The critical coagulation concentration (CCC) is a concept in wastewater treatment and clay science that states that for a given colloid in suspension there is a concentration of electrolytes at and above which the suspension will begin to undergo rapid coagulation. Critical coagulation concentration (CCC) of NaC1 and CaCl2 for kaolinite and montmorillonite was compared under different pH conditions. CCCs for both clays increased with pH, while kaolinite showing more pH dependent. Kaolinite coagulated below pH 6 and dispersed well above that for both Na- and 1995-11-01 above the critical coagulation concentration (CCC) has been analysed. The processes involved when bentonite swells until it becomes a non-swelling gel, which it will when the groundwater is above the CCC, have been analysed.

A perturbation method is adopted to solve the Poisson-Boltzmann equation governing the electrical potential distribution of the system under consideration. On th … Abstract: Critical coagulation concentration (CCC) is a key parameter of particle dispersions, since it provides the threshold limit of electrolyte concentrations, above which the dispersions are destabilized due to rapid particle aggregation. A computational method is proposed to predict CCC values using critical coagulation concentration otherwise critical aggregation concentration (rus. критическая концентрация коагуляции otherwise порог коагуляции) — minimum concentration of a coagulant that causes rapid coagulation. 2005-12-30 Corresponding Author.

Abstract: Critical coagulation concentration (CCC) is a key parameter of particle dispersions, since it provides the threshold limit of electrolyte concentrations, above which the dispersions are destabilized due to rapid particle aggregation. A computational method is proposed to predict CCC values using Critical coagulation concentration (CCC) of a biocolloidal suspension is investigated theoretically by taking into account the influences of cationic absorption in particulate membrane phase, variation in dielectric constant, size of charged species and nonuniform distribution of fixed membrane groups. The table below summarizes the critical coagulation concentration (CCC) ranges for different net charge of the counter ion. The charge is expressed in units of elementary charge.

Critical coagulation concentrations for spherical particles of a given material should be proportional to e3 and independent of particle size. Some other practical situations where particle aggregation is important include the precipitation of colloidal mud at the mouth of a river due to the salinity of the sea-water exceeding the critical coagulation concentration, land (e.g.

Calculating Critical Coagulation Concentration. In order to calculate the The critical coagulation concentration is strongly dependent on the type of colloidal system and coagulant.

Here, the concentration of particles is high so that the classic DLVO theory, which is based on the interactions between two particles, can be inapplicable. A statistical mechanics approach based on the Ornstein-Zernike model and Percus-Yevick relation is adopted to estimate the total interaction A Simple Method to Determine Critical Coagulation Concentration from Electrophoretic Mobility 1. Introduction. Dispersions of nano or colloidal particles attract widespread contemporary interest due their extensive 2. Calculating Critical Coagulation Concentration. In order to calculate the The critical coagulation concentration is strongly dependent on the type of colloidal system and coagulant. In electrolytic coagulants the efficiency of coagulation increases sharply with increasing ion charge.
