Abstract. In various applications of polyacrylamide (PAM) in soil erosion control, soil conditioning, water treatment, and oil recovery, the polymer mainly reacts with clay minerals. The objective of this study was to investigate the probable
Polyacrylamide Gel Electrophoresis | Cleaver Scientific
Polyacrylamide gel electrophoresis (PAGE) is a technique use almost universally in life science laboratories. The goal of this technique is to separate a mixed sample of proteins to identify and quantify single proteins from the mixture. The
Effect of temperature and low pH on structure and stability of matrix porin in micellar detergent solutions. Markovic-Housley Z, Garavito RM. Thermal and low pH stabilities of matrix porin (Omp F) solubilized in the micellar solutions of ionic
Surfactant-Modulation of the Cationic-Polymer-Induced Aggregation of Anionic Particulate Dispersions
polyacrylamide flocculants (cationic, anionic and nonionic) of varying ionic character in the presence of cetyl trimethyl ammonium bromide (CTAB), SDS, and Triton-X 100. Karlson et al. [25] explored the interaction of two cellulosic polymers,
Thus, nonionic polyacrylamides are used in situations where the anionics are incompatible with other molecules. The amount of charge is measured as a percent of the comonomer added. Thus, a polyacrylamide that is 30% acrylate and 70% acrylamide
MALDI mass spectrometry analysis of high molecular weight proteins from whole bacterial cells: Pretreatment of samples with surfactants
Therefore, many recommend that deter-gents be removed before MS analysis [12–14]. Nilsson reported on the use of nonionic surfactant with different matrices for the analysis of proteins contained in the bacterial lysates and extracts using

- Can CFD modeling be used in water treatment flocculation?
- The CFD approach can be applied to study the hydrodynamic behavior of the full scale flocculation system, and optimize the operational conditions at the limit or beyond design capacity. A review of CFD modeling in water treatment flocculation processes is presented by Bridgeman et al. .
- What is coagulation flocculation?
- The coagulation flocculation is considered the most important process in water surface treatment. Coagulation allows by the injection and the scattering of chemical (coagulants) during relatively intense mixing to destabilize naturally occurring particles and macromolecules and/or to precipitate additional particles (Mackenzie and Cornwell 1991).
- How does flocculation work?
- Introduction Flocculation is a crucial unit operation in drinking water and wastewater treatment. By using flocculation chemicals, the smaller destabilized particles are agglomerated into larger ones, known as flocs. Then, the flocs are separated by the solid-liquid separation process as filtration or sedimentation to decrease turbidity and color.
- Are settled turbidity removals dependent on flocculation conditions?
- Settled turbidity removals were dependent on the applied mixing conditions. Filtered turbidity was found to be independent of the investigated flocculation conditions, which calls into question the true value of mixing conditions with substantial implications on facility design, operation, and regulation.
