The invention relates to compositions for treating and ameliorating skin conditions including acne, rosacea and wrinkling caused by photodamage or conditions related to aging, hormonal imbalances, hyper-pigmentation, melasma, keratosis or the like. The invention can also be used to treat conditions of the scalp such as dandruff. The present invention also relates to compositions that can be used to remove biofilms from contact lenses. More particularly, this invention relates to a composition comprising (a) one or more metasilicate; (b) one or more carbonate; (c) one or more glyconate; and (d) one or more sulfate. The composition may also contain (e) salts, e.g., sea salts and other additives or active agents.

A method and device for the chemical conversion, filtration and / or purification of fluids water or other solutions containing microbiological and chemical contaminants, such as fluids containing arsenic, chlorine, bacteria, viruses, and cysts, where the fluid is passed through a purification material composed of fluid treatment carbon, metal phosphates, metal oxides, reduced metals, metal silicates, metal sulfates, metal carbonates, metal hydroxides, or combinations thereof. The material may be included in a fixed binder matrix.

The invention discloses a process to implement and maintain water bodies larger than 15,000 m3 for recreational use, such as lakes or artificial lagoons, with excellent color, transparency and cleanness properties at low cost, which comprises the following steps:a.—providing a structure able to contain a large water body larger than 15,000 m3;b.—feeding the structure of step (a) with inlet water having iron and manganese levels lower than 1.5 ppm and turbidity lower than 5 NTU;c.—measuring water pH, ideally it should be within a range lower than 7.8;d.—adding an oxidizing agent to the water contained in the structure of step (a), with which a 600 mV minimal ORP is controlled in water for a minimal period of 4 hours and in maximal cycles of 48 hours;e.—adding a flocculating agent in concentrations within 0.02 and 1 ppm with maximal frequencies of 6 days and cleaning the bottom of the structure of step (a) with a suction device to remove precipitated impurities from the bottom of said structure, together with the additional flocculants and;f.—generating a displacement of surface water containing impurities and surface oils by means of the injection of inlet water according to step (b), which generates said displacement in such a way to remove said surface water by means of a system for impurities and surface oils removal arranged in the structure of step (a), which together with step (e) replaces traditional filtering.The present invention also discloses a structure to contain large water bodies comprising a system for the removal of impurities and surface oils by means of skimmers and the suction device to clean said structure.

A method and device for the filtration and / or purification of fluids water or other solutions containing microbiological and chemical contaminants, such as fluids containing cysts, bacteria and / or viruses, and heavy metals and / or pesticides, where the fluid is passed through a purification material composed of magnesium containing mineral and more preferably silicates containing magnesium, oxides containing magnesium, hydroxides containing magnesium, and phosphates containing magnesium and absorption media in a fixed binder matrix.

Presented is a liquid filtering apparatus and method that overcomes the disadvantages encountered with prior bed filtration systems by providing a filtering apparatus that incorporates a super-buoyant filter medium having a specific gravity very substantially lower than that of the process liquid being filtered. This feature enables a majority of the medium to float on top of the process liquid. Due to the significant differences in specific gravity between the media and the process liquid, super-buoyant media produce a highly advantageous means of naturally, gravimetrically separating both clean and contaminated filter media and process liquid into separate “phases”. Under normal filtering operation, the filter media is contained within a filter housing by a bed support near the top of the filter housing, and particulate material is filtered from a process liquid that passes through the housing. To regenerate the filter media, the housing is drained and a nozzle creates a backwash spray that washes the particulate material from the filter media. During the backwash process, the filter media rises past the nozzle as the level of the backwash liquid in the housing rises, so that the entire filter media is regenerated.

The invention relates to a method for purifying water by forming in an electrolytic cell molecular halogen, hypohalic acid, hypohalite ions or combinations thereof, from halide ions dissolved in the water; and dissolving one or more soluble metal salts in the water to provide corresponding metal ions. The invention also relates to a system for purifying water, having an electrolytic cell comprising a plurality of electrodes sufficient to electrolytically convert halide ion in the water into molecular halogen, hypohalic acid, or hypohalite ions, or combinations thereof; and a metal generator, which provides concentrations of one or more metals to the water.

An apparatus and method are for disinfection and purification of a liquid, gaseous or solid phase, or a mixture thereof. The apparatus includes: a central electrode, a dielectric layer adjacent to the electrode, a first area adjacent to the dielectric layer, and is configured to introduce a first medium into the first area, a second area adjacent to the first area. The apparatus is also configured to introduce a second medium into the second area, and for creating a plasma in the first medium, while the first medium is present in the first area, by applying a voltage between the first electrode and a second electrode. An injector injects the plasma into the second area, in order to be mixed with the second medium.

Systems for controlling aspects of recreational or other environments are described. Such systems are especially, but not exclusively, useful for controlling either or both of pool or spa settings and operations and include equipment that may be connected, in any appropriate way, to personal or other computers or other components capable of accepting and processing input. Operations of the systems additionally are capable of being simulated through software.

An oxidizing agent comprising a pre-measured amount of stabilized potassium hydrogen peroxymonosulfate and a buffer in a sealed water-soluble pouch, said pouch comprising a hydrolyzed copolymer of vinyl acetate and at least one of acrylic acid, methacrylic acid, maleic acid, itaconic acid, and esters thereof is disclosed.

The present invention relates generally to stable percarboxylic acid compositions comprising, inter alia, at least two stabilizing agents, and various uses for water treatments, including water treatments in connection with oil- and gas-field operations. The present invention also relates to slick water compositions and gel based compositions that comprise stable percarboxylic acid compositions and the use thereof in oil- and gas-field operations.

A filter for a spa or pool, having a filter body which receives a filter bag having a sheath encompassing the exterior of the filter body and a pocket extending inwardly from the front end of the sheath into the filter. Operation of the spa water circulation system draws spa water into the filter bag pocket while concurrently spa water is drawn transversely through the filter bag sheath and auxiliary spa water openings into the filter body. An O-ring encircles the upper portion of the filter bag to releasably retain such bag to the filter body during operation of the spa water circulation system.

The present invention is further directed to a pump and filter assembly that can be positioned at any depth within the water being filtered and can be easily removed after the desired filtration is complete. The present invention is further directed to a solar powered portable pump and filter assembly that operates while floating on fluid being filtered. The present invention is further directed to a highly efficient portable pump and filter assembly that is adapted to be directly coupled to and powered by various power sources including direct current and green energy supplies such as solar or wind power.
