Polyacrylamide flocculants

Woodberry, N. T. (1961). A new, anionic, polyacrylamide flocculant. Tappi, 44, 156A-60A. [Pg.196]

The flocculation responses studied are settling rate, percent solid settled, supernatant clarity, sediment volume and slurry viscosity. The polymer concentration and polymer anionicity required for maximum flocculation were seen clearly to depend on the response studied. Both the settling rate and the supernatant clarity with the nonionic polyacrylamide flocculent showed at pH 4.5 a marked increase to a maximum at about 25 mg/kg, whereas with the anionic polymer settling rate and supernatant clarity showed maxima at 10-25 mg/kg, but the system was totally... [Pg.407]

Leung [3] used size exclusion high performance liquid chromatography to determine down to 20ppm of polyacrylamide flocculants in waste waters. Ultraviolet detection at 205nm showed higher sensitivity than infrared detection. [Pg.206]

The process of formation of polyacrylamide flocculant on the basis of acrylonitrile and sulphuric acid in one stage was investigated. The required properties of flocculant can be obtained as result of achievement of the optimal rates ratio of reactions of polymerization and hydrolysis, which proceeds in the synthesis conditions simultaneously. [Pg.379]

The polyacrylamide flocculant can be produced by hydrolysis the polymer which contains acrylonitrile groups [4], The product of such reaction has much less molecular mass (approx. 5 104) and flocculating activity, than the product of AA polymerization. [Pg.380]
