Trichloroisocyanuric acid for pools

Weifang JS hydrolyzed polyacrylamide (HPAM) is a synthetic, high-molecular-weight chitosan-like polymer that has NH2 groups on its side chains that form hydrogen bonds with other polymers. HPAM, like chitosan, is a strong adsorbent of metal ions and has high flocculating efficacy.

For hydraulic fracturing that doesn't use water, HPAM is often used to change the way displacing fluids behave.  However, the salt tolerance and viscosity of HPAM at elevated temperatures limit its use.

Degradation HPAM

The flocculant, Weifang JS high molecular weight polyacrylamide (HPAM), is used in water and wastewater treatment, soil conditioning, and viscosity modification in enhanced oil recovery (EOR). Its persistence in the environment despite biodegradation has caused significant environmental problems.

Under the typical thermophilic conditions found in environments like oil and gas reservoirs, however, it is not clear if HPAM can be used by microbial communities to provide nitrogen. We used microbial communities enriched with oilfield produced water (PW) and wastewater sludge to use PAM and HPAM for N sources below 50 degrees Celsius.

Upon incubation, PW and sludge microbial cultures readily utilized PAM and HPAM as N sources (CO2 accumulation) at 50 u00b0C but did not utilize HPAM or PAM as a sole C source (NH2 removal). Conclusion: Our results demonstrate that PAM and HPAM can serve as effective N sources under thermophilic conditions and provide valuable insights into the fate of these compounds in subsurface environments.
