Abstract: A water recovery method and apparatus which uses a desiccant, such as lithium chloride, to recover water vapor from the engine exhaust of a vehicle. The apparatus uses liquid-contactor to transfer water vapor from the vehicle exhaust to the liquid desiccant. The desiccant is then transferred to a reverse osmosis system which separates the liquid desiccant into potable water and a concentrated desiccant.

Abstract: A method and apparatus for desalinating seawater which uses an ammonia bicarbonate forward osmosis desalination process. Seawater is pumped through one side of a membrane assembly. A draw solution is pumped through the other side of the membrane assembly. The draw solution withdraws water molecules from the seawater through the membrane into the draw solution. A draw solution separator receives a heated draw solution which then decomposes into ammonia, carbon dioxide and water. Potable water is separated from ammonia has and carbon dioxide gas. The ammonia gas and carbon dioxide gas are recombined with a portion of the potable water stream to reform the ammonium bicarbonate draw solution.

Abstract: A treatment facility for removing toxic metals from storm water runoff to provide clean water. The treatment facility includes a pretreatment chamber for removing large toxic particles from the storm water runoff and absorbent chamber for removing fine particles of toxic metals from the storm water runoff. The absorption chamber has an absorption bed of three absorptive materials for removing the fine particles of toxic metals from the storm water runoff.

Abstract: A method for detecting change in the foam forming characteristic of an input stream of an aqueous solution which continuously samples the input stream by taking a series of discrete, independent measurements. The method relies on an acoustic sensor to measure foam height within a column. A sample of the input stream is introduced into the column, and aerated to produce foam. The height of the column of foam is then measured using the acoustic sensor, which is correlated with the concentration of foam forming chemical.

Abstract: An apparatus for detecting change in the foam forming characteristic of an input stream of an aqueous solution which continuously samples the input stream by taking a series of discrete, independent measurements. A sample of the input stream is collected, analyzed, then discarded. The collect-analyze-discard cycle is repeated. The apparatus relies on an acoustic sensor to measure foam height within a column. This allows the column containing the foam to be fabricated from any material, including durable plastics. A sample of the input stream is introduced into the apparatus. The sample is then aerated by a aeration stone to produce foam. The height of the column of foam produced is then measured using the acoustic sensor. The sample is then discarded and the process repeated. The height of the foam column is correlated with the concentration of foam forming chemical.
