Legionella Control

What is Legionella?

Incidents of human illness and fatality due to pathogens in industrial, commercial and institutional, and municipal water systems continues to be increasingly prevalent in the news.

Industrial water systems often represent an ideal place for the growth and multiplication of microorganisms, causing a decrease in system performance but also can cause severe sanitary problems in water systems, such as Legionellosis.

At Kurita, we offer an integrated approach that combines chemistry, equipment, engineering, and service to tackle the challenge of Legionella in water systems. Our comprehensive treatment solutions are designed to protect our customers’ systems against this harmful pathogen.

Risk assessments

To determine the presence of Legionella and recognize potential hazardous areas and situations where its proliferation may occur. This process involves identifying, evaluating, and estimating the levels of risk associated with a given situation, comparing them with industry standards, and establishing an acceptable level of risk.

Action Plan

After an Audit we create a personalised and self-management plan tailored to your specific needs. This plan outlines the necessary steps and strategies to address and mitigate the identified risks effectively.
