Disinfection focuses on microbial inactivation to ensure water safety, while sanitization aims to control microbial levels and maintain hygienic conditions within the system.
Disinfection and sanitization are critical steps in water treatment and process liquid systems to control microorganisms, ensure product safety, and protect downstream processes. Unlike separation technologies that remove contaminants physically or chemically, disinfection focuses on microbial inactivation, preventing biological growth and cross-contamination throughout the system.
LPE provides appropriate disinfection and sanitization solutions by selecting suitable technologies and optimizing them for each specific system and application. These solutions are designed for a wide range of uses, including drinking and mineral water, pharmaceutical water, and ultrapure water systems that require hygienic design with very low or near-zero microbial levels.
LPE provides disinfection and sanitization systems and equipment, including:
Disinfection focuses on microbial inactivation to ensure water safety, while sanitization aims to control microbial levels and maintain hygienic conditions within the system. Disinfection is typically used to inactivate microorganisms in water before use, while sanitization is commonly applied to maintain hygienic conditions in pipelines, tanks, and distribution systems.
Many disinfectants are used either alone or in combination. Commercial formulations based on these chemicals are often considered unique products, designed to achieve specific disinfection performance under defined operating conditions.
Non-Chemical and Physical Disinfection Technologies
These technologies inactivate microorganisms through physical, thermal, or process-based mechanisms, minimizing or eliminating the need for conventional chemical disinfectants.
Sanitization is the process of reducing microbial contamination to acceptable and controlled levels within water systems and process equipment. Unlike disinfection, which focuses on immediate microbial inactivation, sanitization plays a critical role in long-term microbial control, system hygiene, and biofilm prevention—particularly in high-purity and pharmaceutical water systems
Uses elevated temperatures to inactivate microorganisms by protein denaturation, membrane damage, and nucleic acid degradation. Hot water sanitization is typically performed at ≥80 °C for a defined duration, while steam sanitization operates at higher temperatures with shorter exposure times. This method is chemical-free and leaves no residuals but requires systems designed to withstand high temperatures and thermal cycling
Utilizes oxidizing agents such as ozone, chlorine dioxide, peracetic acid, and hydrogen peroxide to disrupt microbial cell structures and metabolic processes. Chemical sanitization is highly effective against biofilms and spores but requires careful control of concentration, contact time, temperature, and pH, as well as compatibility with system materials and proper residual removal before returning the system to service
