The present disclosure describes a microorganism support structure, including a gas-permeable layer comprising two opposing surfaces; a microorganism adhesive coats at least one surface of the gas-permeable layer; and a microorganism disposed on the microorganism adhesive-coated surface of the layer. The microorganism adhesive enhances the adhesion of the microorganism on the layer compared to a gas-permeable layer that does not have the microorganism adhesive.

The present disclosure discloses a method for removing TBBPA in water, a microbial strain and a microbial agent, wherein the microbial strain is a domesticated Burkholderia cepacia strain, which is named Y17 with a conservation number GDMCC No. 62153. The microbial agent and the method for removing TBBPA in water with the microbial agent are that Y17 strains are colonized on the surface and pore channels of biochar, TBBPA in water is used as a carbon source, air and dissolved oxygen are used as oxygen sources, biochar provides the strains a growth microenvironment for degrading TBBPA in water, the strains are subjected to aerobic growth in water, and bio-enhanced degradation of TBBPA in water is performed by continuously degradation reaction. The removal method and the microbial strain as well as the microbial agent are high in degradation efficiency, environmental-friendly and low in cost, and can meet requirements on large-range promotion and application.

Conventional methods for treating fat, oil, grease (FOG) and other build-up in wastewater systems (including grease traps) of restaurants and the like typically rely on chemical-based detergents, which may be damaging both to the environment and to the wastewater system itself. While some bio-friendly alternatives are known, a common problem with all these agents is that they are “flushed through” the system rapidly, and thus are relatively ineffective and inefficient. In providing an onsite system and method comprising cultivating micro-organisms and then using a carrier to deliver them to an affected environment, the present invention provides a solution that is more efficient in requiring less “starter” ingredients as well as more effective in ensuring the cultivated micro-organisms are delivered to, maintain sustained contact with, and have adequate time to treat, the undesirable substance(s).

The present disclosure relates to the technical field of microbial electrochemical technology, in particular to a graphene-magnetite conductive skeleton electrode, a preparation method and application thereof, and a method for treating petrochemical wastewater. In the present disclosure, the surface roughness of the graphite rod electrode can be increased by the conductive skeleton modified on the surface of the graphite rod electrode, which is beneficial to the enrichment of microorganisms. The increase in the load of microorganisms will mean the amount of electroactive microorganisms will also increase, which will further improve the electron transfer ability, and because the material of the modified layer is a conductive material, it is also more conducive to the transfer of electrons; at the same time, the conductive skeleton modified on the surface of graphite rod electrode can also further enhance the transmission distance of electrons because of the skeleton constructed.

A composition for remediation of soil and groundwater containing halogenated compounds. The remediation composition includes an elemental iron-based composition, which may include activated carbon capable of absorbing the halogenated compounds with numerous pores impregnated with elemental iron. The remediation composition further includes a first bioremediation material including a blend of one-to-many organisms capable of degrading the halogenated compounds. The remediation composition includes an organic compound or polymeric substance and a second bioremediation material including a blend of one-to-many organisms capable of degrading the organic compound or polymeric substance over time (e.g., 20 to 365 or more days to provide a time release substrate-creating material or platform) into smaller molecules or compounds used by the organisms in the first bioremediation material while degrading the halogenated compounds. The organic compound may be a complex carbohydrate such as food grade starch, chitin, or other complex carbohydrate such as one with low water solubility.

The present invention relates to systems and methods for catalytic removal of per- and polyfluoroalkyl substances (PFAS) from water and wastewater. The system and methods utilize a catalyst film and a biofilm to synergystically remove PFAS from water. In some aspects, the catalyst film reduces and defluorinates PFAS into less fluorinated counterparts of PFAS, and the biofilm metabolizes the less fluroinated counterparts of PFAS into CO.sub.2 or shorter chain PFAS.

This invention relates to a composition comprising: (a) 10-20 wt % acidifying bacteria, (b) 30-40 wt % of an oxidising agent, (c) 5-15 wt % of an organic acid, and (d) 1-10 wt % of a chelating agent. The invention also relates to a method of removing uric acid from a waste pipe comprising the step of inserting the composition into the waste pipe.

A medium material for removing phenol contamination from groundwater, a method of producing the same, and use of the same id disclosed. In at least some embodiments, the medium material is a granular material which has an average particle diameter of 0.5-1.5 cm and is formed from a bacteria-entrapping solution, a manganese sand filter material, modified bentonite, and biochar at a mass ratio of 1:0.2-0.4:0.2-0.4:0.1-0.2 by a series of processes including strain culturing, catalysis, mixing, solidification, and the like. The medium material can remove phenol from groundwater, is a safe and environment-friendly material, has a long service life, and/or achieves waste treatment with waste.

The present invention relates to a bio electrochemical system for the treatment of organic liquid wastes. The bio electrochemical system comprises a container; at least one tube shaped separator vertically disposed such that it penetrates the container; at least one anode disposed in the external space of the tube shaped separator; at least one cathode disposed in the interior space of the tube shaped separator; and at least one partition plate horizontally disposed such that it forms multistage horizontal flow channels for organic liquid wastes in the container.

The present invention provides a biological microbial treating agent, for radioactive material removal, comprising at least one type of microorganism selected from Bacillus amyloliquefaciens KS-R01, Bacillus siamensis KS-R02, Bacillus velezensis KS-R03 and Bacillus tequilensis KS-R04.
