Chemically oxidizing a wide range of targeted contaminants in soils, sludges, groundwater, process water, and wastewater and assisting in the eventual (over time) biological attenuation of the contaminants utilizing persulfates activated by trivalent metals, such as ferric iron. The use of trivalent metal activated persulfate results in a chemical oxidation process that yields degradation compounds which facilitate further attenuation via biological processes.

The present disclosure relates to a biofilter for wastewater digestion, in which a high degree of contaminant removal is obtained with a single device. In order for these levels to be achieved, the following are essential: the shape of the biofilter, the supply/discharge ratio of the biofilter, the position and height of each of the components and, finally, the combination of two packed zones, namely: a random zone, and a zone arranged in the form of ringed or corrugated tube bundles.

A brine waste management method comprising the utilization of brine waste as a growth medium for cultures of genetically modified halophiles acting as bio-refineries creating chemicals of value. Brine waste enters the method (101) to undergo compositional analysis (102), Pretreatment (104), and Inoculation (106). The compositional analysis (102) and the selection (103) of the chemicals of value influences the selection (103) of the halophile species to undergo modification (105), as well as the pretreatment (104) needed to encourage growth-production (107). Growth-production (107) is monitored and assisted until the extraction (108) of the chemicals of value and additional post-extraction (109) handling of excess brine waste exiting the method.

A method for the treatment of organic waste, the method comprising alternating steps of anaerobic digestion and aerobic composting conducted in a single reactor vessel, wherein at or about the completion of the anaerobic digestion step at least a portion of any free draining fluid from the reactor vessel is directed for reuse in subsequent anaerobic digestion steps, and solids remaining in the reactor vessel from the anaerobic digestion step are subjected to a dewatering step from which a liquid is obtained that is ultimately also directed, at least in part, for reuse in subsequent anaerobic digestion steps. A method for the management of biology in a batch process, wherein the batch process is an anaerobic digestion process, is also described.

Methods for capture of biogas from a wastewater system are disclosed herein. The methods may include the step of collecting biogas within a collector chamber of a biogas collector formed at an elevated location in a wastewater system, the biogas being released from wastewater passing though the collector chamber. The methods may include the step of controlling the withdrawing of biogas from the collector chamber, and the step of capturing the biogas withdrawn from the collector chamber. The methods may include performing the step of collecting biogas within a collector chamber of a biogas collector by reducing a pressure within at least portions of the collector chamber. The methods may include the step of conveying biogas withdrawn from the collector chamber to a biogas disposer. Related apparatus for capture of biogas from a wastewater system are disclosed herein.
