Synthesis and application of nonionic polyacrylamide with controlled molecular weight for fracturing in low permeability oil reservoirs, Journal
Nonionic polyacrylamide (NPAM) with controlled molecular weight was successfully synthesized as a gel fracturing fluid by aqueous solution polymerization. The effects of the monomer concentration, initiator concentration, reaction time, feeding
The thermal gelation behavior of nonionic polyacrylamide (NPAM) and PEI was investigated, and sodium citrate (NaCit) was selected as a new retarder to prolong the gelation time. The gelation performance of NPAM/PEI gel system can be adjusted by
Biodegradation of polyacrylamide by anaerobic digestion under mesophilic condition and its performance in actual dewatered - ScienceDirect
Polyacrylamide (PAM) used in sludge dewatering widely exists in high-solid anaerobic digestion. Degradation of polyacrylamide accompanied with accumulation of its toxic monomer is important to disposition of biogas residues. The potential of
Amphoteric polyacrylamide also can be called amphoteric polymer or amphoteric polyelectrolyte. Buy amphoteric polyacrylamide (PAM) from Sinofloc amphoteric flocculants supplier. 1. Industrial water treatment Amphoteric polyacrylamide has been

3. Product Features High viscosity, quick dissolving rate, less residual content, easy handling without foam during stirring. Low dosage, reduced power use, enhanced machine speed and production capability. Promote the dispersal of the fibre
Polyacrylamide gels are characterized by two parameters: total monomer concentration (%T, in g/100 ml) and weight percentage of crosslinker (%C). By varying these two parameters, the pore size of the gel can be optimized to yield the best

Grafting of polyelectrolytes onto polyacrylamide by reactive processing | Semantic Scholar
Low-molecular-weight high-charge-density cationic poly diallydimethyl ammonium chloride (polyDADMAC) was grafted onto nonionic polyacrylamide (PAM) using organic peroxide initiators in the molten state carried out in a batch mixer. The graft
Nonionic polyacrylamide and polyacrylamide-based microgels are also used in water shut-off treatments for gas and oil wells. A comparative study of the mechanical degradation for three linear
- How does the Buenos Aires water supply & sanitation program work?
- These measures will help reduce greenhouse gas emissions, such as the methane gas produced in wastewater treatment. The Buenos Aires Water Supply and Sanitation for Vulnerable Areas Program is financed with a variable-spread loan that supports results-based management, with specific indicators to measure compliance.
- What is the level of wastewater treatment in Argentina?
- The level of wastewater treatment varies among the Argentinean regions. According to the Pan American Health Organization, at the national level 10% of the collected wastewater was being treated in 2000.
- Are private water companies more common in Argentina?
- In Argentina, as in other Latin American countries, state owned water companies are more common than privately operated utilities.
- What is chlorine used for in water treatment?
- Chlorine is widely used for the treatment of drinking water (Gopal et al. 2007). For instance, in Canada, approximately 90 % of water treatment systems use chlorine for disinfection (Health Canada 1995; Health Canada 2008).
