Installation and method for processing wastewater, comprising: a) providing wastewater for processing; b) reducing O2 content of said wastewater by unactivated aerobic digestion; c) subsequently to ‘b’, eliminating substantially all O2 from said wastewater by anaerobic digestion; d) subsequently to ‘c’, transferring said wastewater to a closed photobioreactor; and e) subsequently to ‘d’, maintaining said wastewater in said photobioreactor in conditions favorable for algal photosynthesis, thereby allowing algae to grow in said photobioreactor. A method for growing algae is also disclosed whereby time, density and flow speed are controlled. The photobioreactor may have a conduit with two proportions of different cross sections.

The invention relates to a continuous process for treating organic waste taking place in a plant, said process for treating organic waste comprising a process of anaerobic digestion of a first part of said waste, which takes place in at least one digestion chamber, and a process of aerobic composting of a second part of said waste, which takes place in at least one composting chamber, the process for treating organic waste comprising the steps of:—collecting digestate and biogas at the end of said anaerobic digestion process,—collecting compost and humic percolate at the end of said aerobic composting process,—feeding at least part of said digestate

The subject invention provides methods for improving the treatment of effluents and waste matter produced during food processing and production. In particular, the subject invention provides methods for remediating fats, oils and greases (FOG), suspended solids, proteins, and other organic matter that are discharged from plants that process, for example, meats, poultry, seafood, dairy and plant-based oils. The methods of the subject invention utilize a customized microbial cocktail comprising facultative anaerobes, in combination with one or more microbial growth by-products, e.g., enzymes and/or biosurfactants, to digest and/or liquefy food processing waste matter.

A system for treating organic feedstock, particularly livestock or poultry wastewater. The system employs combined anaerobic and aerobic digestion for converting the wastewater into safe water, fertilizer, and energy, wherein sequencing batch reactors (i.e. ASBR and SBR) are used for the digestion process.

A method of producing a final product from a wastewater dissolved air flotation (DAF) sludge which includes the following dewatering step: 5—dewatering of the sludge, an aged sludge or a pre-processed sludge to produce a sludge filter cake and a filtrate; such that the pre-processed is sludge, or aged sludge, that has undergone additional processing steps prior to dewatering and aged sludge is sludge that has been stored for a period of time, wherein the dewatering step is a mechanical dewatering step 10 carried out at a maximum of 30° C. which results in a sludge filter cake that does not flow under its own mass.

A method for differentially lysing a liquid sample or target material using an augmented oxidizing agent (AOA), which includes a quantity of electronically modified oxygen derivatives (EMODs). The method reduces or eliminates total dissolved solids (TDS), total suspended solids (TSS), Biologic Oxygen Demand (BOD), microbial concentration, biofilms and other content in the liquid target material known or suspected to contain animal fluids, blood and blood cells and suspected or known to contain eukaryotic cells, microbial cells, bacteria, viruses, spores, fungi, prions, organic matter, minerals, proteins or associated structures. The BOD, TDS and TSS can be lowered or eliminated as desired. This action is directly proportional to the quantity of EMODs in the AOS applied to the liquid target material.

A method for treating wastewater or sludge includes treating a sludge having a first viscosity of from about 3,000 cP to about 15,000 cP by shearing the sludge to obtain a treated sludge having a second viscosity of less than 3,000 cP, where the second viscosity persists for a period of time. The sludge may be thickened by dewatering. A chemical agent may be added to the thickened sludge during, before, or after shearing. The treated sludge may further be pumped, transported, or otherwise handled.

A treatment of demineralization effluents, particularly recycling effluents, a method for demineralizing whey and treating the effluents, and a facility for implementation thereof. The treatment of whey demineralization effluents includes: i) supplying a whey demineralization effluent, ii) treating by reverse osmosis effluent recovered in i) to obtain a reverse osmosis permeate and retentate, iii) neutralizing the retentate pH, iv) treating the neutralized retentate by nanofiltration to obtain a permeate including monovalent ions and a retentate including divalent ions and residual organic materials, v) treating the permeate in iv) by electrodialysis with bipolar membrane to obtain acidic solution(s) and basic solution(s). Thus, it is possible to treat effluents, limit their environmental impact, generate solutions for the whey demineralization process, reduce the cost of whey demineralization because some process water from electrodialysis comes from treatment of the generated effluents, and reduce the total amount of effluent sent to the wastewater treatment plant.

Process for treating an aqueous fluid whereby a biogas is produced in an installation comprising a bioreactor and a separate container, the process comprising (i) a bioreactor feeding stage; (ii) a batch reaction stage, wherein biogas is formed and formed biogas is temporarily stored in the separate container, and at least one further stage (iii) comprising a settling stage and/or an aqueous fluid effluent discharge stage, wherein the biogas stored in the separate container is used to reduce fluctuations in a biogas exit flow from the installation. An installation for carrying out the process and the use thereof.

The present invention relates to a process for the separation of biomass in the anaerobic purification of wastewater and to a system for the separation of biomass in the anaerobic purification of wastewater.
