A method for preparing a stable concentrated formaldehyde blend, the method providing a formaldehyde solution and a crude glycerol compound; and blending the formaldehyde solution and the crude glycerol compound to obtain a stable concentrated formaldehyde blend.

Methods and systems of controlling odor in. water by adding a humic composition to the water. The humic composition cm adsorb or otherwise neutralize malodorous compounds such as hydrogen sulfide, ammonia, and mercaptans. The methods are useful in food and. agricultural industries where the water may come in contact with food items.

In an embodiment a method for treatment wastewater includes exposing the wastewater to an alternating electromagnetic field in order to remove a content substance from the wastewater and selecting a resonance frequency or a frequency in proximity to the resonance frequency for splitting up and for flocculating the content substance or pails of the content substance.

A system and method for processing sewage sludge using pyrolysis to eliminate and/or significantly reduce organic chemical compounds, including plastics, and to produce a biochar product that is safe for beneficial uses is provided. The system and method can utilize pyrolysis to treat sewage sludge which dramatically reduces or eliminates regulated and unregulated synthetic organic chemical compounds in the resultant biochar.

The present disclosure relates to a process for treating and regenerating a spent caustic solution at ambient temperatures and pressure which includes oxidizing spent caustic wastewater with a brine solution and ozone mixture, supported by irradiation of the spent caustic wastewater by ultrasound. A range of wastewater treatment techniques may also be included to reach a desired effluent quality level.

A thermal management system includes a space structure, a feed water container, a water feed line, a pump, and a filter device. The space structure includes a heat source connected with a fluid loop for conveying a working fluid through the heat source to regulate temperature and a sublimator connected with the fluid loop to receive the working fluid. The sublimator has a porous surface. The water feed line is connected with the container and the sublimator. The pump is located in the feed water line and is operable to move the feed water from the container to the sublimator. The sublimator is operable to cool the working fluid using the porous surface. The filter device is located in the water feed line between the pump and the feed water container. The filter device includes an adsorbent bed to remove organic compounds.

Disclosed are compositions for degrading organic compounds, the composition comprising a support comprising one or more of a polyolefin and a compound comprising silicon and an acid anhydride of the structure:

##STR00001##

grafted to the polyolefin and/or the compound comprising silicon; and one or more metal oxides bound with the acid anhydride; wherein A is a cycloalkyl, heterocycloalkyl, or fused ring system comprising at least one unconjugated -ene group. Also disclosed are processes for making the composition, and methods for degrading organic compounds in a fluid.

Articles can be provided with odor resistance by applying a dispersion of a halogenated heterocyclic N-halamine in an inert liquid carrier onto the surface of the article and allowing the inert liquid carrier to penetrate into it. The N-halamine accordingly becomes deposited on the surface of the article after the inert liquid carrier penetrates into the article. This method can be used to provide odor resistance to a variety of substrates, including garbage bags. It can also be used to deposit other functional particulates onto the surface of substrates having sufficient porosity to take up the vehicle. For instance, such functional particles can be oxidants that display antimicrobial and/or enzyme inhibitory efficacy or particles having toxin interaction potentials through oxidative degradation or adsorption of toxic substances in air and/or water, such as fluoride uptake by metal oxide microparticles.

A bacterium that degrades LAS and/or removes N is provided. The bacterium is taxonomically classified as Pseudomonas sp., and was deposited in China General Microbiological Culture Collection Center on Sep. 18, 2018, with the accession number of CGMCC 16502. The bacterium can be applied in the rural domestic sewage treatment, and has the effect of removing LAS and/or N pollution.

An alkaline aqueous ferric iron salt solution is disclosed. Generally, the alkaline aqueous ferric iron salt solution comprises ferric ions (Fe.sup.3+), potassium ions (K.sup.+), carbonate ions (CO.sub.3.sup.2−), bicarbonate ions (HCO.sub.3.sup.−), hydroxide ions (OH.sup.−), optionally nitrate ions (NO.sub.3.sup.−). Further, a molar ratio of the potassium ions to the ferric ions is generally at least 5.0. The ferric iron is complexed with carbonate, bicarbonate or both to form a water-soluble complex that is anionic in nature and highly soluble in the alkaline aqueous ferric iron salt solution at pH above 8.5, and a pH of the alkaline aqueous ferric iron salt solution is at least 8.5.
