Polyacrylamide degradation and its implications
High molecular weight (106–3 × 107 Da) polyacrylamide (PAM) is commonly used as a flocculant in water and wastewater treatment, as a soil conditioner, and as a viscosity modifier and friction
Abstract. The effects of sodium chloride, sodium sulfate, and alum (aluminum sulfate) on the performance of a cationic polyacrylamide flocculant in a papermaking suspension consisting of bleached (hardwood: softwood, 50∶50) kraft wood-pulp fibres and anatase (TiO 2) were investigated.Sodium chloride and sodium sulfate, 1×10 −5 to 1×10 −2 M, in the presence of polymer, caused negligible
A Novel Flocculant of Poly Aluminum Silicate Sulfate
A novel flocculant based on polyacrylamide-poly aluminum silicate sulfate (PAM-PASS) has been synthesized using a redox initiation system ((NH4)2S2O8–NaHSO3) at 40℃ in aqueous medium.
Treatment of anionic emulsion systems using chitosan, polyacrylamide, and aluminum sulfate Article in Scanning 21(5):354 - 358 · September 2006 with 20 Reads How we measure 'reads'
Comparative Assessment of Performance of Aluminium
Request PDF | Comparative Assessment of Performance of Aluminium Sulphate (Alum) and Ferrous Sulphate as Coagulants in Water Treatment | Alum and ferrous sulphate, being among the best-known
aluminum sulphate and calcium hydroxide as coagulants, and polyacrylamide as flocculant by varying pH from 5 to 7 and coagulant dosage from 100 to 300 mg L –1 at constant flocculant dosage
Fast and Sensitive Colloidal Coomassie G-250 Staining
Fast and Sensitive Colloidal Coomassie G-250 Staining for Proteins in Polyacrylamide Gels. Instead of ammonium sulfate they used aluminum sulfate and methanol was replaced by the less toxic ethanol 4. The novel aluminum-based staining in Kang's study showed superior sensitivity that detects as low as 1 ng/band (phosphorylase b) with little
Study of the effect of aluminum sulfate and polyacrylamide during clarification and filtration of a fluorite concentrate suspension. Journal of Mining Science 1993, 28 (5) , 485-491. DOI: 10.1007/BF00711135. T.M. Herrington, A.Q. Clarke, J.C. Watts. The surface charge of kaolin.
Treatment of the production waste water of Konstantinovka
The coagulating action of aluminum sulfate and of the combination of it with polyacrylamide on a suspension of chamotte and clay, leading to a significant increase in particle size of the dispersed phase, was investigated. The presence of a threshold value of the addition of coagulant as an important production parameter determining the unstable suspension type sedimentation of particles was
The process of filtering the residues formed in purifying the effluent depends on the composition of the residues and the method of treatment. The highest productivity levels of the drum vacuum-filters are obtained by treating the suspensions together with aluminum sulfate and polyacrylamide; optimum values are also obtained for the outputs of beltvacuum filters for these residues.
Optimization of Coagulation and Flocculation in Fat
The coagulation activity of aluminum sulfate and products of its hydrolysis was analyzed. Formation of particles in fat-containing disperse systems in the presence of both the coagulant and its mixtures with flocculants based on polyacrylamide was studied.
Abstract. Aluminum dross tailings, an industrial waste from the Egyptian Aluminum Company (Egyptalum), was used to produce two types of alums: aluminum sulfate alum (Al 2 (SO 4) 3 ·12H 2 O) and ammonium aluminum alum {(NH 4) 2 SO 4 AL 2 (SO 4) 3 ·24H 2 O}. This was carried out in two processes.
