Why using a certified chlorine dosing pump is important ?
IIn order to make the water drinkable, the Dosatron ACS or NSF certified metering pumps, installed in line with the water pipe, inject a dose of chlorine (NaClo, CaClo) which allows the destruction of organic matter such as viruses and microbes contained in the water, in proportion to the flow rate.
Since a large part of the chlorine is needed to neutralize these organic materials, the dose of chlorine delivered by the metering pump will allow a part, called free residual chlorine, to remain available to treat possible future contamination of the water in the network or in the homes.
According to the WHO, in drinking water treatment, the free chlorine concentration of the treated water should be 0.2 to 0.5 mg/l.
NSF/ANSI certification - Chlorine dosing pumps
The NSF/ANSI 61 & 372 standard was developed to establish requirements for potential adverse effects on human health of equipment in contact with drinking water (production, transport).
The NSF/ANSI 61 & 372 certified chlorine dosing pumps were subjected to a detailed toxicological analysis. The composition of each device (sub-assemblies, materials, suppliers) was analyzed and referenced by NSF International. Each device has undergone release tests to confirm that harmful particles do not migrate into the water.
The integration of NSF/ANSI 61 & 372 certified chlorine dosing pumps in water treatment applications offers a real alternative to standard dosing technologies, providing precision, robustness and ease of maintenance while protecting the health of users.
