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: The present disclosure provides an ion-exchange membrane that includes a supporting substrate impregnated with an ion-exchange material. The supporting substrate includes an imprinted non-woven layer, and the imprinting includes a plurality of deformations at a surface density of at least 16 per cm2. The supporting substrate may lack a reinforcing layer. In some examples, the supporting substrate may include only a single layer of the imprinted non-woven fabric.

Abstract: In a system and process described herein, wastewater such as pulp mill wastewater is treated with a membrane bioreactor (MBR) or another biological process coupled with tertiary filtration. An intermediate filtrate such as permeate from the membrane bioreactor is then treated with a tight ultrafiltration membrane optionally having a molecular weight cut-off of 500-4,500 Da on polyethylene glycol. Optionally, concentrate from the ultrafiltration membrane is sent to a black liquor evaporator of the pulp mill.

Abstract: Antifoulant compositions and methods are used for inhibiting fouling on structural parts of a system exposed to a fluid hydrocarbon or petrochemical stream. Polyamine antifoulants are added to such systems. The polyamine antifoulants may be conjointly used with dispersants and/or fatty acids. The fatty acids have been found to reduce thermal degradation of the polyamine antifoulants.
