Improved methods for anaerobic digestion of organic matter to produce biogas. Among the improvements given are including ferric iron in a hydrolysis reactor to increase the rate and efficiency of anaerobic hydrolysis to provide substrates for methanogenesis. A solids separation step is added after hydrolysis and before methanogenesis to improve the efficiency of the methanogenesis step. Other improvements involve using separate tanks for the hydrolysis and methanogenesis stages and using two (or more) methanogenesis tanks in sequence, and switching the order of the two (or more) methanogenesis tanks periodically.

Disclosed is a photobioreactor system that reduces pollutant gases, mainly ammonia and carbon dioxide, released in poultry houses with microalgae and reduces dust and particulate matter in the internal environment of the poultry house, and also creates a brighter and more spacious environment for animals in the internal environment, while creating an insulation effect on the exterior of the poultry house by integrating into the exterior wall.

A method and system for processing biomass. The method uses an apparatus with a housing, a rotor inside of the housing, and a plurality of protrusions extending from the rotor. The method includes placing the biomass in a fluid medium, inducing cavitation within the fluid to partially separate the biomass, sending the biomass and fluid into the housing, rotating the rotor to further separate the biomass, heating the biomass and fluid, and maintaining the acidity of the fluid and biomass at a pH of between approximately 2 to 6. The system includes apparatus each having a housing and a rotor within the housing. One apparatus has abutting, alternating height protrusions extending from the rotor. Another apparatus has grooves formed in the rotor and an end wall of the housing. Another apparatus has two rows of protrusions extending from the rotor that are spaced apart no less than approximately 6 millimeters.

The embodiments disclosed herein generally relate to systems, devices and methods for the fractionation, isolation, extraction and processing of the adipose supernatant layer of a bone marrow aspirate. In particular, the various embodiments relate to systems, devices, and methods of obtaining, utilizing, and processing the adipose supernatant layer of a bone marrow aspirate as a source of mesenchymal stem cells.

Methods and systems for using one or more stillage compositions generated at a bioprocessing facility for anaerobic digestion. Two or more anaerobic digestion digesters are configured with respect to each other based at least on the suspended solids content and soluble solids content of each process stream that is fed to each anaerobic digestion digester.

Improved processes and systems for recovering products from a corn fermentation mash. In some examples, a process recovers an oil product, a protein meal product, and a fiber product from a slurry. A process includes the following steps: introducing the slurry into a device with a flexible screen and mechanical agitation to produce a filtrate and a fibrous solid stream; and introducing the filtrate into a three-phase centrifuge to produce an oil stream, a high protein solids stream, and a water with solubles stream. The flexible screen includes a washing nozzle. The slurry is whole stillage from an ethanol process. The three-phase centrifuge is a three-phase decanter. The filtrate is heated before introducing into the three-phase centrifuge. The filtrate is optionally evaporated before introducing into the three-phase centrifuge.

An organic solid waste anaerobic digestion device based on uncoupling of hydraulic retention time (HRT) from sludge retention time (SRT) includes a self-sustaining air flotation screening tank. A sludge pipe of the self-sustaining air flotation screening tank is connected with a first separating mechanism. A bottom of the first separating mechanism is connected with a second separating mechanism, and two separating mechanisms are connected with a return pipe of the self-sustaining air flotation screening tank. Through the two separating mechanisms, the heavy inert materials at the bottom of the self-sustaining air flotation screening tank can be subjected to swirl separation, so that the liquid part, the solid part and the gas part can be completely separated, and then the useful active materials are conveyed to the reaction device.

The present invention relates to a processing method at acidic or neutral pH in a reactor (4) for processing lignocellulosic biomass (P), said process including a continuous cleaning phase of the reactor which comprises introducing a basic aqueous solution (EB) into said reactor containing the biomass being processed.
