Abstract:
The present invention relates to a system and a process of running the system that allows for the long term filtration of product without loss of filtration capability due to clogging or fouling. The system is a normal flow filtration system having one or more filter cartridges attached to an outlet of a housing in the system. The filter cartridge(s) are contained within a bowl and depend preferably vertically from the outlet. Liquid enters the bowl of the housing and contacts the outer surfaces of the one or more cartridges. Impurities are trapped on or in the surface of the filter and the filtered liquid flows through the filter and through the outlet. One or more parameters such as flow rate, transmembrane pressure drop and/or time are measured and when the desired parameter(s) are met, the filtration ceases. A backflushing occurs back through the filter cartridges so as to remove the trapped impurities on or in the filter surface. This backwashed material is directed to an outlet of the bowl that is connected to a drain. Additionally a port formed in the side of the housing adjacent an outer surface of the cartridge(s) can be used to provide a lateral washing of the filter surfaces. The system is then recirculated in a downstream manner to reestablish equilibrium and filtration is the restarted.
Abstract:
The LoweFlow Filter wastewater treatment system is a recirculating filtering system intended to treat typical residential septic tank effluent. Septic effluent is continuously (or near continuously) dosed under pressure to the treatment media through pressure compensating drip irrigation emitters.Wastewater trickles down through the media where it is attenuated through physical, chemical, and biological means. Treated wastewater or filtrate collected from the bottom of the recirculating filter returns to the recirculating tank, either by gravity flow or under pressure, through the flow splitter. During periods of low or no wastewater flow, a flow splitter will allow all of the filtrate from the treatment filter back into the recirculation tank. During periods of moderate or high wastewater flow, the flow splitter will allow all or a portion of the filtrate to be diverted for final disposal.

Abstract:
A mixing device for mixing air and water in a water purifier includes a water inlet pipe (2) and an air inlet pipe (3). The air inlet pipe (3) extends coaxially within the water inlet pipe (2) and defines therewith an annular gap (4) for providing an annular water jet. Downstream of the annular gap (4) there is provided a mixing member (6) for mixing water and air. The mixing member (6) includes a water flow disturbing device (7) which is provided to be hit by the annular water jet. At least those parts (2a) of the water inlet pipe (2) and/or those parts (3a) of the air inlet pipe (3) which define the annular gap (4), are made of plastic material. The water flow disturbing device (7) includes at least one helical member (8) which extends along the inner side of the mixing member (6) around through-flow portions (6a) thereof within the helical member (8) such that helical movements are imparted to the annular jet of water when it flows downwards through the through-flow portions (6a).
Abstract:
An apparatus for treating a liquid; such as water or a beverage, in order to improve the quality of the liquid, and in order to ensure that the minerals and nutrients which are naturally present in the liquid are assimilated in a living organism consuming the liquid to the maximum extent. At least two pipe segments are twisted about a common axis in such a manner that each of the pipe segments at least substantially abuts said common axis. Each pipe segment has an inlet opening and an outlet opening, and the pipe segments forms parallel flow paths between a common inlet and a common outlet. The liquid performs spiraling movements when flowing through the pipe segments, and thereby the minerals in the liquid are forced to be in a more absorbable form.
Abstract:
A method of and apparatus for treating liquids flowing in a thin film around a source of wave energy to directly expose the liquid to the wave energy, preferably generated in whole or part by an electrical arc between carbon electrodes. In addition to the wave energy generated by the electrical arc, energy generated by cavitation of the flowing liquid may be used in treating the liquid.

A protein skimmer having a water column chamber and a fixed deflector. The fixed deflector including a plurality of blades that impart a swirling action on water flowing through the deflector. The deflector further providing an even distribution of bubbles within the water column chamber during protein filtering operation. The deflector including a central hub that aids in maintaining the velocity of water flowing through the deflector.
Abstract:
A rotating annular crossflow filter shears radially outward flowing axial feed between counter-rotating coaxial centrifugal impellers. A radial impedance of flow at the impeller periphery slows the radially outward flow and increases residence time of feed between the impellers. Shear lift ejects solids from the boundary layer at the filter surface, and ejected solids collect by centrifugation at the impeller periphery, where they thicken into a sludge and are extruded. Gases, oils, floating solids, and fractions having a specific gravity less than water evolve into radial vortices and are sucked radially inward and out from between the impellers by an axial pump. Three way phase separation proceeds continuously in one pass through a simple mechanical device having a long residence time for feed in the processing zone.Opposing rugose portions of counter-rotating impeller surfaces cause audio frequency pressure pulses. At the impeller periphery, the pressure pulses milk liquid out of sludge. At the portion of the radial passage prior to the filter, pressure pulses evolve gases and degassed cavitation bubbles inactivate microbes. Degassing of the high energy forced periodic cavitation bubbles between the impellers removes the cushion of noncondensibles which would otherwise absorb energy on compression, therefore implosion becomes extremely violent and a barrage of high pressure pulses and ultraviolet light pulses inactivates microbes.Applications include field water purification, municipal and industrial wastewater degassing and sludge thickening, swimming pool filtration, effluent dewatering, wine and beverage degassing and clarification, fruit crushing, olive oil dewatering, produced brine and drilling mud processing, manure slurry dewatering and degassing, and recovery of solvents and fine suspended solids from fluid mixtures such as wastewater from machining operations.
