On the other hand, the adsorption behaviour of polyacrylamide on to kaolinite particles is dependent on the charge density of each polyacrylamide. The isotherm for the adsorption of the cationic C 492, which has a charge density of 10%, approached a plateau at 150 mg l −1 of polymer dosing and the maximum polymer adsorbance achieved is 1.5 mg
POLYMER CHARGE AND MOLECULAR WEIGHT EFFECTS ON TREATED
Water soluble anionic polyacrylamide (PAM) polymer with 18% charge density and molecular weight of 12-15 MDa (MDa = 106 Dalton = Mg mold) has been shown to greatly reduce erosion and sediment losses and effectively increase infiltration in furrow irrigated soils (Lentz et al., 1992, 1998; Sojka et al., 1998b).

Soil & Water Management & Conservation Polyacrylamide
PAM are influenced by a complex set of relations among polymer properties (molecular weight, charge type, and density) and soil properties such as soil texture, organic matter content, composition and concentration of the soil solution, sediment properties, and soil clay mineralogy (e.g., Ben-Hur et al., 1992; Lu et al., 2002; Seybold,
PAM formulations (Pristine and Superfloc) were used in this study. Pristine (American Cyanamid Co., Wayne, NJ) is a 30% a.i. liquid emulsion (acrylamide/acrylic acid and ammonium salt plus 26% oil emulsion and 44% water) with high charge density (35% hydrolysis). The liquid emulsion contains a small

Kuljanin et al., Effect of molecular mass and surface charge of anionic polyacrylamide on pectin precipitation, Food and Feed Research, 45 (2), 169-177, 2025 were investigated the influence of surface charge density and molecular weight of anionic polyacrylamide (PAM) on the zeta potential and adsorption/flocculation beha-
(2016) evaluated the effect of charge density and molecular weight of C-PAMs on the growth and structural characteristics of GCC aggregates under neutral and alkaline conditions. In their study, high charge C-PAM formed larger and denser flocs than low or medium charge C-PAMs both in neutral and alkaline conditions.
- Is PAC a sustainable coagulant?
- Reduced Sludge Generation: A Sustainable Advantage In comparison to conventional coagulants like aluminium sulfate (alum), PAC offers a sustainable advantage with its reduced sludge generation. The formation of sludge during water treatment is a concern both environmentally and economically.
- Can polyaluminium chloride improve coagulation process in conventional water treatment?
- The coagulation process in conventional water treatment could be enhanced and the ensuing water pH decline reduced appreciably by applying the right dosage of polyaluminium chloride and appropriate process conditions of pH, fluid mixing speed matrix and residence time.
- Which coagulant is used in water treatment?
- Learn more about this versatile coagulant used in water treatment. Poly Aluminum Chloride (PAC) is a chemical compound that is used in various industrial and municipal applications. It is a coagulant and flocculant, which means it is used to remove impurities from water and wastewater.
- What is Pac water treatment?
- PAC is known for its high efficiency in treating water and has become a popular choice for water treatment facilities around the world. One of the key benefits of using PAC is its ability to effectively remove suspended solids, organic matter, and other contaminants from water.
