A system for decomposing a waste material in an unlined landfill including a landfill site having at least one waste disposal zone for receiving the waste material. The system also includes a remediation system configured for extracting a mixture of leachate and groundwater from groundwater within or adjacent to the landfill site and feeding the mixture into the at least one waste disposal zone along with air and other nutrients to enhance a rate of decay of the waste material within the at least one waste disposal zone.

The present development is a method for producing a high concentration free amino acid soy hydrolysate composition and a method for using the resulting hydrolysate composition. The high concentration free amino acid soy hydrolysate is used to enhance the microbe population found in soil and wastewater. The enhanced microbe population can promote plant growth, particularly for use in brownfields and similar reclamation sites or on turf grasses, and can promote the digestion of sewage solids.

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.

The invention provides inoculants for the generation of a biologically active layer in a water treatment or purification device. In some embodiments, the invention provides inoculants for a biologically active zone in a wastewater treatment system or device, for example in municipal wastewater and sewage treatment. In other aspects, the invention provides inoculants for water purification, for example in municipal drinking water purification or in slow sand filtration. Inoculants of the invention increase the effectiveness of the above systems and devices in providing useable water.
