This invention relates to a “high lower alcohol content” (>40% v / v of a C1-4 alcohol) liquid composition able to be dispensed as a stable foam with the use of non-propellant foam dispensing devices from non-pressurized containers The liquid compositions comprise an alcohol, C1-4 (>40% v / v), a silicone-based surfactant of at least 0.001% by weight to prepare a foamable composition, 0-10% w / w of additional minor components added to obtain the desired performance (a foamable composition), and the balance being purified water. The compositions may include emulsifier-emollients and mosturizers, secondary surfactants, foam stabilizers, fragrances, antimicrobial agents, other type of medicinal ingredients, and the like ingredients or additives or combinations thereof commonly added to alcohol gels or foams, aerosol compositions or to toiletries, cosmetics, pharmaceuticals and the like.

An apparatus for purifying water, such as for desalinization, includes a source of a heated air stream, the heated air stream having a temperature above an ambient temperature. A diffusion tower having high surface area material therein receives a water stream including at least one impurity and creates at least one region having thin films of water therein from the water stream. The heated air stream is directed over the thin films of water to create a humidified air stream that is at least substantially saturated. At least one direct contact condenser is in fluid communication with the humidified air stream for condensing the humidified air stream, thus producing purified water. A power plant can include the apparatus for purifying water, where energy to heat the air stream is provided by low pressure condensing steam.

The invention discloses a method for extracting cannabidiol from cannabis. The method comprises the following steps: smashing and drying extraction fractions of cannabis to obtain medicine material powder; extracting the medicine material powder with 30% to 100% (V / V) of ethanol to obtain an extracting solution; concentrating the extracting solution to obtain an extract; carrying out water precipitation on the extract, and removing impurities to obtain a water precipitation solution; centrifuging the water precipitation solution and adding 10% to 100% (V / V) of ethanol into an obtained precipitate, and dissolving the precipitate to obtain an alcoholic solution of the precipitate; carrying out column chromatography on the alcoholic solution of the precipitate; eluting an obtained eluant after the concentration column chromatography, and adding ethanol for supersaturated dissolution to obtain a crystal substance; adding the crystal substance into purified water or ethanol for washing to obtain a primary product; blending the primary product with purified water, and drying to obtain the cannabidiol. Only highly safe ethanol is adopted as a solvent, the purity of the cannabidiol in a finished product is improved, and the psychotoxic component of tetrahydrocannabinol is also removed, so that the product safety is improved, and the method is applicable for industrial production.

This invention relates to methods of diluting hypochlorite and hypochlorous acid compositions with purified water to produce stable compositions. These compositions can be used to treat allergen containing surfaces, hard surfaces, food contact surfaces, hospital surfaces, food surfaces, kitchen surfaces, bathroom surfaces, human surfaces, animal surfaces, military equipment, transportation equipment, children's items, plant surfaces, seeds, outdoor surfaces, soft surfaces, air, wounds, and medical instruments.

A method of water purification including the steps of passing source water through at least one reverse osmosis unit to produce a product water and reject water, directing the product water from a reverse osmosis unit into the dilution stream of a continuous electrodeionization unit, directing the reject water from the first pass reverse osmosis unit through a softening unit to produce softening unit output water with fewer hardness elements than the reject water from the first pass reverse osmosis unit, directing the softening unit output water into a concentrate stream of the continuous electrodeionization unit, and wherein the continuous electrodeionization unit further purifies the water from the dilution stream to produce purified water.

Systems, methods, and devices for preparation of purified water and medicaments for various uses including blood treatment are described. Methods, devices, and systems for creating multiple-treatment batches are described.
