fairfield-suisun sewer district, ca. solano county, ca, 40 miles north san francisco. design capacity: 24 mgd tertiary treatment/ uv. population served: 135,000. polymer use for dewatering (screw press) and thickening (gbt) problems with existing polymer system. struggled to make proper polymer solution.
synthetic polymeric flocculants aid dewatering water technology,synthetic polymeric flocculants aid dewatering. march 1, 2000. most flocculants in use today are synthetic water soluble polymers based on acrylamide and its derivatives and which may include either anionic or cationic groups in a wide range of molecular weights and charge densities. they are supplied as dry powders or in liquid form as liquid
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
understanding polymer for thickening and dewatering processes,polymers can have different charges, charge densities, and molecular weights. polymers that have a positive charge (otherwise known as cationic) and a high molecular weight are typically used for thickening and dewatering solids separationprocesses. figure 3. a depiction of a floc formed by a cationic polymer chain bridging the solids particles.
novel methodologies for determining a suitable polymer for sale
since cationic polymers with high and very high molecular weight are widely used for conditioning and dewatering of wastewater sludge, especially for facility using centrifuges [26], the selection of appropriate polymers for conditioning generally focuses on the charge density and configuration of polymers. according to the y–intercept
basf expands production of polyacrylamide powder in nanjing,during the first quarter of 2019, basf has successfully ramped up commercial production of its new production line for polyacrylamide powder at its wholly-owned site in nanjing, china. the additional 20,000 metric tons per year capacity of polyacrylamide will support mining customers in asia pacific.
optimizing polymer mixing/activation improves sludge
ionic strength (hardness): multi-valent ion hinders polymer activation soft water helps polymer molecules fully-extend faster hardness over 400 ppm may need softener oxidizer (chlorine): chlorine attacks/breaks polymer chains should be less than 3 ppm caution in using recycled water for polymer mixing + serious negative impact on aging

- Can cationic polyacrylamide be used in water treatment and sludge dewatering?
- To read the full-text of this research, you can request a copy directly from the authors. Cationic polyacrylamide (CPAM) were used extensively in water treatment, enhanced oil recovery and sludge dewatering. The review summarized the synthesis methods research progress of cationic flocculants.
- Can cationic-surfactant polyacrylamide be used as a viscosifier in drilling fluid?
- Likewise, Shettigar et al. (2018) designed a cationic-surfactant polyacrylamide as viscosifier in drilling fluid, which showed the improvement of rheology and cutting effect due to the hydrophobic and electrostatic interaction between the surfactant (cetyltrimethyl ammonium bromide) and polymer.
- Can cationic polymers be used as primary coagulants in South Africa?
- The substitution of traditional hydrolysing reagents by cationic polymers (CPE) is becoming increasingly popular in South Africa, although no comprehensive investigation into the suitability of CPE as primary coagulants and their possible side-effects has been carried out.
