摘要： The nozzle (20) comprises an housing (21) with an inlet (22) and an outlet (25) for the fluid to be treated, and a partializer (23) which is supported in elastically slidable and ad- 5 justable way. The head (29) of the partializer (23) is opposite the inlet (22) for the fluid to be treated and it is provided with grooves (39) which cooperate with grooves (40) realized in the peripheral edge of the said inlet (22) in order to produce a turbulent movement in the fluid to be treated. The partializing head (29) of the partializer (23) is moreover adapted to slide away from the said inlet (22) under the pressure of the liquid to be 0 treated, whenever the said grooves (39) and (40) need to be cleaned of clogging caused by solid particles contained in the liquid to be treated.

摘要： A process for the treatment of contaminated fluid and wastewater containing residuals from food processing and waste and residuals from animal feeding operations and effluent from the digestion of these residuals is disclosed. The process is carried out in an enclosed tank using a separation procedure that maintains the state of the separated solids in the same state as they were upon introduction to the system, i.e., aerobic, anaerobic or anoxic, based on the condition of the solids upon introduction to the system. The system utilizes rotary flow instead of rakes to harvest the solids from the effluent. The process has applications in the recovery of emulsion in wastewater treatment and the operation of digesters for re-feeding to the digester.

摘要： The aim of the invention is to provide a device and a method which makes it possible to filter fine and superfine particles from the dishwashing fluid of a dishwasher. This aim is attained by the device and method according to the invention for filtering particles from a dishwashing fluid of a dishwasher. The inventive device comprises a container (1) into which a predetermined quantity of a liquid (2) is introduced to which a foam-producing substance is added. The container comprises means (5) by means of which a gaseous fluid flows through the liquid to which the foam-producing substance is added, thereby producing a float (3) on the liquid to which the foam-producing substance is added. Said float has filtering properties so that a substantial part of the particles is filtered out in the float and remains in the float.

摘要： An improved production water treatment system and method are disclosed. The treatment apparatus includes a vertically oriented vessel (11) with tangentially disposed injection nozzles including one or more water input inlets (P 1 ,P 2 ) for the introduction of production water and one or more recycle fluid/sparge gas inlets (R 1 ,R 2 ,R 3 ,R 4 ) for the introduction of recycled water from the vessel (11) and a sparge gas. The tangential orientation of the injection nozzles creates a cyclonic flow within the vessel for improved sparge gas bubble/hydrocarbon contact. A hydrocarbon-rich layer migrates to the top surface (14) of the liquid in the vessel (11) where it is removed about a center axis of the vessel (11). The resulting hydrocarbon-lean production water has a sufficiently low hydrocarbon content that it is eligible for more intensive processing, such as with organophillic clay cartridges.

摘要： A flotation device for separating materials or mixtures of materials from suspensions includes a reaction and mixing space (18) with eccentric inlet (16) for the mixture of suspension particles with gas bubbles and for further transport into at least one centrally arranged vertical suspension distribution tube (26), wherein the suspension distribution tube (26) and the clarified fluid collecting tube (48) are arranged adjacently, the plates (30) surround the suspension distribution tube (26) and the clarified fluid collecting tube (48) in an annular manner; and every second annular plate space (31) between adjacent plates (30) is connected to the suspension distribution tube (26) and every other space (31) between plates is connected to the clarified fluid collecting tube (48), so that the flow takes place out of one space (31) between plates from the inside towards the outside to the separating space (32), and subsequently into an adjacent space (31) between plates from the outside towards the inside. The substantive advantages of the invention are in that by combination of the plate arrangement with the eccentrically loaded reaction and mixing space, improved flocculation and thus better processing values are obtained in the filtrate. Better separation values are obtained by separation using the double-plate principle.

摘要： The invention relates to a device and a method for chemically and physically separating solid materials from a suspension using flotation. A rotationally symmetrical flocculation/flow reactor (20) is provided with outlets in the lower part thereof and is arranged in a separating tank (12). At least one suspension inlet (24) extends eccentrically into said reactor. The supplied suspension is guided into the upper area of the flocculation reactor (20) via the suspension inlet (24). A circular flow is thus created which drains off from the flocculation reactor (20) downwards in a tangential and radial manner over the outer circumference into circularly arranged distribution cells (44) which reinforce the tangential component of the suspension flow when said flow is delivered into the separating tank (12). In prior art, the flow of the mixture consisting of the suspension and air-sacs extends radially outwards. One advantage of the invention is that said flow of the mixture has to travel a longer way to the outlets in the area of the wall of the tank due to the tangential flow component. The solid matter can be separated more effectively by virtue of the longer travel path or the longer presence in the separating tank.
