  • Patent number: 9353713
    Abstract: A fuel water separator (FWS) filter that is configured to permit water to be drained from the water sump of the FWS filter without shutting off fuel flow to the FWS filter. A check valve is positioned between the water sump and the filter element. When the FWS filter is under vacuum (e.g. as in operation), the check valve can be closed to allow water to drain from the sump. The check valve can close automatically by floating on accumulated water in the sump until the water rises to a level where the check valve is closed. The check valve can also close by opening the drain valve of the FWS filter, which causes a differential pressure between the sump and the vacuum created in the filter element chamber, which forces the check valve to close.

  • Patent number: 8691089
    Abstract: The disclosure relates to a separation process. An aerated inlet mixture of fluid and solids is fed to a flotation separation vessel and is separated into an upper float layer and a lower clarified layer. The upper float layer is withdrawn from the vessel when the height of the upper float layer exceeds the height of an overflow conduit and forms a concentrated solids effluent. The lower clarified layer is withdrawn from the separation vessel as a clarified fluid effluent. The separation process is performed continuously using a control process that maintains a relatively stable distribution between the lower clarified layer and the upper float layer. The control process is a closed loop process that monitors the instantaneous height of the vessel contents and computes an error function based on the instantaneous height and a set-point height. The error function is used to periodically adjust the outlet flowrate of the clarified fluid effluent. The resulting process has improved stability (e.g.

  • Publication number: 20120097607
    Abstract: Waste water conditioning has nearly 150 years of history. During this time, a method has developed that is considered to be state of the art. While this method meets the requirements at hand, it is complicated and expensive. The novel method breaks down the rigidly entrenched method and simplifies it. In a plurality of stages, the only energy that is used is gravity, which is readily available and free of cost. Thus, an “alternative sewage treatment plant” has been developed, which has a simpler method and is less expensive in terms of investment costs and operating costs, at the same capacity, and requires only a fraction of the previous required surface area. The most important characteristic of the invention is that the novel method separates solids from waste water immediately after entering the sewage treatment plant. Mechanically purified water is much faster, easier and less expensive to purify. The paths pursued for conditioning of the sludge are also new.

  • Patent number: 6207045
    Abstract: An integrated control module for connection to a fuel-water separator for controlling the drainage of water from the fuel-water separator includes a water-in-fuel sensor having a pair of spaced-apart probes, a drain valve whose open or closed condition is controlled by a solenoid, an electrical connector for receiving input power and a control circuit arranged with first and second circuit portions which cooperate so as to control the energizing of the solenoid and thus the opening or closing of the drain valve based on the resistance between the pair of spaced-apart probes. The integrated control module is designed to attach to either a sidewall or a base of the fuel-water separator so that the probes extend into the interior of the fuel-water separator into a region where separated water accumulates. The resistance between the probes is then used as a means for sensing an average probe voltage which in turn determines the state of the solenoid.

  • Patent number: 5935427
    Abstract: The present invention relates to a system which makes it possible to remove undesirable liquids, generally an aqueous phase, which precipitate to the bottom of tanks for storing liquid products. Use is made of a drainage device (30) which comprises a concave body (31), a seat (26), and an interface float (8) which has a plug portion (25). This interface float (8) is designed to sink into the product and to float on the aqueous phase. As the level of the aqueous phase drops, the plug portion (25) settles sealingly on the seat (26), halting the drainage operation since all the accumulated aqueous phase has already been drained off. The drainage system may be automatic or manual. In the former case, use is made of a sensor (12) for detecting the presence of an aqueous phase and commanding the process of opening a shut-off valve (11) and allowing drainage of the accumulated aqueous phase.

  • Patent number: 5879543
    Abstract: An environmentally safe and compatible filter and dehydrator apparatus for dehydrating and filtering impurities from fuel materials having a filter housing, a filter element composed of non-metallic, environmentally safe material and a water sensor used to detect the presence of water and generate a signal in response thereto to automatically engage a pump to remove a quantity of separated water from the filter housing, in the absence of allowing air to enter the filter housing. While processing fuel through the filter housing, a natural fuel/water contact forms within a lower portion of the filter housing. As fuel material is filtered and the fuel/water contact rises within the filter housing, the fuel/water contact approaches the water sensor. When the water sensing means detects the presence of water, the water sensor generates a signal to engage a pump to remove a quantity of separated water from a lower opening in the lower portion of the filter housing.

  • Patent number: 5855793
    Abstract: The invention relates to the treatment of waste water containing a harmful ion such as a heavy metal ion or fluorine ion by the coagulating sedimentation method using an inorganic coagulant such as an iron compound or an aluminum compound. After separating treated water from the sediment (sludge) in which the harmful ion is incorporated in insoluble form, the pH of a mixture of the sediment and water is suitably adjusted to cause elution of the harmful ion from the sediment. Then the sediment is separated from the eluate and reused as an inorganic coagulant. By reusing the sediment in this manner, the waste water treatment is accomplished without producing a large quantity of sludge and the consumption of inorganic coagulant and auxiliary chemicals can be greatly reduced, while the concentration of the harmful ion in the treated water becomes sufficiently low.

  • Patent number: 5118408
    Abstract: An aperature is formed in the bottom wall of the launder. A downwardly extending container communicates with the aperture. A weir is positioned immediately downstream of the aperture. The container and weir combine to form a separator. In the launder, free water and solids contaminants settle and form a bottom layer of dirty water. The layer is diverted into the container through the aperture and the weir temporarily retains a small head of it. Temporary retention in the separator therefore generates a vertical fluid column comprising an upper layer of relatively clean froth and a lower layer of dirty water, said layers having an ascertainable interface. The elevation of the interface is monitored and contaminated fluid is withdrawn from the container as underflow at a rate controlled to keep the interface elevation substantially constant. The froth overflowing the weir is reduced in water and solids relative to the original froth issuing from the flotation vessel.
