Abstract: Various implementations include a system and methods for capture and transfer of a liquid sample from a process to a sample analysis device. In particular, a sample of fluid can be contained in a non-pressurized line and first and second air-operated valves may prevent the fluid from flowing through the line. A third air-operated valve may be positioned on a stub-out of the non-pressurized line between the first and second air-operated valves. A sample line, also configured to contain a sample of the fluid, can extend between the third air-operated valve and a sample analysis device to transfer the sample of fluid to the sample analysis device. A first pneumatic valve can control air flow to the first and second air-operated valves; a second pneumatic valve can control air flow to the third air-operated valve; and a third pneumatic valve can control low-pressure air injected into the sample line.

Abstract: An immersed membrane cassette has a high tank intensity achieved by one or more of: reduced module to module gap; using structural hollow tubing in at least parts of a frame in place of separate permeate and/or air pipes; and, using vertical permeate port connections. The cassette has a tank intensity over 650 m2/m2. The cassette may be combined with a fine screen. This specification also describes an immersed membrane module having a permeate port and/or connector on the top of a header. The permeate connection between the module and a permeate collection tube may be vertical, i.e. perpendicular to the length of the header. A piston seal may be used between the permeate port of the header and the permeate collection tube. The permeate collection tube may be a horizontal structural member on the periphery of a frame that holds the module.

Abstract: A by-pass control sleeve has circumferential protrusions along its outer surface. The protrusions of the by-pass control sleeve may be distributed along the length of the sleeve with constant diameter sections of the sleeve therebetween. The protrusions may be asymmetrical and/or may have a steep and/or concave curved forward face. A method of making a by-pass control sleeve comprises molding the protrusions on an outer surface of the sleeve. A method of installing the by-pass control sleeve comprises sliding the sleeve onto an end of a spiral wound membrane element. A combination of the by-pass control sleeve fixed to the spiral wound membrane element may be installed in a pressure housing.

Abstract: A cord for supporting a biofilm has a plurality of yarns. At least one of the yarns comprises a plurality of hollow fiber gas transfer membranes. At least one of the yarns extends along the length of the cord generally in the shape of a spiral. Optionally, one or more of the yarns may comprise one or more reinforcing filaments. In some examples, a reinforcing yarn is wrapped around a core. A module may be made by potting a plurality of the cords in at least one header. A reactor may be made and operated by placing the module in a tank fed with water to be treated and supplying a gas to the module. In use, a biofilm covers the cords to form a membrane biofilm assembly.

Abstract: Stillage solids concentration methods are disclosed wherein a solids concentration aid is added to a process stream mixture in a corn to ethanol process. The solids concentration aid may comprise a cationic polymer coagulant or flocculant or both, a starch based coagulant or flocculant or a biologically derived (i.e., plant or animal origin) coagulant or flocculant. Acrylamide/quaternary ammonium copolymers and homopolymeric polydiallyldimethyl ammonium chloride polymers are noteworthy examples of suitable solids concentration aids.

Abstract: This specification describes membrane based filtration and softening systems and methods. A system has a microfiltration or ultrafiltration (MF/UF) membrane unit upstream of a nanofiltration or reverse osmosis (NF/RO) membrane unit, optionally with no intermediate tank. In some cases, the system and method may be used with feed water provided at municipal line pressure to the membranes. NF/RO permeate is collected in a tank and then pumped to a header. Treated water may be drawn from the header for use or recycled to the system, for example to backwash or flush one or both of the membrane units. In a combined process, NF/RO permeate flushes the feed side of the NF/RO unit and then backwashes the MF/UF unit. In another process, the MF/UF unit and NF/RO unit are filled with NF/RO permeate before being placed in a standby mode.

Abstract: Water containing selenium, for example flue gas desulfurization (FGD) blowdown water is treated with a combination of biological and chemical treatment and membrane filtration. The biologically treated water is dosed with a dithiocarbamate compound and flocculated prior to membrane filtration. Optionally, the treatment may be enhanced with one or more adsorptive agents prior to, or in conjunction with, membrane filtration. Membrane concentrate may be re-circulated to one or more biological treatment zones. The biological treatment may be by way of suspended growth, fixed growth on a moving bed, or both. One or more biological treatment zones may be controlled considering their oxygen reduction potential (ORP). Optionally, the biological treatment includes an aerobic zone following one or more anoxic or anaerobic zones. The non-aerobic zones remove selenium and optionally nitrogen and sulfur. The aerobic zone removes carbon, which may include carbon added as a nutrient in a non-aerobic zone.

Abstract: Methods are provided to inhibit corrosion in low hardness water systems. The corrosion inhibiting treatment comprises: calcium salts of low molecular weight polymer polycarboxylic acids. These calcium salts may be added preformed to the water system in need of treatment or formed in-situ in the system. This method of corrosion inhibition is not a source of addition phosphorous or heavy metal to the treated system.

Abstract: Verification plates for a bacterial endotoxin reader are provided, namely a temperature verification plate (TVP) and optical verification plate (OVP). The TVP has a body configured to be placed on a spindle of said reader and rotated by said spindle. The body has a temperature verification circuit with a temperature sensor and a temperature indicator. The temperature sensor is configured to measure a temperature of the body rotated by the spindle of the reader. The temperature indicator optically represents a value of the temperature measured by the temperature sensor. The temperature indicator is readable by an optical bench of the reader. The OVP has a body with a plurality of apertures located along a periphery that line up with an optical bench of the reader. Light produced by a light source of the reader can pass through the aperture and an intensity measured by a photodetector of the reader.
