A system and method for decontaminating a fluid and recovered vapor, particularly processing and recycling water used in an oil zone steam process, utilizing a vaporizer-desalination unit to separate a contaminated water flow into a contaminated disposal flow and a clean water vapor flow. The contaminated water flow is recovered after separation from a combined oil and water flow from an oil well. The clean water vapor flow is preferably passed through a steam generator to produce the steam used in the oil zone steam process. The steam is injected into the oil zone of a designated well and then extracted as the combined oil and water flow. Once primed with sufficient external water, the system and method is designed to operate continuously with minimal replenishment because of the water/vapor/steam cycle.

A process for decontaminating a fluid and recovered vapor, particularly processing and recycling contaminated water, utilizing a vaporizer-desalination unit to separate a contaminated water flow into a contaminated disposal flow and a clean water vapor flow. The contaminated disposal flow may be dried and separated into recovered minerals utilizing heat from the clean water vapor flow to dry the contaminated disposal flow.

Methods of making a powdered milk product are described. The methods may include providing an aqueous milk-sourced mixture, and evaporating water from the aqueous milk-sourced mixture to produce an evaporated milk-sourced mixture having a total solids concentration of 35 wt. % or more. The evaporated milk-sourced mixture may be dried to form the powdered milk product, which may have less than 6 wt. % water. Systems for making the milk powdered product are also described. The systems may include an evaporator to evaporate water from a supply of a milk-sourced mixture to form an evaporated milk-sourced mixture. They may also include a dryer to dry the evaporated milk-sourced mixture and atomize it into the powdered milk product.

A system and process for decontaminating a bio-contaminated wastewater fluid as from a slaughterhouse or similar facility. The system and process recovers purified vapor/steam through a decontamination unit having a plurality of alternating rotating trays and fixed baffles in a processing vessel producing separate purified and contaminant streams. One or more filter/strainer units are disposed in parallel before the decontamination unit, and may be used alternately while the other is cleaned. A rotating shaft connected to the rotating trays may also connected to an electrical generator to provide electricity for circuits and controls in the system.

The present invention relates to apparatus and methods of liquid purification and the subsequent production of useful by-products. A variety of liquids may be purified by the method and apparatus, including water and hydrocarbon mixtures/sludges. The method of treating waste products comprises the steps of adding an absorbent to the waste product to form a absorbed solid, semi-solid or fluid matrix, the matrix being then subjected to an increase in temperature. The apparatus comprises a material inlet, a heated generator tube, one or more outlets being connected with the heated generator tube, and a material outlet.
