isolation and characterization of polyacrylamide-degrading,abstract: polyacrylamide (pam) is a water-soluble polymer that is widely used as a flocculant in sewage treatment. the accumulation of pam affects the formation of dewatered sludge and potentially produces hazardous monomers. in the present study, the bacterial strain hi47 was isolated from dewatered sludge.
cationic polyacrylamide copolymers (pam): environmental half
background cationic polyacrylamide copolymers (pam) are used for sludge dewatering in municipal waste water treatment and might enter the environment by spreading of the sludge on agricultural land. concern has been expressed since little is known about the degradation of pam in soils. to obtain detailed information on the polymer’s fate in the soil compartment, the degradation of 14c
research on a new cationic polyacrylamide (cpam) with high quality,flocculation is one of the commonly used sludge conditioning methods in water supply plants, which can improve the sludge dewatering performance by reducing the specific resistance of sludge (srf), decreasing the amount of sludge, and finally lowering the transportation cost and subsequent disposal cost of sludge. therefore, it is particularly important to develop new and efficient flocculants

- What is anionic polyacrylamide?
- technology-oriented and customer first. Anionic Polyacrylamide is produced when acrylamide is polymerized with an anionic comonomer. Water soluble Polyacrylamide have been used for decades to facilitate solidliquid separations in wastewater and drinking water treatment, the pulp and paper industry, aquaculture, and many other industrial processes.
- Which emulsion forms of anionic polyacrylamide should be avoided?
- Emulsion forms of anionic PAM should be avoided. Residual acrylamide content less than 0.05%. Top anionic polyacrylamide flocculant powder supplier, which provides efficient reliable polyacrylamide (PAM) solutions for water treatment and pulp and paper making, mineral washing.
- How much acrylamide should be used in a Pam emulsion?
- High molecular weight. The anionic PAM used in the product should have a molecular weight between 6 and 24 mg/mol, with 12 to 15 mg/mol preferred. Emulsion forms of anionic PAM should be avoided. Residual acrylamide content less than 0.05%.
- What are anionic Polyacrylamide flocculants used for?
- Today there are several anionic polyacrylamide flocculants -based products marketed for use in construction site sediment management. These products can be applied for erosion control, clarification of sediment laden runoff, and de-mucking of wet sediment during pond cleanouts.
