In some implementations, a method may include introducing into a contaminated media a suspension of a bioremediation composition. In addition, the method may include where the bioremediation composition may include a first bioremediation composition having a first blend of one or more electrolyte solutions capable of ionic conduction and a second bioremediation composition having a second blend of one or more active materials and being capable of electric conduction.

Method of removing of per- and polyfluoroalkyl substances (PFAS) from water are described. The methods involve sparging a gas into a container of water; and collecting an aerosol released in a volume above the water.

A mobile sewage treatment and water reclamation system for rapid deployment to augment existing wastewater systems and/or provide interim service in lieu of permanent facilities, includes: (a) a denaturing stage wherein raw sewage is first ground into suspendable grit, its pH lowered to kill acid-sensitive bio-organisms and raised to kill base-sensitive bio-organisms, and then neutralized; (b) a clarifying stage employing an inverted-cone tank to circulate the solution after injection with chemicals to flocculate small particles for collection in a layer for siphoning off; and (c) a disposal stage wherein clarified water passes through media filters to remove remaining solids and odors, the effluent water being clean enough for irrigation, aquatic life and discharge into waterways; and wherein sterile sludge is pressed into semi-dry solids, then dried, crushed, powdered and bagged for use as high-nitrate biomass fertilizer or for fossil-fuel power co-generation applications.

The present invention relates to compositions and methods for the remediation of contaminated solids and liquids. In particular, embodiments of the present invention relate to the bioremediation of solids and liquids by a composition comprising a biocatalyst or mixture of biocatalysts. The present invention also relates to methods for producing the bioremediation compositions and methods for applying the bioremediation compositions to contaminated sites, including treatment, storage, and disposal facilities, as well as various contaminated water sources, such as aquifers and reservoirs.

A method of purifying water polluted with one or more organic compounds, includes adding a peroxide source to the polluted water in an alkaline environment in the presence of at least one additive selected from the group consisting of surfactants and phase transfer catalysts, optionally feeding oxygen or an oxygen-releasing substance to the water, separating the so-formed reaction mixture into aqueous and organic phases, to recover a treated water stream by an organic stream, wherein the purification of the water by the removal of organic pollutants is achieved at ambient temperature. The method can also be used for disinfection of water polluted with microbial pollutants.

Various aspects of this disclosure relate to toilet systems that include compositions to inhibit wastewater from freezing in a waste tank of a toilet. A first fluid treatment composition comprises a salt that is introduced into the waste tank. A second fluid treatment composition is a solid composite that also comprises a salt and that is introduced into a urinal in fluid communication with the waste tank.

The present invention provides a process for the treatment of sewage sludge with enzymes, which process comprises treating a sewage sludge resulting from the treatment of municipal or industrial waste water with a composition comprising a fermentation supernatant product from a Saccharomyces cerevisiae culture and a non-ionic surfactant, wherein said fermentation supernatant product is free of active enzymes, at conditions suitable for generating said active enzymes from said sewage sludge in situ.

A disinfection apparatus and method is provided for disinfecting a fluid. The apparatus elements define three internal container volumes. Fluid is introduced into an entry volume where its flow is conditioned to reduce splash and slow the fluid flow. The fluid is then channeled into a disinfection volume where a disinfection unit delivers a disinfection agent to the fluid. Finally, the fluid exits the apparatus through an exit volume. In one aspect, a sink-trap is disclosed in which wastewater liquid contacts a pair of diverters. The diverters have conditioned contact surfaces that slows and spreads the liquid flow and reduces liquid splash. The wastewater then passes through a UV chamber in which it is disinfected. The liquid then exits the sink-trap. Advanced self-cleaning apparatus are additionally disclosed to clean and disinfect the sink-trap and trapped wastewater. The entire apparatus operates under computer control.

Some implementations of the present disclosure prevent, reduce or at least slow equipment fouling using passivation as a treatment prior to contacting metallic components with hydrocarbon containing fluid, that is, an environment where fouling occurs. For example, one implementation includes a method of passivating heat exchangers in a SAGD process or system using the compositions and compounds of the present disclosure. The composition may be applied to a component prior to its first inclusion in an online system or following placing the system offline for maintenance. The composition may be used to treat metallic equipment surface(s), for example, via contacting them with a suspension or solution of the composition described herein, prior placing the system online. The method may further include treatment of the process fluid, for example, via injection or batch treatment of the composition with the compositions described herein into the process fluid.

The invention concerns a flocculation formulation. The invention also concerns the treatment of mine tailings in the form of aqueous effluents comprising solid particles. With the method of the invention, it is possible to separate all or part of the water from an aqueous effluent comprising solid particles.
