City of Tempe, AZ Improves Water Quality with Lamella
The Johnny G. Martinez Water Treatment Plant is one of two water treatment plants in Tempe, AZ. Due to population growth there was a need to expand the plant to 80 MGD capacity. During expansion the plant became the first large scale UV facility for drinking water disinfection in Arizona. Prior to UV disinfection, post filtration is necessary.

Using a membrane bioreactor/reverse osmosis system
The City of McAllen, Texas, with the assistance of CH2M HILL, has pilot tested an integrated membrane bioreactor (MBR)/reverse osmosis (RO) treatment train to reclaim municipal wastewater to a quality suitable for use as a new drinking water supply in the process called indirect potable reuse.

From micro to macro-contaminants: The impact of low-energy
Membrane fouling was assessed by flow of permeate passing through the membrane under constant pressure, quantified as the cumulative mass of permeate collected. Permeate mass was recorded every 10 s until the membrane had fouled, as signified by negligible water passage across the membrane (i.e., negligible change in the mass of permeate).

- Why did polyacrylamide prices rise?
- Market stability was attributed to positive supply–demand dynamics. The polyacrylamide prices rose as consumer demand from the downstream flocculant and lubricant industries rose. As inventory stocks started decreasing and production prices rose, the upstream costs increased, thereby exerting pressure on the polyacrylamide prices.
- Why did polyacrylamide prices rise in H1 2025?
- Polyacrylamide prices in Europe stayed on an inclining trajectory in H1 2025. As the demand from water treatment plants was on the rise, the prices increased in the market. For the European market, expensive imports from China hiked the prices further. As polyacrylamide consumption increased across the globe, manufacturers raised their quotations.
- How do you make polyacrylamide?
- One of the ways to produce polyacrylamide is via emulsion polymerization of acrylamide in which aqueous acrylamide solution is dispersed in a solvent like gasoline accompanied by vigorous stirring until the solution is uniformly dispersed followed by the addition polymerization of acrylamide to give polyacrylamide.
