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.

Provided is a bead in which an adsorbent and an organic contaminant-degrading microorganism are supported, wherein an adsorbent for adsorbing organic contaminants is supported on the bead together with an organic contaminant-degrading microorganism for degrading the organic contaminants adsorbed to the adsorbent to allow for the adsorbent to remove organic contaminants in water and to allow for the organic contaminant-degrading microorganism to regenerate the adsorbent.

The present invention relates to methods and compositions for water treatment and environmental remediation using nanoparticle supported lipid bilayers (NP-SLBs). In one embodiment, the NP-SLBs are single or multilayer lipid bilayers of 1,2-dimyristoyl-sn-glycero-3-phosphocholine (DMPC) supported by silica.

A process and an associated facility for treating ammonium-containing wastewater are specified. Ammonium present in the wastewater is first oxidized to nitrite by use of aerobically oxidizing bacteria in an activation unit. Then ammonium and nitrite are reduced to elemental nitrogen anaerobically by use of ANAMMOX bacteria. Excess sludge arising in this operation is removed from the activation unit. ANAMMOX bacteria removed with the excess sludge are separated and returned to the activation unit. To facilitate the returning of the ANAMMOX bacteria, magnetic or magnetizable expanded glass particles are added, as colonization bodies for the ANAMMOX bacteria, to the wastewater in the activation unit. Expanded glass particles removed from the activation unit with the excess sludge are separated from the excess sludge magnetically and returned to the activation unit.

Provided is a bead in which an adsorbent and an organic contaminant-degrading microorganism are supported, wherein an adsorbent for adsorbing organic contaminants is supported on the bead together with an organic contaminant-degrading microorganism for degrading the organic contaminants adsorbed to the adsorbent to allow for the adsorbent to remove organic contaminants in water and to allow for the organic contaminant-degrading microorganism to regenerate the adsorbent.

Moving bed media serving as a growth surface for bacteria that remove soluble carbonaceous BOD, soluble inorganic ammonia nitrogen, phosphorous, nitrate nitrogen or nitrite nitrogen from wastewater are contained in a variable liquid depth, variable volume, hydraulic flow equalization basin. The equalization basin can be divided into different treatment sections by installing separator screens. Fat accumulation on the moving media, which could cause the media to float or in some other way cause the media to be ineffective, can be prevented by a fat, oil, and grease removal process in a dissolved air flotation cell upstream of the flow equalization basin containing the moving bed media. The moving bed media are retained in the basin by a suitable media screen as the liquid level and volume increases or decreases in the basin depending upon the effluent pumping rate vs. the influent flow rate.

A carbon-based aerogel doped or enriched with nitrogen and phosphorus is provided. Further, kits comprising the aerogel and oil-degrading bacteria are provided. Use of the kits for at least partially degrading a crude oil or a crude oil fraction is also provided.

The present disclosure belongs to the technical field of sewage treatment, and discloses a method and system for enhanced culture of aerobic granular sludge. The system includes a reaction tank, a water inlet and outlet unit, an aeration unit, and a sludge discharge unit. The water inlet and outlet unit includes a water inlet pump, a water inlet electric valve, a liquid flowmeter, a sewage uniform distribution treatment device, buffers, a water drainage pipe, and a water drainage electric valve. The aeration unit includes a blower, microporous aerators, and a gas flowmeter. The sludge discharge unit includes sludge discharge pumps, a sludge discharge pipe, a sludge discharge electric valve, and a sludge concentration meter. In the present disclosure, a multi-point uniform water distribution method is used. When the flow rate of influent water is adjusted, sewage slowly and uniformly flows through a sludge layer from the bottom of the system, so that the concentration of organic matter in raw water is prevented from being rapidly reduced by rapid single-point water intake, the utilization rate of the organic matter in the sewage is increased to the maximum extent, and the efficiency of the system is improved.

A method of preparing an amorphous iron sulfide carrier for removing nitrogen from water, which effectively removes nitrogen from wastewater containing nitrate nitrogen or nitrite nitrogen, includes the stabilizing step for an hydrogen sulfide saturated-iron hydroxide material by immersing the material in water for a certain period of time, a step (S10) of preparing iron hydroxide for hydrogen sulfide adsorption having pores and a surface capable of adsorbing hydrogen sulfide; a step (S20) of introducing hydrogen sulfide into the prepared iron hydroxide to reach the iron hydroxide and produce amorphous iron sulfide; and a step (S30) of stabilizing the amorphous iron sulfide produced by reacting with hydrogen sulfide, by immersing in water for one or more days.

The present disclosure provides an apparatus for absorption of contaminants. Further, the apparatus may include a substrate comprised of one or more of a biodegradable material and a non-biodegradable material. Further, the apparatus may include an absorbent medium incorporated with the substrate. Further, the apparatus may be configured to be disposed on a surface. Further, the absorbent medium includes a biochar. Further, the absorbent medium may be configured for absorbing one or more contaminants from one or more of the surface and an environment associated with the surface.
