Did you know that certifying and/or registering your water treatment chemicals can open doors to new end-use applications?
Let’s look at the treatment of potable water, swimming pool water, cooling and retort water, and boiler water. Some typical problems addressed by water treatment chemicals and examples for each of the certified and registered chemicals that are commonly used are listed below.
Note: The examples below are not an exhaustive list.
Drinking water must be free of suspended solids, microorganisms and toxic chemicals. In addition, most minerals have a recommended maximum concentration to ensure safe, odor-free and clear water to drink. For municipal drinking water, attention is also paid to corrosion and scaling of the water in order to maintain distribution piping in good condition. Important drinking water treatments include:
Swimming pool water must be treated in order to remain clean and crystal clear, safe and inviting for swimmers. Potentially harmful substances, bacteria, viruses, algae and other pathogens need to be removed. Important swimming pool water treatment processes include:
Common problems are corrosion of metal components, scale deposits and fouling caused by microbes and biofilms. Important cooling and retort water treatment processes include:
Boilers can be damaged by calcium-based scale and metallic corrosion. In addition, minerals and impurities are common problems. Important boiler water treatment processes include:
If you want to sell your chemical products to new markets, show that your products comply with the highest international standards. The NSF mark provides assurance that your products have been evaluated by an accredited, objective third party and that they meet stringent public health standards.
NSF offers testing, certification and registration services for many treatment products. Certified products appear in NSF’s online searchable listings. This listing is used by buyers to select products and by public health officials to verify NSF certification and/or registration.
