novel thermodynamic mechanisms of co-conditioning with polymer aluminum chloride and polyacrylamide for improved sludge dewatering: a paradigm
this study investigated the combined effects of polymer aluminum chloride (pac) and polyacrylamide (pam) on sludge dewatering, aiming to unveil underlying mechanisms. co-conditioning with 15 mg g −1 pac and 1 mg g −1 pam achieved optimal dewatering, reducing specific filtration resistance (sfr) of co-conditioned sludge to 4.38 × 10 12 m −1 kg −1, a mere 48.1% of raw sludge’s sfr.
understanding the synergistic mechanism of pam-fecl3 for good price,assuming that the output of the sludge (moisture content 98%) is 2500 t/·d-1 in the sludge treatment plant, the cost of traditional cpam is as high as 75,000 $/d, while the cost of hybrid flocculant pam-fecl 3 is approximately 50,000 $/d. compared with the cost of cpam, the cost is reduced by 33.33%.

fig. 4 shows sem images of pu foam materials with raw and ball-milled ti 2 o 3, respectively.it can be seen from fig. 4 a and b that all of the pu-derived photothermal foams exhibit three-dimensional structures with open-pores and closed-pores, which can induce multiple reflection and refraction of incident solar light and thereby increases the efficiency of photothermal conversion.
water soluble polymer flocculants synthesis,polymer adsorption can occur through hydrogen bonding (polyacrylamide on silica silanol groups), electrostatic interaction (cationic polymers on negatively charged sludge), hydrophobic interaction (poly(vinyl alcohol) on silver iodide), and ion bridging (anionic polyacrylamide on negatively charged clays with the help of divalent calcium ion). 7
