Abstract: A curb inlet filter adapted to work in conjunction with a curb inlet comprised of permeable filter fabric fashioned generally in a V cross section, comprising an upper and lower fabric layer separated by one or more gussets. A user inserts the curb inlet filter into a curb inlet and may apply pressure to push the filter into the curb inlet causing the gussets to compress as the invention enters the curb inlet and resulting in a press fit between the gussets supporting the upper and lower permeable filter fabric layers. The compression fit retains the inlet filter into place and the curb inlet. Water may pass through the permeable filter fabric, while the permeable filter fabric prevents sediment and other unwanted debris from entering the storm water drainage system.

Abstract: A method and apparatuses are presented for rejuvenating a bed of granular filter medium that has accumulated contaminants during filtration of a liquid stream. The method first includes the step of establishing a small volumetric flow rate of clean filtrate in reverse flow. Then, the filter media is agitated to break-up contaminants that have become agglomerated on the surface of or within the interstitial spaces of the filter media.

The jetting stream is dispersed throughout the filter media through a plurality of radial nozzles located within the filter bed. The radial nozzles disperse the gas within the liquid and filter media causing sufficient turbulence and agitation of the filter media granules to liberate the trapped contaminants without the need for high liquid flow rates.

Abstract: When producing biodiesel from fats, oils or split fatty acids rich in steryl glycosides, the light phase rich in fatty acid alkyl esters, which is obtained from the transesterification or esterification, is washed with water in a washing column, wherein the suspension layer formed is treated by stirring. In this way, the steryl glycosides are transferred into the light phase of the wash. In a subsequent treatment of the light washer phase with water in an intensive mixer, compact steryl glycoside/fatty acid alkyl ester/water agglomerates are obtained, which can easily be separated by means of centrifugation. From the light phase of centrifugation, on-spec biodiesel is obtained upon further processing by drying and/or filtration. This process is suitable for processing fats, oils or split fatty acids with a high content of steryl glycosides and avoids the use of auxiliary substances foreign to the process. It is characterized by simplicity of equipment and a low demand for energy.

Abstract: An energy efficient desalination process that does not produce waste products involves the extraction of water from a first solution, such as seawater, by using a second concentrated solution to draw the water from the first solution across a semi-permeable membrane. By manipulating the equilibrium of the soluble and insoluble species of solute within the second solution in favor of the soluble species of the solute, a saturated second solution can be used to generate osmotic pressure on the first solution. Also, by adjusting the equilibrium in favor of the less soluble species after the water has been drawn from the first solution, a portion of the solute can easily be precipitated out. Heating the second solution decomposes the solute into its constituent gasses. The constituent gasses and precipitated solute may be recycled through the process to affect the changes in equilibrium and eliminate waste products.
