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, a system and an apparatus for wastewater treatment using a combination of separation of fat, oil and grease (FOG) and biological treatment for reducing the amount of fat, oil and grease (FOG) in wastewater with the aid of a liquid culture of microorganisms is provided. In particular, the technology disclosed relates to a method and process for the separation and treatment of FOG, as well as a container tank and an outlet pipe construction adapted for improving the gravimetric FOG separation process and the breaking down of FOG using microorganisms.

The microorganism preparation feeding method of the invention employs an automatic microorganism preparation feeding apparatus which includes a cold storage apparatus for refrigeration-storing a seed microorganism belonging to the aerobic microorganism group including at least one species of aerobic microorganisms capable of decomposing oil and fat contained in oil/fat-including wastewater and a growth tank for growing the seed microorganism so as to produce the microorganism preparation, wherein the seed microorganism belonging to the aerobic microorganism group is maintained in a live state by means of the cold storage apparatus, the seed microorganism is periodically grown by means of the growth tank so as to produce a predetermined microorganism preparation, and the produced predetermined microorganism preparation is fed to the oil/fat-including wastewater. The method includes refrigeration-storing, as the seed microorganism, a microorganism whose population density is 1×10.sup.7 CFU/mL to 5×10.sup.9 CFU/mL in the cold storage apparatus; growing, as a source material, the seed microorganism of a predetermined volume by means of the growth tank so as to produce the predetermined microorganism preparation whose volume is 50 to 500 times the predetermined volume of the seed microorganism and whose population density is 1×10.sup.7 CFU/mL to 2×10.sup.10 CFU/mL; and feeding the produced microorganism preparation to the oil/fat-including wastewater.

The technology relates to an apparatus, methods and applications to grow microorganisms on-site to treat contaminated environments. The apparatus is designed to function under a wide range of environmental conditions including extreme cold, extreme heat and direct exposure to sunlight. Such environments normally reduce the shelf-life of the organisms in the storage chamber that feeds the fermenter where they are being grown. These environments can also lower the growth rate of the organisms in the fermenter causing diminished cell output. Quite often the optimum point of application for the organisms is outdoor and too far from structures with appropriate protection from ultraviolet radiation from the sun or from excessive cold or hot weather. The technology in the application addresses these issues.

A method of treating cooling circuit water of industrial plants (2) contaminated with organic substances and inorganic particles, comprises the following steps: a) separating the organic substances and inorganic particles from the cooling circuit water to obtain precleaned cooling circuit water; b) cooling the precleaned cooling circuit water by an open cooling tower (11) to obtain cooled precleaned cooling circuit water; c) desalinating at least a partial volume flow of the cooled precleaned cooling circuit water by an desalination plant (14) to obtain cleaned cooling circuit water; and d) adding bacteria capable of degrading organic substances present in the cooling circuit water. The bacteria are added to the cooling circuit water before the separation in accordance with step a), before the cooling in accordance with step b) and/or before the desalination in accordance with step c), to form a biological cleaning stage.
