“In wine there is wisdom, in beer there is freedom, in water there is bacteria.” – Benjamin Franklin
Overview
Microorganisms, including bacteria, viruses, and protozoa are commonly present in surface water, groundwater influenced by surface conditions, and reclaimed water supplies. If left untreated, these contaminants pose serious public health risks and can compromise regulatory compliance, operational reliability, and public confidence in the water supply.
Pureflow Treatment Technologies
Ultrafiltration (UF)
Ultrafiltration provides a reliable physical barrier for microorganism removal, including bacteria and protozoa, as well as suspended solids . UF systems are applied where consistent pathogen removal and low‑turbidity effluent are required, independent of upstream water quality variability. Pureflow UF systems captures particulates greater than 0.01-0.1 µ / 30 mn.
Ozone Disinfection
Ozone is a rapid, high-strength disinfectant; reacting up to 3,000 times faster than chlorine and is highly effective against bacteria, viruses, and chlorine‑resistant protozoa. Pureflow ozone systems are applied where high‑efficiency disinfection is required, while minimizing disinfection by‑product formation associated with conventional chemical disinfectants.
Advanced Oxidation (AOP)
In applications involving difficult‑to‑inactivate microorganisms or coincident organic contaminants, advanced oxidation processes are applied to enhance oxidation strength through hydroxyl radical formation. AOP systems are typically selected for reuse applications or complex source waters. Pureflow offers UV/H₂O₂, Ozone/UV, Ozone/H₂O₂ AOP processes.
Chemical Metering Systems
Chemical disinfectants, including liquid chlorine‑based systems, are applied where residual protection in the distribution system is required. These systems provide a proven and cost‑effective method for maintaining microbial control beyond primary treatment, ensuring disinfectant residual is sustained throughout storage and delivery to preserve water quality at the point of use.
