Abstract:
A method for manufacturing a creped fiber web is provided and includes providing a rotating cylindrical dryer surface, applying an ionene adhesive to the rotating cylindrical dryer surface to form an adhesive dryer surface, conveying a fiber web to the adhesive dryer surface, drying the fiber web on the adhesive dryer surface to form a dried fiber web, and creping the dried fiber web from the adhesive dryer surface. The ionene polymer can be a crosslinked polymer of an alkylamine, a haloepoxyalkane, and an amine that differs from the alkylamine, such as a terpolymer of dimethylamine, epichlorohydrin, and ethylenediamine. The ionene adhesive may further include monoammonium phosphate. The ionene polymer may be water-soluble and cationic.

Abstract:
Various embodiments of the present disclosure relate to proactive dosing optimization chemical feed units producing an output solution (such as an oxidizing biocide) therefrom. Online sensors (142) generate signals corresponding to directly measured variables for respective process components. Information is selectively retrieved from models relating combinations of input variables to respective industrial process states, wherein various current process states may be indirectly determined based on directly measured variables for respective system components. An output feedback signal is automatically generated corresponding to a detected intervention event based on the indirectly determined process state. A controller may receive the signal and implement, e.g., regulation of oxidizing biocide feed for optimization of end products and/or performance metrics.
Abstract:
Methods to improve water treatment for industrial uses are described. One method involves admixing source water, such as from a river or other flowing source or body of water, with a at least one water-soluble cationic polymer and at least one chloramine and a coagulant and/or flocculant to provide a treated water. The at least one water-soluble cationic polymer and at least one chloramine are present in an effective amount to improve water treatment efficiency, such as in allowing use of reduced amounts of coagulant and/or flocculant, and/or reduced suspended solids, turbidity, and/or color clarification.
