An easily adaptable or do-it-yourself (DIY) installation water cleaning device on any existing spa or pool is provided herein. The cleaning device includes an electrolysis module equipped with a particular boron-doped diamond electrode on silicum substrate. The foregoing also relates to a method to clean water on spa or pools using a water cleaning device that includes particular boron-doped diamond electrode present on the elecrolysis module. The foregoing also relates to electrolyzed bathing water for use in the treatment of inflammatory diseases of the skin and for use for use in the treatment of wound healing of the skin.

Disclosed herein is a method for removing contaminants from an industrial fluid waste. The method comprises the steps of ozofractionating the industrial fluid waste whereby contaminants are oxidised and a foam fractionate is formed; and separating at least a portion of the foam fractionate and any precipitate from the ozofractionated fluid.

The present invention refers to an industrial process and system that is efficient and advantageous for inactivation of liquid wastes contaminated by mutagenic, genotoxic and/or teratogenic substances arising from high potency APIs production using inactivation chemical agents and excluding ozone, heat or UV light source.

A method and system of providing source water and managing produced/flowback water during a hydraulic fracturing process in an oil and gas operation. The process is an environmentally friendly method of reducing use of fresh water and recycles frac water. The net result is that a volume of frac water is properly managed. Thus, less reliance on transportation vehicles and trucks reduces costs as well as reduction of piping systems. It further reduces a threat of seismic events from disposing of produced water and flowback.

The present invention provides a kind of an integrated sewage treatment equipment for paper mill, which belongs to the technical field of sewage treatment, includes a box body, and the box body is arranged a water injection gap on the upper part at one side, the bottom of the box body is connected with a drainage pipe, and a filter assembly is arranged inside the box body movably, and the inner wall of the box body is equipped with a limit component which provides guidance for the movement of the filter assembly; the filter assembly includes several concentrically arranged annular plates, and two adjacent groups of annular plates are connected by a netting. The bottom of the annular plate is equipped with a chemical dosing component, and the inner side of the innermost annular plate is equipped with an adapter sleeve.

Methods and systems for converting ammonium waste streams into certifiably Organic ammonium salts having a variety of uses in greenhouse gas-reducing activities are herein described. The resulting ammonium salt compositions can be used to enhance crop yield.

The present invention relates to a method for recovering lithium from brine, and provides a method for recovering lithium from brine, the method comprising: (a) an impurity removal step of adding a carbonate supply source to brine including lithium, magnesium and calcium to precipitate and remove magnesium and calcium impurities; (b) a pH adjusting step of adding an acid to the brine from which the impurities have been removed, to adjust the pH of the brine; (c) a lithium-aluminum compound recovery step of adding an aluminum supply source to the pH-adjusted brine to recover a lithium-aluminum compound; (d) a lithium sulfate and aluminum oxide formation step of adding the lithium-aluminum compound to a sulfur supply source and calcining same to form lithium sulfate and aluminum oxide; and (e) a lithium sulfate solution yield step of selectively dissolving lithium sulfate from among the formed lithium sulfate and aluminum oxide to yield a lithium sulfate solution.

A publicly accessible urban beach entertainment complex is disclosed, with a man-made tropical, pristine-clear lagoon as the centerpiece of the complex, with surrounding entertainment, educational, sports, and commercial facilities, the complex having controlled public access and providing the look and feel of a tropical beach with clear waters and sandy beaches. In addition a method for efficiently utilizing facilities and land that are vacant, underutilized, have limited uses, or that are contiguous to or nearby recreational, educational, sports, or commercial venues is disclosed. The method providing a publicly accessible urban beach entertainment complex with a centerpiece man-made tropical-style pristine-clear lagoon. The method allows for generating revenue and increasing efficiency by pairing vacant sites, underutilized sites, limited use land, or sites that are contiguous to entertainment, educational, sports, and/or commercial venues with urban beach entertainment complexes. The complex preferably has a controlled public access, thereby allowing entrance upon payment of a fee.
