A catalyst for wastewater treatment is disclosed. The catalyst includes a porous carrier, iron oxide impregnated into the pores of the porous carrier, and platinum impregnated into the pores and mixed with the iron oxide in the pores. Also disclosed are a method for preparing the catalyst and a method for wastewater treatment using the catalyst.

Materials for binding per- and polyfluoroalkyl substances (PFAS) are disclosed. A fluidic device comprising the materials for detection and quantification of PFAS in a sample is disclosed. The fluidic device may be configured for multiplexed analyses. Also disclosed are methods for sorbing and remediating PFAS in a sample. The sample may be groundwater containing, or suspected of containing, one or more PFAS.

The present invention relates to a method for treating wastewater containing a furan compound, a microbial preparation for use in the method, a method for high density culture of a microorganism for use in the above method, and a method for producing a microbial preparation by using the culture method.

A stabilized, gas-infused liquids containing ultra high concentrations of infused gas, produced by: generating a gas-infused liquid in a sealed vessel under a high pressure of at least 20 psi; stabilizing the gas-infused liquid by passing the liquid while still under the high pressure through a tubular flow path arrangement which compresses the infused gas into nano bubbles in the liquid; infusing an additional amount of the gas into the stabilized liquid by injecting the same, while still under high pressure, back into the sealed pressure vessel along with more of the gas; and again stabilizing the liquid by again passing liquid, while still under the high pressure, through the tubular flow path arrangement to thereby form the additional amount of infused gas into nano bubbles in the liquid.

A method of controlling a volatile fatty acid in an aqueous industrial system is provided in the present disclosure. The method includes determining a level of dissolved oxygen in process water in the aqueous industrial system and adding an effective amount of a control agent to the process water if the determined level of dissolved oxygen is above a predetermined level. The compositions and methods can lower the amount of VFA present in the aqueous industrial system.

Activated ferrate solutions, methods of their preparation, and methods of disinfecting surfaces and oxidizing pollutants in water are provided.

Activated ferrate solutions, methods of their preparation, and methods of disinfecting surfaces and oxidizing pollutants in water are provided.

A waste treatment includes a package with compartments. A surfactant, an oxidizing agent, and, optionally, a liquid may be disposed within the compartments. The oxidizing agent is within a compartment that does not contain the surfactant or the liquid. A bursting force may unseal a sealed end of each compartment. The liquid flushes the surfactant and the oxidizing agent out of the package into a non-contact agitating toilet. A dual compartment package made with a fluidly disintegrable material may separate the surfactant from the oxidizing agent where the liquid may not be provided. The waste treatment may be mixed with a waste deposited within the non-contact agitating toilet. The package may disintegrate in the presence of the liquid to allow the reactive components to mix. A plurality of waste treatments may be connected. A perforated barrier may separate a first waste treatment from a second waste treatment.

An advanced hydrodynamic cavitation system includes a housing, a first stator with angled ridges, a second stator that is circular with angled ridges, a rotor having rotor blades housed within the second stator, and a driveshaft, and is configured to work with a motor, a pump, and oxidizing agents such as hydrogen peroxide or ozone to form free radicals. Hydrodynamic cavitation occurs (1) on the leading edge of the rotor blades; (2) in the constriction between the rotor blades, depending on the design; (3) in the gap between the first stator and the rotor blades; and (4) in the gap between the second stator and the rotor blades. The four cavitation regions may coalesce to become a steady-state supercavitation cloud that removes unwanted, toxic or contaminated organic and inorganic compounds, specifically with the ability to treat and decontaminate sludge, wastewater, ballast water, drinking water, harmful algal blooms, and biomedical waste.
