    PolyDADMAC and polyacrylamide as a hybrid flocculation system

    The flocculation performance tests were carried out in jars with polyDADMAC and polyacrylamide (PAM) dosages of 0.4–2.0 mg L −1 and 0.4–8.0 mg L −1, respectively. The tests were conducted at a rapid mixing rate of 200 rpm for 2 min, followed by a slow mixing rate at 30 rpm for 10 min, and settling time of 5 min. Polyacrylamide was

    As mentioned earlier, smaller and more compact flocs are produced when the hybrid coagulation-flocculation system is used and CST values are higher in comparison with the use of PAMs alone (Fig. 6b). However, the massive reduction in the flocs sizes does not increase the CST values significantly except when FO 4490 SSH (linear PAM) was used.

    Treatment of Pulp and Paper Mill Wastewater with Various

    Flocculation studies between dual polymers on pulp and paper mill wastewater are reported in this paper. The effects of different molecular weights of polyDADMAC and different dosages of Polyacrylamide (PAM) were studied. The molecular weights of polyDADMAC used were 8.8×104, 10.5×104 and 15.7×104 g/mol.

    Poly(DADMAC) was made by free radical polymerization and physically blended with MgCl 2 in an aqueous solution at five different ratios. The mixtures were then aged at room temperature for 24 h. Poly(DADMAC) also improved the flocculation ability of the composite flocculant by bridging the suspended particles.
