fresh water per kg of growing fish are added to the fish water, depending on the type of fish.

Abstract: A diffuser for introducing gas in bubbles into liquid held in an aeration tank comprising a body member having a backing surface and passaging extending from a gas inlet to an outlet at the backing surface, and a flexible, gas permeable membrane covering the backing surface and secured at its periphery to the body member in sealing relationship thereto. The membrane is adapted to distend and move away from the backing surface upon delivery of gas under pressure to diffuser, with the gas flowing through the distended portion of the membrane and into the liquid in the form of relatively small gas bubbles, and adapted to collapse into engagement with the backing surface when gas under pressure is not delivered to the diffuser. A check valve comprising a movable valve member on the membrane and a valve seat on the backing surface enables flow of gas into the space between backing surface and the membrane, and blocks flow of liquid into the passaging in the body member.

Abstract: This specification describes a membrane aerated biofilm media and reactor (MABR) having a discontinuous layer of a porous material applied to the outer surface of a gas-transfer membrane. The porous material may have a void fraction of 50% or more. The porous material may have a thickness of up to about 500 microns and a pattern on the same order of magnitude as its thickness. The media may be used to carry on a deammonification reaction. In use, ammonia oxidizing bacteria (AOB) and annamox bacteria grown in or on the media, with the annamox bacteria located primarily in the porous material. The supply of oxygen through the gas-transfer membrane is limited to suppress the growth of nitrite oxidizing bacteria (NOB). Excess biofilm is removed, for example by coarse bubble scouring. The media may be placed in an anoxic zone of an activated sludge plant, which may be upstream of an aerobic zone.

Abstract: In a submerged membrane bioreactor (MBR or SMU), diffusers are used to eject air bubbles, primarily to facilitate the movement of mixed liquor past the membrane surfaces, cleaning and scouring the surfaces of the membranes with the mechanical energy of the combined air/liquid/solids movement. Oxygen transfer from the bubbles into the mixed liquor is often a secondary goal, for supplying oxygen to biological processes. The invention involves the use of a specific bubble diffuser, oriented at a selected upward angle, to enable a single style diffuser to accomplish simultaneous generation of mid-size and fine bubble aeration, with adjustment of the tilt angle varying the percentages of mid-size and fine bubble aeration. The angle selection, along with the number of diffusers and air volume selected, allows achievement of target liquid movement through the MBR.

Abstract: An aeration element for gasification or aeration of liquids includes an essentially flattened, rigid support element having a substantially oval cross-section and corrugated outer surfaces, the corrugated outer surfaces including ridges defining grooves therebetween; a threaded opening for receiving a cooperating fitting for connection to an air supply; and a flexible membrane of elastomeric material disposed around the support element. An assembly bracket includes upper and portions that can be cooperatingly attached to one another about the aeration element for securing the aeration element to a floor of a tank or pool. The assembly bracket includes through-going passages for enabling water to circulate around the bracket and reduce buoyancy of the assembly. Two aeration elements of shorter lengths can be positioned adjacent two one another, secured within assembly brackets, and connected at adjacent ends, so that one of the aeration elements functions as a conduit to the other aeration element when air is supplied into one of the aeration elements.
