Innovative Solutions for Effective Foam Management
Uncontrolled foam in industrial processes across water, wastewater, and paper production can lead to production losses, quality deviations, and higher operating costs. Kurita’s advanced foam‑control technologies offer a reliable, sustainable, and automated way to eliminate foam‑related issues across industrial applications.
Kurita® FC – High Performance Foam Control Agents
Kurita® FC represents our diverse portfolio of silicone-based and silicone‑free defoamers engineered to deliver powerful foam control with a low COD contribution, a key advantage for environmentally conscious operations.
These defoamers are designed to meet modern regulatory and application demands:
- Compliant with BfR (Bundesinstitut für Risikobewertung) requirements
- Compliant with FDA standards for safety in specific industrial processes
- Suitable for both preventive and curative foam control applications
- Designed to fulfill performance needs in specialized applications across multiple industries
Operational Benefits of Kurita® FC
Kurita® FC defoamers provide robust performance in water, wastewater, and paper processing environments, supporting:
Quick foam knock down
Fast response to acute foaming events
Foam prevention
Stabilizes processes and reduces chemical consumption
De-aeration
Removes entrained air for improved product quality and smoother operation
While Kurita® FC delivers robust chemical foam suppression, Kuriauto Foam Control takes the next step, adding intelligent automation that adjusts foam control in real time for maximum efficiency.
Kuriauto Foam Control – Intelligent Automated Foam Management
Kuriauto Foam Control enables automated and precise foam regulation in any liquid media. It improves operational efficiency by activating antifoam dosing only when needed, helping avoid overdosing and unnecessary chemical use.
Key Features
- Reliable foam detection based on conductivity changes
- Automatic activation of alarms and/or defoamer dosing
- False-signal reduction thanks to smart probe design
- Easy installation with minimal maintenance beyond periodic cleaning
Kuriauto ensures consistent foam control, optimized chemical use, and greater process stability.

Expert Q&A
Foam formation causes problems in processes and wastewater treatment because it reduces effective reactor volume, disrupts mass and oxygen transfer, and interferes with solids separation and control systems.
Excessive foam can lead to biomass washout, loss of treatment efficiency, sensor malfunctions, and uncontrolled overflows, creating safety, hygiene, and environmental risks.
As a result, foam is not just a nuisance but a direct operational and process‑stability challenge.
Yes. Kurita provides specialized defoamers and wet‑end deaerators tailored to the requirements of papermaking, including products optimized for wet‑end control and size press applications. All paper industry defoamers comply with relevant regulatory standards such as FDA, BfR, RAL UZ, EU Ecolabel, and Nordic Swan.
Kurita offers a comprehensive defoamer portfolio, including both silicone‑based and silicone‑free solutions. The silicone‑free range covers oil‑based, polymer‑based, and surfactant‑based defoamers, as well as emulsion‑based deaerators. Depending on the application, Kurita provides defoamers for the process industry, indirect food contact, and the paper industry, along with specialized solutions for oil and gas, mining, and high‑temperature applications.
Kurita’s KuriAuto Foam Control automation technology enables reliable and sustainable foam control through automated defoamer dosing. A robust probe detects foam formation in real time and triggers dosing only when required. Its intelligent design minimizes false signals, ensuring stable operation while reducing chemical consumption. This approach improves process safety, lowers operating costs, and supports sustainable use of defoamers.
