Custom Formulated Microbiocides

Founded in 1983, Ques Industries, Inc. specializes in the production of EPA-registered microbiocides that help prevent the dangers and costly damage to water treatment systems. With our toll manufacturing capabilities, we can produce both standard and custom formulations using raw or semi-finished materials on behalf of our customers. Our microbiocides include Quaternary Ammonium compounds, Sodium Hypochlorite, Carbamates, Isothiazoline, Gluteraldehydes, DBNPA, BCDMH, Sodium Bromide, Bromine Chloride, Hydrogen Peroxide, and Sodium Chlorite. As a distributor and manufacturer for various microbiocides, we can also provide EPA sub-registrations under our customer’s label; acting as an agent of the registrant.

Each formulation begins using an extensive problem assessment and evaluation of our customer’s existing treatment system. We study their initial corrosion and biological developments, analyze energy and maintenance costs, production down time, compliance failures, and any related health issues associated with microscopic build up. Our microbiocides are used for FDA incidental contact applications, agricultural processing, public water systems, manufacturing, and water utility services. We can also design formulations for the specialized treatment needs of boilers, cooling towers, and humidifiers. With our water treatment maintenance services, we can assist with corrective and predictive maintenance as well as the prevention of emergencies or system down time. Our programs can support our customers with reverse engineering solutions, water analysis, in-house product testing, and custom GHS compliant SDS/label generation.

Our chemists field over 60 years of combined experience in the treatment of microbiocides for a variety of industries including commercial, public water utility, manufacturing, metallurgy, food & beverage, and property management. We’re an ISO 9001:2015 certified facility that takes pride in our work, conducting extensive quality control procedures while continuously updating our technology and processes. We closely follow the latest industry standards from AWT, FDA, and the EPA. To learn more about our services, please contact us directly or refer to the table below.
