Abstract: A self-contained, portable, waste water evaporating apparatus is shown. A solar-operated submersible pump pumps waste water from just under the surface of a waste water pit, through a pair of automatic backflushing filters and out misters located around the bank of the waste water pit. At a predetermined pressure across the automatic backflushing filters, the automatic backflushing filters are reverse cycled, one at a time, to backflushing particles back into the waste water pit. Periodically, the misters are purged and/or cleaned to remove particles therefrom. In response to sunlight, solar panels provide DC voltage directly to the submersible pump. If pressure from the submersible pump gets excessive, a pressure relief valve removes the excess pressure.

The method comprises a step of adding to the waste water a treating agent selected from a group of Al compound, Ca compound and mixture thereof at temperature of 50 to 300° C. for reaction, whereby boron trifluoride neutralized salt is decomposed to form Al salt or Ca salt of fluorine component so that the fluorine component is removed in the form of the Al salt or the Ca salt of fluorine component.

Abstract: A mobile flocculation and water treatment system includes at least one tank, preferably a series of adjoining tanks separated by weirs, and an adjacent pump house mounted on a mobile platform. At least one pump is mounted in the pump house. Fluid conduits run from the pumps to the tank. An overflow is mounted between the downstream tank and the pump house whereby fluid overflow from the tanks is directed into the pump house. The pump house provides a substantially water-tight reservoir zone to provide secondary containment. Water to be treated enters the upstream end of the tanks and is discharged from the downstream end.

Abstract: An agent and a method for dispersing spilled oil, particularly on a body of water. The compound is a viscous dispersant liquid comprising a mixture of surfactants and a viscosifying agent that may be stored, shipped, mixed, and delivered on site using standard equipment and methods. The compound is released as a cohesive, persistent, visible, gel-like or paste-like liquid that floats on water. At least one method includes delivering the viscous dispersant liquid onto an oil spill in a body of water utilizing a jet airplane flying at over about 100 feet and spraying the liquid in large, pea-sized droplets.

Abstract: A method and device for removal of solid contaminants from an air-containing, contaminated oil by leading the oil to the inlet of a filter separating the contaminated oil in a solid phase, which is retained by the filter, and a liquid phase, which passes the filter and leaves as a filtrate through the outlet of the filter. An increased pressure is added on the filtrate outlet. The filtration is more efficient as disturbing air bubbles are avoided.

Abstract: A fuel-filter abnormality detection device is used for a subject filter provided in a fuel supply device of an engine to filtrate a fuel. The fuel-filter abnormality detection device includes a first filter attachable downstream of the subject filter in fuel flow. A filtration capacity of the first filter is smaller than a filtration capacity of the subject filter, and the first filter traps a foreign matter on a downstream side of the subject filter to cause a change in fuel pressure indicating an abnormality of the subject filter. The fuel-filter abnormality detection device may include a bypass passage through which the fuel bypasses the first filter, a bypass control valve configured to allow the fuel to flow through the bypass passage when the abnormality of the subject filter is detected, and a second filter filtrating the fuel flowing through the bypass passage.

The body includes a chamber, a water tank for supplying water to the chamber, and a motor-driven impeller for generating an air flow over water stored in the chamber. An ultraviolet radiation emitting lamp irradiates water stored in the chamber. The air flow is humidified with water from the chamber, and conveyed to the nozzle for emission from the apparatus. A sensor detects the position of the nozzle relative to the body, and a drive circuit controls the actuation of the lamp depending on an output from the sensor.

Abstract: Chemical pretreatments are used to produce usable water by treating a water source with a chemical pretreatment that contains a hexavalent chromium and an acid to generate a treated water source, wherein the concentration of sulfate compounds in the acid is negligible, and wherein the treated water source remains substantially free of precipitates after the addition of the chemical pretreatment. Other methods include reducing the pH in urine to be distilled for potable water extraction by pretreating the urine before distillation with a pretreatment solution comprising one or more acid sources selected from a group consisting of phosphoric acid, hydrochloric acid, and nitric acid, wherein the urine remains substantially precipitate free after the addition of the pretreatment solution. Another method described comprises a process for reducing precipitation in urine to be processed for water extraction by mixing the urine with a pretreatment solution comprising hexavalent chromium compound and phosphoric acid.

Abstract: The present invention relates to filtration of liquids, such as water, containing substances that desirably should be removed from the liquids. The invention relates in particular to a filtration cake, being produced in situ of a cleaning system from substances that desirably should be filtered away. Particular preferred embodiments of the present invention relate to treatment of waste water, where an activated sludge is provided, which sludge contains activated sludge flocs. These flocs are accumulated on a fluid penetrable support structure to form a layer of flocs, which subsequently is compressed to form a filter of desired properties. The invention also relates to adapting waste water—or other liquids containing biodegradable substances—to optimized biodegradation and filtration by deflocculating flocs in an activated sludge during or before a biodegradation step and subsequently promoting re-flocculation prior to filtering or other means of biomass separation.

Abstract: A diffuser baffle for use in an in-line wastewater grease interceptor. The diffuser baffle lies within a grease collecting chamber between the inflow and outflow of a grease interceptor. The diffuser baffle has an open bottom which is sized and shaped respectively to fit into the grease collecting chamber. The diffuser baffle has an end operatively connected to the inflow opening to permit wastewater to flow into the body through the open bottom. The baffle has a downstream end which includes a deflector portion to deflect a wastewater stream in a direction generally into the grease collecting chamber. The body also includes a number of apertures to permit the deflected wastewater stream to pass through the baffle and into the grease collecting chamber, where FOG will separate before waste water exits the chamber through the outlet baffle.

Abstract: An apparatus for filtering water has a valve head and a filtration/purification canister removably mountable thereon. Connecting the canister to the valve head automatically opens a check valve in the valve head to permit water to flow from the valve head into and through the canister, and then back to and through the valve head to an outlet port. Disconnecting the canister from the valve head automatically closes the check valve, stopping the flow of water. A bypass valve is provided in the valve head to permit a sanitizing solution to flow through the valve head and along the lines of the water distribution system to sanitize the system, while bypassing the canister. The outlet port may be directly connected to an appliance that uses water, to eliminate possible contamination that may occur when water is brought indirectly from the outlet port to the appliance instead.
