The present invention relates to the use of a colloidal precipitated calcium carbonate (cPCC) for adsorbing and/or reducing the amount of at least one organic material in an aqueous medium.

An anaerobic digestion system is provided that includes a blend tank operable to control and perform pre-treatment of feedstock. An anaerobic digester is operable to digest the feedstock provided from the blend tank in a totally enclosed oxygen-free environment within a specific temperature range. A bio-mass tank processes liquid digestate from the anaerobic digester. One or more baffles are positioned in the digester, with the one or more baffles providing for plug flow through at least a portion of the digester to create baffled zones that are at least partially operable independently of adjacent baffled zones. A bio-mass tank processes liquid digestate from the anaerobic digester. An energy source is coupled to the anaerobic digester.

Processes are provided which utilize fiber conduit reactors/contactors to effect extraction from a fluid stream, particularly a fermentation broth, a waste stream of a fermentation process, a fluid comprising a dye, or a fluid comprising a pharmaceutical compound. In particular, methods are provided which include introducing a first stream comprising an extractant and a second stream which is substantially immiscible with the first stream into a conduit reactor proximate a plurality of fibers. The streams are introduced into the conduit reactor such that they are in contact with each other and the extractant of the first stream interacts with the second stream to extract a fermentation product, a fermentation byproduct, a dye or a pharmaceutical compound from the second stream into the first stream. The method further includes receiving the first and second streams in collection vessel/s and withdrawing separately the first and second streams from collection vessel/s.

The present invention relates to the use of a colloidal precipitated calcium carbonate (cPCC) for adsorbing and/or reducing the amount of at least one organic material in an aqueous medium.

Utilizing mobile walls, a transportable (or stationary) low cost, low carbon footprint process and apparatus with a granular filter media dry cell (for filter or bed) for dewatering particulate solids from liquid. The mobile wall structures can be made of a rigid structure constructed of new or preferred salvaged materials, assembled, with watertight joints, used, disassembled and stored for redeployment. The walls are set in a keyway utilizing whatever soil composition is available. The walls can be used in the previous Deskins filters as old wall replacement or new wall construction. The invention utilizes a generator that is not dependent upon site or local electricity thus can be operated in any location. All parts can be engineered, fabricated according to the design of the Quick-Dry Filter Dewatering Mobile Process and Apparatus, packed in shipping containers and be readily available for any immediate need.

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.

A system may include a catch tray coupled with a flow distributor. A mesh screen and carriage may be positioned within the catch tray. A drive bar may be coupled with the carriage and a pitman arm. A gear box may be coupled with a motor and the pitman arm. A process may include distributing contaminated fluid onto the mesh screen. A screen plane of the mesh screen may be at a screen angle that is oblique relative to the direction of the force of gravity. The screen plane is defined by a top surface of the mesh screen. The process may include moving the carriage in a reciprocating linear motion by rotating the pitman arm, and spraying a liquid onto the mesh screen. Liquid may flow through the mesh screen forming clarified liquid, and contaminate may move along the top of the mesh screen to a contaminate outlet.

An anaerobic digestion system is provided that includes a blend tank operable to control and perform pre-treatment of feedstock. An anaerobic digester is operable to digest the feedstock provided from the blend tank in a totally enclosed oxygen-free environment within a specific temperature range. A bio-mass tank processes liquid digestate from the anaerobic digester. One or more baffles are positioned in the digester, with the one or more baffles providing for plug flow through at least a portion of the digester to create baffled zones that are at least partially operable independently of adjacent baffled zones. A bio-mass tank processes liquid digestate from the anaerobic digester. An energy source is coupled to the anaerobic digester.

A biofiltration system for filtering wastewater includes a tower containing a packed bed on which biofilm is able to form and an air inlet below the packed bed and an air outlet above the packed bed. A water feed above the packed bed disperses wastewater over the packed bed. The biofilm serves as a biological contact reactor removing organic and/or inorganic contaminants from the water. Following filtration of the water through the packed bed, filtered water and solid waste sloughed off from the packed bed collects in a sump below the packed bed. Water flows from a water outlet in the sump to a centrifugal separator that separates solid material from water drawn from the sump to expel a waste stream and a filtered water stream.

A method of recovering palatable potable storable water from a process for concentrating an extracted juice, the method including the steps of: providing the extracted juice; concentrating the extracted juice to form a concentrated juice stream and a concentrator waste stream, wherein the concentrator waste stream is not palatable, potable or storable; and purifying the concentrator waste stream to provide palatable potable storable water including the step of passing the concentrator waste stream through activated carbon.
