PolyDADMAC - Wikipedia

Polydiallyldimethylammonium chloride (shortened polyDADMAC or polyDDA ), also commonly polyquaternium -6, is a homopolymer of diallyldimethylammonium chloride (DADMAC). The molecular weight of polyDADMAC is typically in the range of hundreds of thousands of grams per mole, and even up to a million for some products.

AN OPERATOR¡¯S GUIDE TO WATER TREATMENT COAGULANTS

Organic coagulants include the so-called polyDADMAC (polydiallyldimethyl ammonium chloride) range of cationic polymers. These are special and expensive chemicals that are sometimes used in direct filtration plants when the low doses required make their use economical.

Enhancement of flocculation and dewaterability of a highly stable

Floc size analysis is conducted on the sludge conditioned with coagulants only and coagulants-flocculants hybrid system. As mentioned earlier, polyDADMAC and polyamine coagulants act as destabilizers and produce small flocs. Fig. 5 shows an example of the floc size distribution of sludge conditioned with FL 2949.

Comparison between APAM and polyDADMAC as flocculant aids shows that APAM can achieve stable removal at wider pH range and lowest sedimentation time at 20 min while polyDADMAC was at one hour. Both dual coagulants were followed second order kinetic and APAM shows the highest rate over polyDADMAC i.e. 3 ¡Á 10 /PtCo.min and 2 ¡Á 10 Keywords Biogas

polyDADMAC coagulants are the most common type used in the mining industry. polyDADMAC coagulants are typically supplied as liquid solutions varying between 10-40% actives. SD Series Coagulants were developed to capture the performance benefits of 100% active polyDADMAC. SD Series Coagulants are liquid dispersions of 100% polyDADMAC micro-beads.

Nitrosamines form in the presence of chloramine disinfectants during drinking water treatment. Drinking water treatment relies upon chemical addition, including cationic polymers (e.g., polyDADMAC), to achieve turbidity and pathogen removal. The present study shows the contributions of cationic polymer to nitrosodimethylamine (NDMA) formation ...

The study offers a comparison of floc physical characteristics for coagulant precipitate flocs, organic-coagulant flocs and organic-coagulant-polymer flocs for optimum coagulant and polymer doses. A ferric sulphate-based coagulant was used as the primary coagulant and the polymer selected was a high molecular weight (MW) cationic polydiallyldimethylammonium chloride (polyDADMAC).

PosiDAF performed better with PolyDADMAC (with a dose of 334 ppm, the highest COD reduction was 100%) than with Epi¨CDMA (with a dose of 596 ppm, the highest COD reduction was 93%) for the treatment of O/W emulsions. The COD reduction was higher when the concentration of both the PolyDADMAC and Epi¨CDMA was higher in the saturator.
