The invention relates to cold temperature-resistant microbials for use in waste water treatment. More particularly, the invention relates to isolated Bacillus strains ALG and DRT, and strains having all of the identifying characteristics of these strains, and combinations thereof, for a use comprising the above-mentioned use.

A system for treating wastewater, such as laundry water or car wash water, using a combination of microfiltration and/or ultrafiltration membranes and reverse osmosis. The system can use these elements to pretreat water that is then filtered by a media filter to reduce turbidity.

Electrochemical devices capable of converting acidic aqueous byproducts of strained yogurt production into value-added materials, as well as methods of making and using these devices, are described herein. Assembly of an electrolytic cell or series of cells that contain an anode that oxidizes organic substances in the aqueous byproduct stream and a cathode that either reduces organic species or water is described. Electrolysis serves to break down the organic matter present in the liquid, such as lactic acid and lactose, as well as aid in the separation of whey protein matter. Gaseous products of this electrolysis process can be either sold or used in waste-to-energy schemes, thereby introducing an environmentally-friendly method for the electrolytic treatment of acid whey.

A multi-stage sweeping gas membrane distillation (MS-SGMD) system and a method of use are provided. The MS-SGMD includes a plurality of modules, wherein each module includes a feed chamber fluidically coupled to a feed line and a carrier gas line, wherein the feed line introduces a liquid feed into the feed chamber from a liquid feed tank, and wherein the carrier gas line introduces a carrier gas into the feed chamber. Each module includes a sweeping gas chamber fluidically coupled to a sweeping gas line and a sweeping gas return line, wherein a sweeping gas is passed through the sweeping gas chamber. Each module further includes a membrane separating the feed chamber from the sweeping gas chamber, wherein the membrane allows transportation of vapor from the feed chamber to the sweeping gas chamber while blocking liquid from moving from the feed chamber to the sweeping gas chamber.

A method of treating dairy wastewater includes receiving a dairy wastewater stream at a first pH from a dairy processing facility at an equalization tank, receiving the dairy wastewater stream from the equalization tank at a pump, and, based on at least one of the first pH or a second pH of the dairy wastewater stream upon exiting the equalization tank, receiving an acid to the dairy wastewater stream prior to the pump. A pump outlet stream includes a mixture of the dairy wastewater stream and the acid at a third pH that is lower than the first pH. The method also includes receiving the pump outlet stream at a pipe reactor in fluidic communication with the pump, then receiving the pipe reactor outlet stream at a dissolved air flotation (DAF) unit, and then outputting a liquid stream at a final pH from the DAF unit.

Embodiments described herein are directed to methods and systems for treating wastewater or storm water using vermifiltration. The wastewater can come from various sources, such as agricultural sources, municipal and industrial sources, wineries, the dairy industry, and many others. The systems can include vermicomposting beds that are capable of removing high amounts of contaminants, pollutants, and/or toxic substances from wastewater. The wastewater may be applied to vermicomposting beds, for example, by an irrigation system. The irrigation system may provide, for example, improved bed coverage and more even saturation. The vermicomposting beds can remove various harmful substances from the wastewater, such as petroleum products; industrial chemicals; heavy metals (e.g., lead, mercury, cadmium, arsenic); pesticides (e.g., atrazine, chlorpyrifos); and organic compounds (e.g., phenols, polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs)).

Airtight storage tank for the storage of manure (36) and/or whey, and an improved process for anaerobic treatment of manure (36) and whey using the same, with a transport phase (1) including a preliminary phase (2) of collection, transfer, control, treatment, and storage of manure (36) that includes waste transport, registration, and discharge into a storage tank (33), and a transport phase (1) under controlled anaerobic conditions following the preliminary phase (2), which involves discharging the contents of the storage tank (33) under anaerobic conditions into a tanker vehicle (14) and transferring (15) the volume of manure (36) removed with the tanker vehicle (14) to a predetermined location.

A method for treating an aqueous fluid comprising a biodegradable organic substance in an installation comprising an upflow bioreactor containing a sludge bed, said sludge bed comprising biomass, an external separator, and a conditioning tank, the method comprising: treating the fluid in the conditioning tank; feeding the treated fluid into a lower part of the bioreactor and forming biogas; withdrawing the fluid from an upper part of the bioreactor, which withdrawn fluid comprises biomass; feeding the aqueous fluid withdrawn from the upper part of the bioreactor into the external separator wherein the aqueous fluid comprising the biomass is separated into a liquid phase, and a fluid phase enriched in biomass; returning said fluid phase enriched in biomass from the external separator to the bioreactor; and returning a part of said liquid phase to the conditioning tank.

A method of preparing at least once cell suspension product for treating wastewater, comprising germinating seeds from one or more plants selected from the group consisting of M. peregrine, S. Potatorum, O. ficus-indica, O. basilicum, and H. tuberculatum to provide plant sprouts; cutting the sprouts to provide plant parts; adding the plant parts to a culture medium; adding a basal medium to the culture medium to initiate development of the cell suspension; maintaining the cell suspension for a period of time to harvest callus in the cell suspension; and isolating at least one cell suspension product from the cell suspension.
