Abstract: Disclosed are compositions and methods useful in applications relating to papermaking. The compositions and methods of the present invention comprise aldehyde-functionalized polymers designed to impart high paper strength and enhance water removal during the papermaking process. The aldehyde-functionalized polymers are of relatively low molecular weight, and comprise amino and/or amide groups mono-reacted and di-reacted at a ratio of at least about 1.5 to 1. The low molecular weight polymers of the present invention have the same strength and dewatering performance as corresponding high molecular weight polymers.

Abstract: A method of controlling a volatile fatty acid in an aqueous industrial system is provided in the present disclosure. The method includes determining a level of dissolved oxygen in process water in the aqueous industrial system and adding an effective amount of a control agent to the process water if the determined level of dissolved oxygen is above a predetermined level. The compositions and methods can lower the amount of VFA present in the aqueous industrial system.

Abstract: The present disclosure provides compositions and methods for treating volatile fatty acids and bacteria capable of producing volatile fatty acids. The compositions can convert acid-producing bacteria environments to nitrate-reducing bacteria environments. The compositions and methods can lower the amount of acid-producing bacteria present in the environment and thereby reduce the amount of volatile fatty acids present in the environment. The control agent may also inhibit the growth of acid-producing bacteria and volatile fatty acid concentrations. The compositions and methods can be used with any aqueous industrial system.
