the role of coagulation in water treatment

The role of coagulation in water treatment

Coagulation is a process for combining small particles into larger aggregates (flocs) and for adsorbing dissolved organic matter on to particulate aggregates so that these impurities can be removed in subsequent solid/liquid separation processes.

Evaluation and optimization of enhanced coagulation process: Water

Coagulation is a general term for the two processes of coagulation and flocculation (Huang et al., 2018). It is the aggregation process of microscopic suspensions of colloidal particles in water (Jiang, 2015 ). Aggregation induces the loss of stability of the colloid in the water after the addition of the coagulant.

However, more recently, coagulation has been shown to be an effec-tive process for the removal of many other contaminants that can be adsorbed by col-loids such as metals, toxic organic matter, viruses, and radionuclides (1,2). Enhanced coagulation is an effective method to prepare the water for the removal of certain con-

Polyaluminium chloride dosing effects on coagulation performance: case

Various sets of jar flocculation tests were conducted at pre-determined pH values to establish the effect of pH changes on coagulation . Prior to the start of each jar test, the raw water's pH was adjusted to a pre-determined pH value within the range 6.0 to 8.5, using 0.10 N HCl or NaOH.

Coagulation and Flocculation

Abstract. Coagulation and flocculation constitute the backbone processes in most water and advanced wastewater treatment plants. Their objective is to enhance the separation of particulate species in downstream processes such as sedimentation and filtration. Colloidal particles and other finely divided matter are brought together and

Analysis and optimization of coagulation and flocculation process

AbstractNatural coagulants have been the focus of research of many investigators through the last decade owing to the problems caused by the chemical coagulants. Optimization of process parameters is vital for the effectiveness of coagulation process. In the present study optimization of parameters like pH, dose of coagulant and mixing speed were studied using natural coagulants sago and

This process is called flocculation. Calcium hydroxide (also known as lime) raises the pH of the mixture and produces more charged species (electrolytes) on the suspended particles. These charges are extracted and increase the size of the solid (coagulate) which simplify the filtration process. The slightly basic water causes Al (OH) 3, Fe (OH

coagulation (water treatment)

Coagulation (water treatment)

Coagulation itself results in the formation of floc but flocculation is required to help the floc further aggregate and settle. The coagulation-flocculation process itself removes only about 60%-70% of Natural Organic Matter (NOM) and thus, other processes like oxidation, filtration and sedimentation are necessary for complete raw water or wastewater treatment.
