The History of Drinking Water Treatment - National Driller
Water treatment originally focused on improving the aesthetic qualities of drinking water. Methods to improve the taste and odor of drinking water were recorded as early as 4000 B.C. Ancient Sanskrit and Greek writings recommended water treatment methods such as filtering through charcoal, exposing to sunlight, boiling and straining.
Drinking Water. In general, people don't drink tap water, with bottled water being the norm. While it has been reported that tap water exceeds world standards for drinking water in many parts of the city, and the Metropolitan Water Works Authority has made a strong effort to exceed World Health Organization standards by 1999, in some places the water that comes out of the tap is still

- What is a polyacrylamide & oligomer?
- Polyacrylamide (PAM) & oligomers PAM is a water-soluble, odorless, white synthetic linear polymer with the repeating formula (-CH 2 CHCONH 2 -), and its monomer used is AM. Its molecular weight (MW) of PAM ranges from 10 5 to >10 7 Da, with a length of up to six million monomer units.
- What is polyacrylamide (PAM)?
- Polyacrylamide (PAM) possesses unique characteristics, including high water solubility, elevated viscosity and effective flocculation capabilities. These properties make it valuable in various sectors like agriculture, wastewater treatment, enhanced oil recovery, and mineral processing industries, contributing to a continually expanding market.
- Is acrylamide a polymer?
- The term “PAM” is commonly used to refer to any polymer that contains acrylamide as one of its monomers. Its IUPAC nomenclature is poly (prop-2-enamide) formed by linking acrylamide monomers or N, N ′-methylenebis (AM) ( Xiong et al., 2018a ).
