ETV Drinking Water Systems Center - NSF International
NSF International entered into an agreement on October 1, 2000 with the U.S. Environmental Protection Agency (EPA) to form a Drinking Water Systems (DWS) Center dedicated to technology verifications. With assistance from the EPA, NSF managed an Environmental Technology Verification (ETV) Center that provided independent performance evaluations

NSF International Certifies First Water Filters That
Protocol certifies products effective at decreasing microcystin from blue-green algae in drinking water to below EPA health advisory levels. Global public health organization NSF International has developed a test method - NSF Protocol 477: Drinking Water Treatment Units – Microcystin - that verifies a water filter’s ability to reduce microcystin to below the health advisory levels set by

Polyamines Certified by NSF International comply with 40 CFR 141.111 requirements for percent monomer and dose.
Public Drinking Water Equipment Performance - NSF
The NSF Guideline for Public Drinking Water Equipment Performance (PDWEP) and NSF/ANSI 419 establish performance requirements in the treatment and production of drinking water, and includes requirements such as the U.S. EPA’s Long Term 2 Enhanced Surface Water Treatment Rule (LT2ESWTR).
NSF International developed the microcystin test protocol at the request of regulatory agencies concerned about communities with elevated levels of microcystin in the lakes and rivers that serve as their primary source for public drinking water. Water filters certified to NSF Protocol 477: Drinking Water Treatment Units—Microcystin are

[1] All Chlorine from this facility is NSF Certified, whether or not it bears the NSF Mark. [CL] The residual levels of chlorine (hypochlorite ion and hypochlorous acid), chlorine dioxide, chlorate ion, chloramine and disinfection by-products shall be monitored in the finished drinking water to ensure compliance to all applicable regulations.
The new, selective Lewatit TP 107 ion exchange resin was developed specifically for municipal drinking water treatment facilities and is certified to NSF/ANSI standard 61. Lewatit TP 107 also offers key advantages in the industrial sector, such as for wastewater treatment in the leather and electroplating industries.
- What is copper-catalyzed controlled polymerization of acrylamide?
- Copper-catalyzed controlled polymerization of acrylamide (AM) has always been a challenge, which typically exhibits low monomer conversion and broad molecular weight distribution (MWD) or requires complex/multistep reaction procedures, due to the highly active nature of the AM radical and its side reactions.
- What is a high molecular weight nonionic polyacrylamide?
- High-molecular-weight nonionic polyacrylamides are routinely used in the mineral processing industries as thickeners and flocculants , , . 34.2.5. Polyacrylamide product forms The product types for polyacrylamides are solutions, liquids (emulsion or dispersion), and dry powders.
- What is nonionic polyacrylamide used for?
- Nonionic polyacrylamides are available from very low to very high molecular weights and are used in industrial wastewater treatment, mineral process, papermaking, and other industries. High-molecular-weight nonionic polyacrylamides are routinely used in the mineral processing industries as thickeners and flocculants , , . 34.2.5.
- How is polyacrylamide a hydrolyzed polymer?
- The process generally involves the addition of a strong base to a homopolymer of polyacrylamide. This can be done in an aqueous solution, inverse emulsion. Recently, a process to produce dry forms of hydrolyzed polyacrylamide has been developed. This allows for the preparation of very high-molecular-weight anionic polymers.
