Described herein are fouling control compositions including cationic alkyl polyglycosides to reduce microbial and/biofilm growth in a water system. The described compositions and methods of using the same are found to be more effective than those methods or compositions including commonly used single quaternary compounds for reducing microbial or biofilm growth in water systems.

Use of cationic sugar-based compounds for microbial fouling control in a water system

Disclosed herein are antifouling compositions and uses of antifouling compositions for controlling microbial fouling in a system in contact with an aqueous medium. The antifouling compositions comprising an antifouling compound of Formula 1

Antifouling compounds used for microbial fouling control

A method of producing chlorine dioxide is disclosed. The method may include feeding a reaction mixture into a separator. The reaction mixture may follow a helical path through the separator and produce gaseous chlorine dioxide within the separator. Gaseous chlorine dioxide may be withdrawn from the separator and used to disinfect process water.

Pure chlorine dioxide generation system with reduced acid usage

Disclosed herein are the methods of using specific di-cationic or multiple charged cationic compounds, which are derived from primary amine or polyamines through an aza-Michael addition with an α, β-unsaturated carbonyl compound or from polyamines through both an aza-Michael addition with an α, β-unsaturated carbonyl compound and a ring-opening reaction with an epoxide, in a fouling control composition to reduce microbial and/biofilm growth in a water system. The disclosed methods or compositions are found to be more effective than those methods or compositions including commonly used single quaternary compounds for reducing microbial or biofilm growth in water systems.

Use of multiple charged cationic compounds derived from primary amines or polyamines for microbial fouling control in a water system

A method of controlling a chemical reaction is disclosed. The method may include feeding a solution at a first flow rate into a reactor and detecting a sound in the reactor using a sound sensor that is adjacent to the reactor. The sound sensor may convert the sound into a sound signal. After the sound signal is acquired, it is compared to a stored sound signal or a stored sound threshold to detect a reaction event. The method may include adjusting the flow rate of solutions into the reactor in response to the reaction event.

Decomposition mediation in chlorine dioxide generation systems through sound detection and control

The disclosed systems and method utilize the autofluorescence, optic imaging, and heat transfer resistance technologies to monitor the same simulated surface area for deposits. The systems and methods may provide continuous monitoring, detection, characterization and quantification of deposits. Utilizing this information, an associated control system may initiate alarms, initiate a chemical treatment operation, and adjust corresponding chemical treatment and preventive protocols to minimize and/or eradicate the issue.

System and method of inline deposit detection in process fluid

A cationic polymer salt composition is provided that includes a reaction product derived from reaction of a polyamine or a polyalkyleneimine and a substituted alkyl trialkyl quaternary ammonium salt. Also provided are surfactant compositions. The compositions may also include carriers, such as water, methanol, ethanol, propanol, isopropanol, butanol, isobutanol, monoethyleneglycol, an ethyleneglycol monobutyl ether, and hexylene glycol.

Quaternary cationic polymers

The present disclosure generally relates to methods of treating process water using a reactor for generating chlorine dioxide onsite. The onsite generation system may include double ensured precursor feeding, effective reactor, automated control/alarm, and effective product delivery. The reactor may include a mixing device, a first feed line connected to the mixing device, and a second feed line connected to the mixing device. The reactor may include a proximal portion in fluid communication with the mixing device and a distal portion in fluid communication with a motive water line. The mixing device, the reactor, a portion of the first feed line, and a portion of the second feed line may be positioned within the motive water line.

Low risk chlorine dioxide onsite generation system

Described herein are the methods of using a cationic alkyl polyglycoside in a fouling control composition to reduce microbial and/biofilm growth in a water system. The described methods or compositions are found to be effective than those methods or compositions including commonly used single quaternary compounds for reducing microbial or biofilm growth in water systems.
